Yup. I usually loaded to 29 but a lot of guys did 28. The middle of a gun fight is a terrible time for a weapons malfunction. Especially one caused by the operator.
Back in Afghanistan I voluntarily traded my M4 for a M249 and stopped worrying about such things, had over 300 rounds in various softmags and a spare barrel for when things got hot. Also I was 5'11" 168lbs mostly muscle so I didn't mind the extra weight that much.
Combat veterans may have AR's at home but they didn't carry them in service. An AR isn't a military weapon like so many on the left want to claim. I know you probably know that but I like putting it out there often to try to get through the misconception
For those curious, although it's possible to fit 31 rounds in an AR mag, there's a drawback. You can't insert the magazine into the rifle because the spring lacks sufficient give to make room for the bolt carrier, meaning the magazine cannot move past the mag catch. Even if you manage to force it into the rifle, the spring pressure on the bolt carrier would be too high for reliable function in the first 2 or 3 rounds. So while it is a neat party trick it is not something you should do for an extra round or two, just buy a dedicated 32 round mag instead if you really need the extra rounds. Edit: With the bolt open it may or may not work, it depends on the spring pressure from the buffer spring and how well lubricated the rifle is. However, it can be done somewhat reliably if the rifle has enough spring pressure and is well lubricated, though it would only work if the bolt were open, such as during a reload. However, the extra round in the magazine causes more wear to the spring and feed lips as the magazine was not designed to hold more than 30 rounds.
Not only that but some guns are closed bolt meaning they can do an extra round since the bullet is on the chamber but if its open bolt it can't do that...
Yup. When I took my buddy shooting for his first time I made him load mags and he loaded 31 rounds, tried to insert mag and it wouldnt seat I thought he somehow managed to break it😂
I just put blue tape on the 31rnd mags, and use th3m only as the first mag when training, and ill remove a round, slot th3 mag, and load the rnd into the rifle and charge the weapon
The room is so you can have 30 and still easily load the mag into a charged weapon system. Which use to be a problem so we would load 29-28rds in the mag for easier reloads.

The 31 round mag was Magpuls response to the issue of standard 30 round mags being difficult to seat, leading to common practice being to put 29 rounds in. 31 round mags are more reliable with “only” 30 rounds.
This is true. Many high cap magazines, even with pistols, are far more reliable by downloading the number of rounds by 1. Thus as you've said, by them making the magazine able to hold another round then what you plan then to hold, allows for a higher reliable use of them. I know military guys who refuse to use magazines designed any other way.
@Shuck-Shick-Blam In the Marines I always loaded to 29 rounds. Some guys would do 28. As you said, this was to ensure easy mag insertion and proper weapon function every time. But please, let's stop calling them hi-capacity mags. That's a gun grabbers term. 30 rounds in an M-16 or AR-15 is a STANDARD CAPACITY magazine.
Yes the mag can take 1 more bullet, but does the rifle function correctly with no malfunctions or problems with the magazine loaded pass the factory magazine capacity???
One of the problems with magazines is the plastic sides where the round presses against. Over time they can deform with the constant spring pressure. For this reason these mags come with a dust cover that presses the round down off the sides relieving the tension. That "hidden trick" isn't extra space to force another round in, it's extra space to afford you the ability to preserve the side lips and keep your mags running smoothly for longer.
The extra space is for better feeding, less stress on the feed lips, and it allows you to put their dust covers they come with on when the mag is full.
And the dust covers are designed for more than just keeping debris out. They're actually designed to keep pressure off the feed lips during storage. And an added feature is that the dust covers make the mag be considered an enclosed container, which means you can leave your mags loaded when you fly, only if you have a dust cover on it
Multiple reasons not to do this. 1. Spring/feed lip damage. 30 is fine but already debated heavily. Dont do 31 2. Mag seating. 30 is fine but sometimes needs a slap. Dont do 31 3. Round count. Only a 3% increase in round count isnt worth the trouble. If you want more, carry another mag. 4. Odd numbers. 30 is a good number. Theres a reason they arent designed to hold 27 or 31 rounds. Its more work to keep track of your round count. 5. Loading. Loading 31 is more effort and some magazines wont even fit them in.
That space in the magazine that allows you to add that one extra round is specifically designed so you can seat the magazine on a closed bolt effortlessly. Don’t add the extra round.
Exactly. I thought I had a major issue when racking one to the chamber until I realized I overloaded the mag with an extra round by not paying attention. and then prior to that, I really sat there wondering why it was so hard to catch on the mag release?! 🤦♂️
Lol, this is why you have short bus commandos telling everyone they need to download thier mags to 29....the overloaded thiers a few times and found the issue went away.
@CollKill2 lol, that's obviously asking too much....and really you don't even really need to count in most cases, it's just a box and a half, 3 boxes of 20 rounds is 2 loaded mags. Lol

When storing your POLYMER mag with no metal lip, it is recommended not to put the full capacity. It's better to put 1 or 2 less so as not to damage the lip. Also, having less 1 or 2 rounds, will have a better feeding function.
Firstly, those are two different generations of pmag Secondly, this is dumb, the ability to add an extra round is due to the mag being designed to seat easily in a weapon with a closed bolt. This is a good way to wear down and screw up your mags. Drop one like this and the chance of a round falling out is high. Store them like this and you risk breaking feed lips.
