CMMG .22LR Conversion Kit Overview
Вставка
- Опубліковано 15 сер 2024
- In this video we take a dive into the .22LR Conversion Kits. These allow you to convert your .223/5.56 chambered AR to shoot .22LR.
Make sure you choose the right one as there's also left handed variants and one designed specifically for our Mk57 (5.7x28) upper.

Just came here to say: CMMG, you guys knocked it out of the park with this product. I have gotten 10x the CQB practice in thanks to this. I’ve used even the cheapest .22 LR ammo in it, from Herter’s, to Remington and Winchester. Absolutely boss engineers over at CMMG.
It would be epic if you come out with a 30 round mag to better mimic standard ar mags.
Please correct me if I'm wrong.
I believe the reason they use a 25rd mag, is because that's all you can fit in a single file, in a magazine with the dimensions of a standard 30rd AR mag.
223 is wider than 22, but it's also rimless (and fairly cylindrical) which is perfect for double stack mags.
22lr is smaller, but it has a huge rim that has to be managed, the internal dimensions of the CMMG mags do a remarkable job at this, while being confined to the outside dimensions of a standard GI AR mag (they even put the lines on it)
If they wanted to stick 5 more rounds in the mag they'd have to 1: make the mag about ¾" to 1" longer to accommodate the rounds and the extra spring length to push all of them up. This can make the mags not compatible with some mag pouches, making training, and storage slightly more difficult.
Or 2: re-engineer all the internals to fit a stack and a half profile, the internal channel would have to be widened and geometrically modified, same with the spring, it would have to be modified to fill the channel and prevent snakeing, also the follower would have to be changed from a push top to a tilted style to guide the first round into a left-right pattern.
In the end you'd have a much more expensive and probably less reliable 30rd 22lr mag, that can fit in standard AR pouches, and that more than likely ain't gonna sell well, because *_"why buy 1 30rd mag? When I can buy 2 25rd mags."_*
Again please do correct me if I'm wrong.
Besides quality 22lr comes in 50rd &100rd boxes, and 4 full mags make 100 square rounds, it's mathematically perfect.
One of my favorite things about my conversion is being able to shoot .22 through a faster twist 5.56 AR barrel. It stabilizes the Aguila 60 grain SSS .22lr very nicely, and is awesome to shoot suppressed.
I wish I could find more of the SSS I have 2 boxes left and refuse to shoot em. Lol
I also tried the 60gr aguila, it is the most accurate for me.
@@BurrowsNE man I wish I could find more of that I've got two boxes that I refuse to shoot because I have not seen it anywhere!
With a 1:7 13” barrel what kinda distance could you expect with these 60gr .22?
I plan to use it for steel matches but there’s a few special .22 only matches that sound high speed enough to me that go out to hefty distances some of them even 230yds.
I figure a 5.56 barrel probably won’t be able to reach those distance? What ab the 60gr ammo??
@@Marksman5147 I think any 22lr is going to be dropping like a rock at that distance. But a 60 grain at 1000 fps will certainly have an advantage over a 40 grain at 1000 fps. I’ve shot 300 yards with a 40 grain CCI standard velocity (1050 fps I think) and the holdover was about 15 feet to hit a full size silhouette.
I love the way he took it out at the end to show us nice touch
I bought one of these CMMG kits about 10 years ago for 25 bucks used in a shop. Came in a brown plastic box that was cracked with two steel 10 round mags. Worked fine in a rifle I put together. I later put a dedicated pistol together and reversed the gas block blocking the port omitting the tube to keep the gasses out of the upper. Stays a lot cleaner. I use several different plastic manufacturer mags in it no issues.
I love mine. Perfect for handling drills and just plinking. Also, everyone wants to shoot it.
Great product 👍
Just got mine,. this is the best weapon I ever had, the most beautiful, the most fun, the most appreciated by my friends also
Just picked on up. CMMG brand. This is so much cheap fun! No recoil, very quiet, and very accurate. It's my favorite mod I have
This man knows where of he speaks. I have 3 of these and they are a ton of fun and savings. I would recommend using CCI AR Tactical with them for optimum performance, but they do work with other ammo brands. Obviously I am a fan.
One of the best companies! I had a failure on the conversion while shooting suppressed full auto with my M16. CMMG sent a replacement part to repair the conversion, no questions asked, no receipt requirements or anything. And they are not afraid to express their faith. Absolutely great folks to deal with.
Done and done! Kit came and I converted my Banshee yesterday. Can't wait to hit the range!
I really like my conversion kit… runs buttery smooth and I’ve never had any failure to cycle or 22LR stovepiping that seems to be fairly typical on a lot of OEM 22LR guns or mags. Great investment and really fun to shoot.
So what about the barrel can the round bounce of the side of the barrel
@@LoneWolf23NNo,.223 and .22 have the same diameter projectile.
I got one of these about three years ago, with four magazines. I shoot 300 to 400 rounds every week, and it’s still going strong. The only thing I’ve had to do is replace the firing pin spring. I have one of those ultrasonic cleaners, I take the conversion bolt apart drop the pieces in the basket run it for about 20 minutes and it’s just like new.
I bought one for my son the Christmas of 2022, and he uses it every week as well.
Probably the best thing I bought for my AR by far.
Bought one a few months back and just installed it this weekend. Unfortunately, it was an absolute bust in terms of reliability.
From what I could surmise, the problem appears to be the magazines. My kit has the mags with the red feed ramps and removable bottom plate to access. These have a lot of slop in them when seated in the mag well, causing the ramp trajectory to feed bullets at a steep angle into the chamber leading to FTF. Once the first round fed, the problem would somewhat clear up but never was more than 80% reliable.
In contrast, my buddy also bought this kit, but his had different style mags that had orange feed ramps and six (6) screws to take them apart. His kit operated almost flawlessly right out of the box.
In troubleshooting, one of the things we did was swap mags, and sure enough that appears to have cleared the issue.
I contacted CMMG in hopes I could trade in my mags or at least have them send me the orange followers. Hopefully I hear back from them soon and get this fixed because I really want this kit to work!
Have same issue with "red" magazines. It defenetly do not works as it should at my PSA ar15.
Did support guys help you?
I reached out to CMMG customer service, and they got back to me in 3 days. The guy who helped me was great to work with, and after taking my information and issues I was having, he is sending me new mags.
However, he did say they would be the same Gen 2 style mags I already have (red followers with waffle texture). I don't know if it'll solve the issue, but we'll see. I'll report back once I function check them.
@mlrllama Thanks for reply! Got you!
I bought this set and had a ton of problems in my Ruger AR556, specifically failures to fully eject with the brass getting caught up in the ejection port. I did two things to resolve the issue and now it runs great. 1. Put a little fuzzy side velcro on the top front of each magazine to take up some of the slop, and 2. Purchased an aftermarket charging handle for this kit that does not have the long groove on the underside.
So, update on my kit:
CMMG sent me three new mags to try out. On first inspection the springs seemed more stiff than the originals, so I was hopeful this would solve it.
Unfortunately, it did not. Same feed issues as with original mags, even with sturdier springs. I even swapped out the factory springs with Bore Buddy replacements, to no avail. I also tried CCI Stinger ammo as well as Tac-X designed for AR-15/22 setups...no go. At this point, I'm convinced it's the loose fitting magazine in the mag well throwing off the feed ramps causing it to bind up.
I guess I'll try other mags at this point. I hear S&W 22 mags are stellar so might pick one up to see. Shouldn't be this annoying...
Have had a cmmg 22 conversion kit for a few years, great product guys

Everyone with an ar15 or ar pistol should buy one. I love mine!
Bought it 3 years ago finally tried it today. I highly recommend this purchase mie would only eat CCI STANGERS fortunately I have lot nothing else would work Federal armscor none of it so 20 cents a round not 7 with strangers 0 malfunctions no other ammo would feed
Try CCI AR Tactical rounds. They're about .08 a round everywhere.