What the fuck is the difference between the generations I have one twos and threes all of them hold 30 rounds all of them shoot exactly the same none of them have any issues I don't know what the fuck you guys are all talking about
That extra room is there by design to load a 30 rounder into a closed bolt. If you put the 31st round there’s not enough room for it to compress and lock in. 30 rounders are just that….30 rounders
You can do it with every mag besides the metal magazine I have a ton of every type of mags I have a couple few mft mags magpull random polymer magazines and thy all fit 31 but the bad thing is, it's hard to put the magazine in the gun on a closed bolt
I was going to say it but yeah I’m happy that there’s a lot of educated gun owners out there that already nailed it. 1 in the chamber and 29 in the mag is what the new generation does and it works well. If your mag doesn’t work, make sure you have it marked and get it taken care of.
Dont use 31 rounds. The reason you can put 31 rounds in it is because the old usgi mags had to be downloaded by 1 round to make a 29 round mag because there wasnt enough give to insert a mag on a closed bolt. To fix this most modern AR mags are actually 31 rounders, because you would want one less then it can hold to have enough play to insert on a closed bolt.
This is patently false. A full 30 in a GI mag inserts perfectly fine on a closed bolt. If you’re having problems inserting a full mag I suggest getting stronger
@@JazzIs4urSouldoesn’t require strength it’s literally made to be inserted fully loaded so if you gotta be “strong” or slam that mf in there something is wrong with the magazine or magazine catch itself
@@jeremiah0628 I’m saying it’s literally made for it. If you can’t overcome the minute amount of spring pressure compressing the full 30 you’re a bitch
The extra space is meant to resolve any mag seating issues with the bolt forward. With the bolt forward, this mag loaded to 31 will not seat no matter how hard you smack.
A fully loaded 30rd mag still requires more force to seat properly when the bolt is closed.I only load 29 rounds for consistency, but end of the day it’s all preference.
Always load even numbers, such as 28 in a 30 rd mag or 18 in a 20 rd mag, or 26/ 16 and down, so as to have the round on the right side of the lips for the top round in the mag for a reliable strip and chambering @joshuatomasian6202
Putting 31 rounds in that magazine may make it difficult - if not impossible - to insert the magazine into the rifle with the bolt in the forward position. To avoid unpleasant surprises during an emergency, I'd recommend that you only load 30 rounds into the magazine.
No, you cannot, you need that extra spring play for reliable operation. This is dangerous and will lead to gun malfunctions. Please take this down for safety reasons.
so you have heard people say that you should only load 28-29 rounds in a 30 round mag for reliable feeding. they are talking about putting the mag in the gun, with 30 rounds in an older style 30 round mag, you would really have to slam the mag in with some gusto most of the time to get it to seat. Magpul has added a bit more clearance (which allows a 31st round to fit) so that you can load 30 rounds, and still put the mag in reliably without having to slam it home every time. its nothing to do with "feeding" or them marketing a 31 round mag as a 30 round mag, the space is there for a reason and its not to put a 31st round in it.
When people’s guns won’t load a round or they can’t load the magazine into the gun when needed, it will be their own fault for listening to this guy 🧐😏
I agree with many here. I have all mine with 28 rounds in them so i have way less chance of feed issues. Getting 2 rounds stuck very hard in there twice had me change a few things a few years ago. Nearly impossible to get it operable again without a brass rod. I dont want to cause a condition in the feild that causes tools needed that i dont keep on me.
Look bruh, my point is I called it a cheater for lack of a better name coming to mind at the moment I made the original comment. Then, to appease your sensitivities, I clarified it as a round loader, speed loader, etc. Now you’re just being petty. I really didn’t mean to imply you are a cheater by using one. Lastly, I fully reject the implication that I am annoyed. I’m just trying to educate you on how synonyms can be applied in the English language.
The extra travel is so you can insert 30 round mag on a closed chamber. Also 31 round loaded mags could lead to critical compression of the spring leading to earlier spring failures
Springs don’t get “fatigued”. There’s videos explaining this, and the physics and engineering behind it. People would only do 28 or 29, because doing 30 would cause poor seating of the mag in the lower. Due to the 30th round preventing slack in the spring to prevent the mag from fully inserting and locking into place. Hence why they came out with this “31 round mag”. Allowing for a true 30 round count mag.
@@shanktrujank1294 That makes sense. Both reasons are probably true because springs do deteriorate. But it takes a long time and doesn't happen to everyone.
There is a caveat here, yes you can fit 31 rounds in a Pmag, but if you’re bolt carrier is forward you can’t properly seat the magazine. The extra give that happens with only 30 rounds is room needed for the bolt carrier.
The extra space is to allow inserting a fully loaded magazine into the mag well with the bolt forward. USGI magazines, when fully loaded, have issues locking into the magazine well when the bolt is forward. It was originally designed to be inssrted with the bolt to the rear.
The mag will only seat and the bolt close properly loading a round if the bolt is locked open with the chamber completely empty. Otherwise, you will not be able to seat the mag with 31 rounds in the mag well. That’s why we load 30 and back one off each magazine for a total of 29.
The reason EVERY magazine has a little extra space because once you load the SPECIFIED amount of rounds the manufacturer says it's supposed to hold the rounds are supposed to push down a little when you load the magazine in closed bolt weapon systems. If you load that extra round you're going have a hell of a time loading in your magazine on a closed bolt. Unless it's locked to the rear or you hold it open it's still prone to malfunctions because the recoil spring doesn't have enough dick behind it to push the bolt forward and that round out of the magazine from the extra tension of there being an extra round in there.
Since I rarely get into social situations where max round count is a priority, I've usually just gone with 25 rounds per mag. It might make it easier on the mag, and it allows for five, five shot groups from the bench, and works out (usually) even for most cartridge boxes. Such as 100, or 50 round boxes, and also four loaded mags from five twenty round boxes. Helps keep things neat.
Those commenting that the reason why you could cram the 31st round in it is to allow the mag to be inserted with the bolt closed. People used to download one round so it would reliably seat and lock on a closed bolt (combat reload vs tactical reload). Honestly many of your videos are not fully researched and often have bad info
Situation: you've just ran 5 mags cyclic on burst. You load your 6th magazine and think how nice it would be if your m4 was belt fed and auto. You hit the bolt latch and feel the bolt jump forward but somethings off. You squeeze the trigger and hold it, nothing. Your bcg, upper receiver and the locking lug were getting sprayed with hot gas full of carbon and when everything got hot and dirty the drag on the round going into the chamber and the round that took its place on top in the magazine worked together to prevent that 31st round from entering the chamber. Your forward assist does nothing but marr the side of the bcg because it shouldn't get stuck that far back. Those panicked seconds when your rifle fails to function because of something stupid could be your last. Maybe loading your magazines to maximum capacity increase the likelihood of feeding failures. Maybe it doesn't matter and situations like I described never happen because of over-full magazines. If you believe you'll never be in a situation that requires a reliable firearm, well, bless your heart.
30 rounds is the spec so that they are not jammed in there too tightly for the action of the rifle to get a round out and in position properly. It is far better to just use 30 than to risk it not firing in any AR with less than stellar performance. You may also be putting excess pressure on the feed lips of the magazine if it sits loaded, especially like that, and cause a misfeed that way. Just keep to a reliable 30 rather than trying for a possibly unreliabe 31. After all, the point of being able to switch mags is to relaod quickly if needed.
Yes you can fit 31. Now try to place the mag inside the rifle. Will not lock in place unless you beat it in. With bolt closed obviously. And doesn't want to strip off the first round when attempting to load
The additional travel isn't for adding one more round. It's to allow the fully loaded magazine to fully seat on a closed bolt. Older mil spec mags didn't have the extra travel so they were typically downloaded to 28 or 29 rounds to achieve the same result.
Not gonna lie, I bought an $1,100 AR, ran all gen 3 magpul had no problems. They 2nd I loaded up and used a gen 2 magpul mag, problems ensued. But yes, the gen 3 window mags can run 31. Love Magpul products !
This is possible because you need "wiggle room" when loading a mag into an AR / M4 with a closed bolt. You need some give as the rounds will hit the bottom of the closed bolt carrier. The reason it hits the bottom is it has to strip a round from the mag each time, therefore they need to sit "up" a little. Taking away this "give" will potentially cause problems seating the mag with a closed bolt.
Did this and it jammed the case in the barrel the extractor wouldn’t pull it. Got home from the range and shoved a cleaning rod down the barrel. Wouldn’t come out. I had to fully disassemble to the barrel only. Chunk by chunk I had to pull that case out. Fluke in the cartridge? Or issue from over feeding the mag?
Heard about the VR issues with these cards abd u just got the XFX MERC310 7900 XTX as I figured it should be nearly 100% fixed now. Upgrading from EVGA 3080 FTW3 12GB but also getting a 9800X3D (upgrade from 5900X) when they get back in stock. Glad you haven't had issues so this solidified my choice. Your issue with Substance is a concern for me but I have a laptop with a 13900HX and mobile 4090 so I may just have to do textures on that. Just running DDU should be fine I hope seeing as I don't know where my windows key is lol Thanks for the video and maybe I'll run into you in VRC someday!
For people who do this. Sometimes your bolt won't go forward with the 31st round in. Or it will not ceit right into the magwell and drop the mag when you rack the first round. All this hassle isn't worth 1 extra round
You can fit 31 in almost any 30rd AR mag if you force it, but honestly you should only load 29. A mag with 30-31 in it will almost never fully seat in the mag well with a closed bolt under normal pressure. You have to slam it home really hard, or you’re going to lose your mag after the next round you first. These are things you don’t want to have to remember in a firefight. Load your mags so they go in your rifle as easily as possible whether the bolt is open or closed, which in a P mag is 29 rounds.
I went to a training recently where they explained. That the only situation you should keep you Pmags loaded, is if you keep that they come with on top. Tests have shown pmags with 30rounds stored without the cover, causes the lips to flare out.
This is also true of old Colt 30rd metal mags. Putting an extra round in the mag can cause feeding issues, it can cause the spring coils to jump over themselves in tighter springs and get stuck, or it can damage the follower. But it can be done.
you can overload past labeled capacity but that mag will not seat in the magwell. nor will it feed from dropping the bolt, 28-29rds max capacity for best reliability
When you try to put your mag in your gun, that extra round will not allow to catch the mag for the mag release notch and even stress the mag spring and could cause malfuntions when feeding...
Grunts and Vets learn 28 rounds to prevent double feeds, jams, and wear on the mag spring. More rounds sound "smart" until you realize in an actual war that most of your time is spent in the movement to contact. That puts the spring on constant pressure. Dirt and small rocks can get jammed in spaces that can make a magazine irrelevant at a crucial moment. Give me 28 rounds over 0, from 31 round jammed mag.
That "extra" room is why you don't need to download modern p-mags for truly reliable feeding like some other magazine designs. It also gives dirt and debris a little room so they don't easily impeed function.
This is not a secret and hasn’t been since they came out. You just can’t reliably seat the mag without excessive force with more than 30 rounds in the mag. In most cases, you can actually fit 32 in them (variance in plastics, temperature, spring wear, etc. do apply), but with 32 it is almost impossible to seat the mag into the rifle without a tremendous amount of force or the bolt pulled back exclusively. They are still a 30 round mag, tolerance is a thing though.
Its so you can load a full 30 magazine into the ar. Thats space to allow the mag to push in without the bolt open.....Also allows room to charge the weapon without binding the bolt, just load 30 max....
PLEASE DO NOT OVERFILL YOUR MAGAZINES. The thing he doesn’t talk about here is, with that 31st round in the magazine there is so much tension on the magazine spring you’re almost guaranteed to have feeding issues because the bolt cannot easily push the round from the magazine into the chamber because there is too much resistance
That 'space' which so-called allowed you to put in the 31th round in the mag, is supposed to allow you to insert the mag into the weapon with its bolt forward. Now that the 'space' has been occupied, you will have to insert the mag into the weapon with the bolt behind.
You better have the BCG locked back if you plan on getting the mag all the way into the magwell and locked. There’s a reason they have a little slack when full. With the bolt closed, that mag won’t fit.
Just buy some 42 and 60 round mags. Because of the ammo shortage during Covid, and my stolen FAL and AK was long gone too, bought an SKS for an emergency back up. It came with a variety of mags in both metal and polymer/plastic. A couple of the 30 round mags fit 32 or 34 rounds comfortably. I don't remember the bolt locking to the rear, so reloading kind of bites and makes me miss the other rifles more and can't beat the AR. The FAL had the best range, mount with a scope that didn't interfere with the iron sights, pretty accurate too. As long as fired one round at a time, recoil was basically non-existant and the barrel didn't climb like my old AK would want or old M16s on full-auto depending on which one and the way of holding them. For the M16s we only ever had 20-rd and 30-rd steel GI mags, only took 20 and 30 respectively. Found some mags in my stuff and they had been loaded for 20+ years. The 20 rounders, after emptying and cleaning, I broke one that wasn't really meant to be disassembled or perhaps the locking tabs were just worn out. Another had a shot spring, but I believe when they say that won't harm a Spring, but in reality that mag was probably produced for Vietnam and saw a lot of years of qualifications and other uses such as with MILES gear. That was the only time that I ever had a magazine spring issue.
That extra room isn't for additional rounds! The extra space is for the mag covers. When you use the covers, it takes pressure off the feed lips. 31 rounds won't lock consistently on a closed bolt.
The gen 3 pmags worked out the “downloading” habit. All they really changed about the mechanics was allowed the follower on 30 rnds to go down a little farther incase of top off. This allowed you to top off and not have to fight against the follower and have to download mags to make it work. Hope this helps :)
I wouldn’t add an extra bullet for the fact that you can get a double feed and a jam. I also keep 28 rounds instead of the 30 rounds as they were designed because I keep around a dozen magazines always loaded and to protect the spring. I know that it was an issue with the US Army metal magazine in the past and that they fixed the spring but I am not taking a chance.
Of course you can if you don’t mind putting more tension on the spring loader. The wear and tear will be resultful in couple months. Now you can actually have one extra round by putting it in the chamber before loading up the magazine, it just a matter of how much trust you put into your rifle’s safety and your marksman behaviour. Again this is a compromise between safety and practicality, if you’re in a war zone or during a civil war maybe these tips could really make a difference. Stay smart, stay vigilant.
30 rounds leave room for the rounds to compress when putting mag in an AR with a closed BOLT. Try inserting the magazine with 31 rounds, it might not seat correctly 🤷🏻♂️
Yes, yes fantastic advice on how to wear your springs faster and perfect for FTF training on your last 5 rounds. For real application I would not unless you plan to immediately fire said magazine. My 2 cent
Now, with a closed bolt, try and insert the mag. Once the mag is inserted, if you can, lets see if you can pull the charging handle. Most of the time with my ar308 can't even put the normal round count. Why? The mag needs to have about half a thumbnail of play so that bolt is still functional. This is my experience, your mileage may vary.
The "31st" round space is for the bolt when you insert the magazine on a closed bolt. Don't do this unless you know you are going to shoot to empty and your bolt is gonna lock back
"Just because you can doesn't mean you should" is applicable in this situation.
Yes
The reason you can is so you won’t struggle as much to load it into your rifle with a closed bolt carrier
Haven't struggled yet, the metal GI mags were something else tho.

This is true.
Many high cap magazines, even with pistols, are far more reliable by downloading the number of rounds by 1.
Thus as you've said, by them making the magazine able to hold another round then what you plan then to hold, allows for a higher reliable use of them.

@Shuck-Shick-Blam In the Marines I always loaded to 29 rounds. Some guys would do 28. As you said, this was to ensure easy mag insertion and proper weapon function every time.
But please, let's stop calling them hi-capacity mags. That's a gun grabbers term. 30 rounds in an M-16 or AR-15 is a STANDARD CAPACITY magazine.
Your bolt carrier: "come outside, I just wanna talk, no no, I just wanna talk"
Yes the mag can take 1 more bullet, but does the rifle function correctly with no malfunctions or problems with the magazine loaded pass the factory magazine capacity???
Malfunction, tried multiple times, either a double feed or some nonsense up to leaving 1 in the chamber after 30 round burst. Just don't.
One of the problems with magazines is the plastic sides where the round presses against.
Over time they can deform with the constant spring pressure.
For this reason these mags come with a dust cover that presses the round down off the sides relieving the tension.
That "hidden trick" isn't extra space to force another round in, it's extra space to afford you the ability to preserve the side lips and keep your mags running smoothly for longer.

The extra space is for better feeding, less stress on the feed lips, and it allows you to put their dust covers they come with on when the mag is full.
And the dust covers are designed for more than just keeping debris out. They're actually designed to keep pressure off the feed lips during storage. And an added feature is that the dust covers make the mag be considered an enclosed container, which means you can leave your mags loaded when you fly, only if you have a dust cover on it
There's a little extra space so that you can seat the mag on a closed bolt.
Why do you need a magazine loader you pansy
Used to come with
@@JcikokalolI noticed this today. At the local gun store, none of them came with the dust cover
THE QUESTION IS, WILL THE MAGAZINE OPERATE PROPERLY WITH THE THIRTY FIRST ROUND.
Now try to feed with 31 in.
It'll stop the bolt every time 😂
My metal mags can only hold 29, or it gets stuck
Possible if you have an ambi bolt catch
@f.e.oeeorch581 it won't at all when the bolt is closed, which is what he's talking about.
Multiple reasons not to do this.
1. Spring/feed lip damage. 30 is fine but already debated heavily. Dont do 31
2. Mag seating. 30 is fine but sometimes needs a slap. Dont do 31
3. Round count. Only a 3% increase in round count isnt worth the trouble. If you want more, carry another mag.
4. Odd numbers. 30 is a good number. Theres a reason they arent designed to hold 27 or 31 rounds. Its more work to keep track of your round count.
5. Loading. Loading 31 is more effort and some magazines wont even fit them in.
''so I recently learned something useless that doesn't actually work reliably rifle to rifle''
That space in the magazine that allows you to add that one extra round is specifically designed so you can seat the magazine on a closed bolt effortlessly. Don’t add the extra round.
Exactly. I thought I had a major issue when racking one to the chamber until I realized I overloaded the mag with an extra round by not paying attention. and then prior to that, I really sat there wondering why it was so hard to catch on the mag release?! 🤦♂️
Lol, this is why you have short bus commandos telling everyone they need to download thier mags to 29....the overloaded thiers a few times and found the issue went away.
@@rantional8180 All they gotta do is count.
@CollKill2 lol, that's obviously asking too much....and really you don't even really need to count in most cases, it's just a box and a half, 3 boxes of 20 rounds is 2 loaded mags. Lol
When the show was canceled, Alan Tudyk removed the button from the control panel, that was supposed to recall the shuttles. Joss Whedon promised the cast and crew that he was going to work on getting the show picked up by another network. Tudyk gave Whedon the button, telling him, "When you get your miracle, hit this.

*feeding issues*
“Lemme introduce myself” 😁
Oh you thought that was a funny comment huh... Cornball dork
When storing your POLYMER mag with no metal lip, it is recommended not to put the full capacity. It's better to put 1 or 2 less so as not to damage the lip. Also, having less 1 or 2 rounds, will have a better feeding function.
Yeah like everyones saying, its designed to take 30 so you can still insert in on a closed bolt.
“Hi guys, watch me start teaching people to break all the lips of their mags… ready.. get set…. DUHhhhh.”
Firstly, those are two different generations of pmag
Secondly, this is dumb, the ability to add an extra round is due to the mag being designed to seat easily in a weapon with a closed bolt.
This is a good way to wear down and screw up your mags. Drop one like this and the chance of a round falling out is high.
Store them like this and you risk breaking feed lips.
What the fuck is the difference between the generations I have one twos and threes all of them hold 30 rounds all of them shoot exactly the same none of them have any issues I don't know what the fuck you guys are all talking about
Best reply here
That extra room is there by design to load a 30 rounder into a closed bolt. If you put the 31st round there’s not enough room for it to compress and lock in. 30 rounders are just that….30 rounders
I smell a jam.
...this guy's intestines be like, "Hey, there's more space for food in the appendix...."
Now try inserting it into the mag well. My guess is it’s too wide?
Nothing a good hard “whack” can’t fix with the bolt open!😂
I feel ya dog, I don’t even watch these fools channels anymore. It’s all a money bag. Kinda like the Netflix special that was just on 😂😂😂
You can do it with every mag besides the metal magazine I have a ton of every type of mags I have a couple few mft mags magpull random polymer magazines and thy all fit 31 but the bad thing is, it's hard to put the magazine in the gun on a closed bolt
I was going to say it but yeah I’m happy that there’s a lot of educated gun owners out there that already nailed it.
1 in the chamber and 29 in the mag is what the new generation does and it works well. If your mag doesn’t work, make sure you have it marked and get it taken care of.
Dont use 31 rounds. The reason you can put 31 rounds in it is because the old usgi mags had to be downloaded by 1 round to make a 29 round mag because there wasnt enough give to insert a mag on a closed bolt. To fix this most modern AR mags are actually 31 rounders, because you would want one less then it can hold to have enough play to insert on a closed bolt.
This is patently false. A full 30 in a GI mag inserts perfectly fine on a closed bolt. If you’re having problems inserting a full mag I suggest getting stronger
@JazzIs4urSoul Modern USGI mags, yes. Old school USGI mags no, they don't fit, and they cause problems
Booooohhhyahahhhh
@@JazzIs4urSouldoesn’t require strength it’s literally made to be inserted fully loaded so if you gotta be “strong” or slam that mf in there something is wrong with the magazine or magazine catch itself
@@jeremiah0628 I’m saying it’s literally made for it. If you can’t overcome the minute amount of spring pressure compressing the full 30 you’re a bitch
You can fit 64 rds in a 60 rd mag, sometimes even 65 but at that point it feels like the mag is going to explode, or the ammo. 😅
I accidentally put 31 in without realizing, and it wasn't cycling in my rifle until I took that extra out
The extra space is meant to resolve any mag seating issues with the bolt forward. With the bolt forward, this mag loaded to 31 will not seat no matter how hard you smack.
That's for all of those 29 round kids that think you can't have 30 rounds in it.
I thought we were just doing that to get around bullshit
A fully loaded 30rd mag still requires more force to seat properly when the bolt is closed.I only load 29 rounds for consistency, but end of the day it’s all preference.
Always load even numbers, such as 28 in a 30 rd mag or 18 in a 20 rd mag, or 26/ 16 and down, so as to have the round on the right side of the lips for the top round in the mag for a reliable strip and chambering @joshuatomasian6202
@joshuatomasian6202 Barely any extra force. Go do some push-ups my guy. Or get better mags... or a better rifle.
Putting 31 rounds in that magazine may make it difficult - if not impossible - to insert the magazine into the rifle with the bolt in the forward position. To avoid unpleasant surprises during an emergency, I'd recommend that you only load 30 rounds into the magazine.
No, you cannot, you need that extra spring play for reliable operation. This is dangerous and will lead to gun malfunctions. Please take this down for safety reasons.
That’s for spring slop! You don’t want your mag bottomed out fully loaded. It’s a matter of built in volume.
😂😂😂😂 I guess you don’t understand how springs work
so you have heard people say that you should only load 28-29 rounds in a 30 round mag for reliable feeding. they are talking about putting the mag in the gun, with 30 rounds in an older style 30 round mag, you would really have to slam the mag in with some gusto most of the time to get it to seat.
Magpul has added a bit more clearance (which allows a 31st round to fit) so that you can load 30 rounds, and still put the mag in reliably without having to slam it home every time. its nothing to do with "feeding" or them marketing a 31 round mag as a 30 round mag, the space is there for a reason and its not to put a 31st round in it.
When it advertises for 30 rnd magazine, it only 30 rnd. not 31. You are just creating confusion to your content and misleading to your followers.
When people’s guns won’t load a round or they can’t load the magazine into the gun when needed, it will be their own fault for listening to this guy 🧐😏
@@TooManyChoices1yep exactly
I agree with many here. I have all mine with 28 rounds in them so i have way less chance of feed issues. Getting 2 rounds stuck very hard in there twice had me change a few things a few years ago. Nearly impossible to get it operable again without a brass rod. I dont want to cause a condition in the feild that causes tools needed that i dont keep on me.
Uses cheater loader to load 30 rounds then proceeds to not use cheater to force in round 31. Brilliant.
How is it a cheater?
Speed loader, load assist, whatevs. My God you’re sensitive.
Sensitive? I only asked a question, about how it was cheating to use a round loader
@joestuckey3290 sounds to me like youre annoyed, not sure why but taking it out on me I doubt would help
Look bruh, my point is I called it a cheater for lack of a better name coming to mind at the moment I made the original comment. Then, to appease your sensitivities, I clarified it as a round loader, speed loader, etc. Now you’re just being petty. I really didn’t mean to imply you are a cheater by using one. Lastly, I fully reject the implication that I am annoyed. I’m just trying to educate you on how synonyms can be applied in the English language.
The extra travel is so you can insert 30 round mag on a closed chamber. Also 31 round loaded mags could lead to critical compression of the spring leading to earlier spring failures
It used to be recommended to only put 28 rounds in 7.62x39R magazines to reduce the spring fatigue.
Springs don’t get “fatigued”. There’s videos explaining this, and the physics and engineering behind it. People would only do 28 or 29, because doing 30 would cause poor seating of the mag in the lower. Due to the 30th round preventing slack in the spring to prevent the mag from fully inserting and locking into place. Hence why they came out with this “31 round mag”. Allowing for a true 30 round count mag.
@@shanktrujank1294 That makes sense. Both reasons are probably true because springs do deteriorate. But it takes a long time and doesn't happen to everyone.
762x39 rimmed? thats not a cartridge buddy...
@@shanktrujank1294😂😂😂😂 did you even bother to read what you wrote😂 Mr misinformation 😂
There is a caveat here, yes you can fit 31 rounds in a Pmag, but if you’re bolt carrier is forward you can’t properly seat the magazine. The extra give that happens with only 30 rounds is room needed for the bolt carrier.
The extra space is to allow inserting a fully loaded magazine into the mag well with the bolt forward. USGI magazines, when fully loaded, have issues locking into the magazine well when the bolt is forward. It was originally designed to be inssrted with the bolt to the rear.
31 = feeding issues. Some download their mags to 29 to prevent this. Do not do this.
The mag will only seat and the bolt close properly loading a round if the bolt is locked open with the chamber completely empty. Otherwise, you will not be able to seat the mag with 31 rounds in the mag well. That’s why we load 30 and back one off each magazine for a total of 29.
The reason EVERY magazine has a little extra space because once you load the SPECIFIED amount of rounds the manufacturer says it's supposed to hold the rounds are supposed to push down a little when you load the magazine in closed bolt weapon systems. If you load that extra round you're going have a hell of a time loading in your magazine on a closed bolt. Unless it's locked to the rear or you hold it open it's still prone to malfunctions because the recoil spring doesn't have enough dick behind it to push the bolt forward and that round out of the magazine from the extra tension of there being an extra round in there.
Since I rarely get into social situations where max round count is a priority, I've usually just gone with 25 rounds per mag. It might make it easier on the mag, and it allows for five, five shot groups from the bench, and works out (usually) even for most cartridge boxes. Such as 100, or 50 round boxes, and also four loaded mags from five twenty round boxes. Helps keep things neat.
Those commenting that the reason why you could cram the 31st round in it is to allow the mag to be inserted with the bolt closed. People used to download one round so it would reliably seat and lock on a closed bolt (combat reload vs tactical reload). Honestly many of your videos are not fully researched and often have bad info
Situation: you've just ran 5 mags cyclic on burst. You load your 6th magazine and think how nice it would be if your m4 was belt fed and auto. You hit the bolt latch and feel the bolt jump forward but somethings off. You squeeze the trigger and hold it, nothing.
Your bcg, upper receiver and the locking lug were getting sprayed with hot gas full of carbon and when everything got hot and dirty the drag on the round going into the chamber and the round that took its place on top in the magazine worked together to prevent that 31st round from entering the chamber. Your forward assist does nothing but marr the side of the bcg because it shouldn't get stuck that far back.
Those panicked seconds when your rifle fails to function because of something stupid could be your last. Maybe loading your magazines to maximum capacity increase the likelihood of feeding failures. Maybe it doesn't matter and situations like I described never happen because of over-full magazines. If you believe you'll never be in a situation that requires a reliable firearm, well, bless your heart.
30 rounds is the spec so that they are not jammed in there too tightly for the action of the rifle to get a round out and in position properly. It is far better to just use 30 than to risk it not firing in any AR with less than stellar performance. You may also be putting excess pressure on the feed lips of the magazine if it sits loaded, especially like that, and cause a misfeed that way. Just keep to a reliable 30 rather than trying for a possibly unreliabe 31. After all, the point of being able to switch mags is to relaod quickly if needed.
Overloading the magazine is the best way to keep it from loading on a closed bolt. Is an extra round worth that complication?
Will it function correctly now tho or is there to much pressure to pick up the round
Spring killer. Now feed the mag in the well with a closed bolt. Does she slide in easy or does it need pushed?
The follower spring is meant to have enough room to seat a fully loaded 30-round mag on a closed bolt. Same thing applies to the 25-round .308 Pmags.
Yes you can fit 31. Now try to place the mag inside the rifle. Will not lock in place unless you beat it in. With bolt closed obviously. And doesn't want to strip off the first round when attempting to load
The additional travel isn't for adding one more round. It's to allow the fully loaded magazine to fully seat on a closed bolt. Older mil spec mags didn't have the extra travel so they were typically downloaded to 28 or 29 rounds to achieve the same result.
What's the trick? That's just removing the extra 'slop' that ensures you can fully seat a fresh mag with a closed bolt.
Not gonna lie, I bought an $1,100 AR, ran all gen 3 magpul had no problems. They 2nd I loaded up and used a gen 2 magpul mag, problems ensued. But yes, the gen 3 window mags can run 31. Love Magpul products !
This is possible because you need "wiggle room" when loading a mag into an AR / M4 with a closed bolt. You need some give as the rounds will hit the bottom of the closed bolt carrier. The reason it hits the bottom is it has to strip a round from the mag each time, therefore they need to sit "up" a little. Taking away this "give" will potentially cause problems seating the mag with a closed bolt.
Did this and it jammed the case in the barrel the extractor wouldn’t pull it. Got home from the range and shoved a cleaning rod down the barrel. Wouldn’t come out. I had to fully disassemble to the barrel only. Chunk by chunk I had to pull that case out. Fluke in the cartridge? Or issue from over feeding the mag?
Heard about the VR issues with these cards abd u just got the XFX MERC310 7900 XTX as I figured it should be nearly 100% fixed now. Upgrading from EVGA 3080 FTW3 12GB but also getting a 9800X3D (upgrade from 5900X) when they get back in stock. Glad you haven't had issues so this solidified my choice.
Your issue with Substance is a concern for me but I have a laptop with a 13900HX and mobile 4090 so I may just have to do textures on that.
Just running DDU should be fine I hope seeing as I don't know where my windows key is lol
Thanks for the video and maybe I'll run into you in VRC someday!
Biggy Smalls said it best "don't fill them clips to high, give them bullets room to breathe". Don't want them to jam on you
For people who do this. Sometimes your bolt won't go forward with the 31st round in. Or it will not ceit right into the magwell and drop the mag when you rack the first round. All this hassle isn't worth 1 extra round
You can fit 31 in almost any 30rd AR mag if you force it, but honestly you should only load 29. A mag with 30-31 in it will almost never fully seat in the mag well with a closed bolt under normal pressure. You have to slam it home really hard, or you’re going to lose your mag after the next round you first. These are things you don’t want to have to remember in a firefight. Load your mags so they go in your rifle as easily as possible whether the bolt is open or closed, which in a P mag is 29 rounds.
I went to a training recently where they explained. That the only situation you should keep you Pmags loaded, is if you keep that they come with on top. Tests have shown pmags with 30rounds stored without the cover, causes the lips to flare out.
This is also true of old Colt 30rd metal mags. Putting an extra round in the mag can cause feeding issues, it can cause the spring coils to jump over themselves in tighter springs and get stuck, or it can damage the follower. But it can be done.
Don’t put 31 rounds in. The extra space is designed to allow you to correctly seat the magazine in the rifle’s magazine housing/body.
you can overload past labeled capacity but that mag will not seat in the magwell. nor will it feed from dropping the bolt, 28-29rds max capacity for best reliability
You may damage your spring doing that or have trouble installing it. Is it really worth it for an extra round?
When you try to put your mag in your gun, that extra round will not allow to catch the mag for the mag release notch and even stress the mag spring and could cause malfuntions when feeding...
im just wondering if when you try and load will the first one spit up two bullets causing a jam
Grunts and Vets learn 28 rounds to prevent double feeds, jams, and wear on the mag spring.
More rounds sound "smart" until you realize in an actual war that most of your time is spent in the movement to contact. That puts the spring on constant pressure. Dirt and small rocks can get jammed in spaces that can make a magazine irrelevant at a crucial moment. Give me 28 rounds over 0, from 31 round jammed mag.
Can you feed the mag in your AR on a closed bolt with 31? I wouldn’t trust this as a viable option. The extra space is so it fits into your gun.
I've encountered feeding malfunctions at 30 rounds with some mags. Keep it around 28-29 and you won't have issues.
That "extra" room is why you don't need to download modern p-mags for truly reliable feeding like some other magazine designs. It also gives dirt and debris a little room so they don't easily impeed function.
This is not a secret and hasn’t been since they came out. You just can’t reliably seat the mag without excessive force with more than 30 rounds in the mag. In most cases, you can actually fit 32 in them (variance in plastics, temperature, spring wear, etc. do apply), but with 32 it is almost impossible to seat the mag into the rifle without a tremendous amount of force or the bolt pulled back exclusively. They are still a 30 round mag, tolerance is a thing though.
Its so you can load a full 30 magazine into the ar. Thats space to allow the mag to push in without the bolt open.....Also allows room to charge the weapon without binding the bolt, just load 30 max....
PLEASE DO NOT OVERFILL YOUR MAGAZINES. The thing he doesn’t talk about here is, with that 31st round in the magazine there is so much tension on the magazine spring you’re almost guaranteed to have feeding issues because the bolt cannot easily push the round from the magazine into the chamber because there is too much resistance
That window is cool.
You can fit 31 because the cover for the mag pushes the rounds down to keep tension off the feed lips during storage.
That 'space' which so-called allowed you to put in the 31th round in the mag, is supposed to allow you to insert the mag into the weapon with its bolt forward. Now that the 'space' has been occupied, you will have to insert the mag into the weapon with the bolt behind.
Faramir "I can only load 31 rounds"
Denethor "Boromir could have shoved 32 rounds in"
You better have the BCG locked back if you plan on getting the mag all the way into the magwell and locked. There’s a reason they have a little slack when full. With the bolt closed, that mag won’t fit.
What happens if you cut off 1" of internal spring? Would the spring still have the force it needs to push the cartridges up?
Just buy some 42 and 60 round mags. Because of the ammo shortage during Covid, and my stolen FAL and AK was long gone too, bought an SKS for an emergency back up. It came with a variety of mags in both metal and polymer/plastic. A couple of the 30 round mags fit 32 or 34 rounds comfortably. I don't remember the bolt locking to the rear, so reloading kind of bites and makes me miss the other rifles more and can't beat the AR. The FAL had the best range, mount with a scope that didn't interfere with the iron sights, pretty accurate too. As long as fired one round at a time, recoil was basically non-existant and the barrel didn't climb like my old AK would want or old M16s on full-auto depending on which one and the way of holding them. For the M16s we only ever had 20-rd and 30-rd steel GI mags, only took 20 and 30 respectively. Found some mags in my stuff and they had been loaded for 20+ years. The 20 rounders, after emptying and cleaning, I broke one that wasn't really meant to be disassembled or perhaps the locking tabs were just worn out. Another had a shot spring, but I believe when they say that won't harm a Spring, but in reality that mag was probably produced for Vietnam and saw a lot of years of qualifications and other uses such as with MILES gear. That was the only time that I ever had a magazine spring issue.
That extra room isn't for additional rounds! The extra space is for the mag covers. When you use the covers, it takes pressure off the feed lips. 31 rounds won't lock consistently on a closed bolt.
The gen 3 pmags worked out the “downloading” habit. All they really changed about the mechanics was allowed the follower on 30 rnds to go down a little farther incase of top off. This allowed you to top off and not have to fight against the follower and have to download mags to make it work. Hope this helps :)
31:50 People will generally pick tyranny over anarchy. It's why we get things like monarchs after our age as a hunter-gatherer society.
I wouldn’t add an extra bullet for the fact that you can get a double feed and a jam. I also keep 28 rounds instead of the 30 rounds as they were designed because I keep around a dozen magazines always loaded and to protect the spring. I know that it was an issue with the US Army metal magazine in the past and that they fixed the spring but I am not taking a chance.
Of course you can if you don’t mind putting more tension on the spring loader.
The wear and tear will be resultful in couple months.
Now you can actually have one extra round by putting it in the chamber before loading up the magazine, it just a matter of how much trust you put into your rifle’s safety and your marksman behaviour.
Again this is a compromise between safety and practicality, if you’re in a war zone or during a civil war maybe these tips could really make a difference.
Stay smart, stay vigilant.
*insert video of a cop trying to load a "31" round mag on a closed bolt and failing horribly*
I would be cautious about this. What's the damage caused to the spring?
30 rounds leave room for the rounds to compress when putting mag in an AR with a closed BOLT.
Try inserting the magazine with 31 rounds, it might not seat correctly 🤷🏻♂️
Yes, yes fantastic advice on how to wear your springs faster and perfect for FTF training on your last 5 rounds. For real application I would not unless you plan to immediately fire said magazine. My 2 cent
Now, with a closed bolt, try and insert the mag. Once the mag is inserted, if you can, lets see if you can pull the charging handle. Most of the time with my ar308 can't even put the normal round count. Why? The mag needs to have about half a thumbnail of play so that bolt is still functional. This is my experience, your mileage may vary.
The "31st" round space is for the bolt when you insert the magazine on a closed bolt. Don't do this unless you know you are going to shoot to empty and your bolt is gonna lock back