Cmmg has the best customer service in firearm industry from my experience
Love this product, I have purchased 2 for me and 1 as a gift for my brother in law, he loves it. Saves me a bunch of money
Great to hear!
My experience is that these are jamomatics in any rifle with a mid length or longer gas system. Carbine length gas systems and under, they run like a dream. Now I just wish they'd build one in .22 WMR.
This is part of buying an AR15 in my view. A 100% must have for sure! You also should buy a Lightin' Grip speed loader.
Best kits ever!!! I give these out as stocking stuffers for Christmas, they are so great!
@@MrSoonermadman they are priced very well for what you get out of them! Its an amazing deal! If you live in SWFL, Yes i will.
They are awesome. I have a very old edition and the magazine WAS horrible to deal with, but two days ago cmmg told me how to fix that issue and now it drops like butter. I will definitely be picking up some of those newer mags for extra. My bolt still works flawlessly. Also, great idea as gifts! A true 2a supporter.
@@MrSoonermadman good to hear! Amen brother!! 2A all the way!!! I am anxious to try the new mags aswell, even tho i never had any problems with mine 🇺🇲🇺🇲🇺🇲
I have one and it runs great in a shot out m16 upper I picked up at scrap prices. Very reliable.
Great to have saved me big time 💲 training during cov id🇺🇲👊
Even more fun when suppressed! I have the Adam Arms piston kit on my MSR and it cycles the bolt with no issues. Using standard velocity 22LR the action and hitting the target is louder than the report of the shot.
I’ve had mine for nearly 20 years. There’s a lot of good reasons to use it. It’s your weapon, your optics, your charging handle, your trigger. Sort of think of it as dry firing on steroids
I'm watching this video because I'm planning on buying this next week and I'm just a little bit skeptical. I don't see how it's not going to damage the barrel but I'm here to learn
Just bought my 2nd one.many pluses.few minuses.really good for wearing in New parts in New builds. Thanks.
I've been thinking of going this way. One of the video;s I saw was to add a Presser Buddy and an insert on the charging handle. One is to take up slack in battery, and the other prevent gases from blowing back in your face. I did not notice when the video was made, so maybe the new stuff is already incorporated!
I’ve had a couple of these over the years and I love them.
Got one of these and love it, told two other guys about it and both were "really?" and went out and bought them.
Just got mine still in the package ready to get it out and try it
How was it?
Just got my first AR-15 yesterday. Looking forward to installing this first to learn and then to save some bucks practicing. I'll shoot some 223 and 556 from time to time but this kept me from needing to buy both the Z-15 and the M&P 15-22.
This what I SHOULD have done.. spent hundreds on ammo (.223/5.56) and feel like it was a “waste” as training was so limited and duration between sessions were so far apart. This should definitely help me out!
I bought this about a year ago, while it hasn't had any failures, I just don't use it that much. I'm not putting the product down or talking bad about it, I just wish I had gotten a 22LR rifle.
If your having trouble try adding an extra buffer, quarters or something to take up space in the tube and tighten the spring. It helps stop the spring from causing bounce back. Then get an extra charging handle and fill the back inch with hot glue that will help with powder burns. And don't run for crap I'm ati polymer
Great addition to my rifle..gives me a lot of hands on for cheap
I fell in love a lot harder when I got that cmmg conversion
I have only one regret about my CMMG Bravo .22LR AR-15 Adapter.
That regret is, "That I didn't invest in it a lot sooner than I did."
Member of an Indoor Caliber Restricted Range, where Center-fire rifle is prohibited. Nearest Outdoor Range is 2+ hours away. Buying CMMGs Adapter makes my AR legal for use at my club.
Our lanes are 60' long, and at that distance, accuracy is as good as any Semi-Auto 22 I own.
At the outdoor range, accuracy is still adequate out to 50-75 yards. At 100 yards, the groups start to widen up a bit more than the other semis I own.
Is it Match Grade Accurate? No, but neither is a stock 10-22.
If you own an AR in 5.56/.223, I highly recommend investing in CMMG 's Bravo Kit. Running a little Rimfire cartridge that costs $0.05 - 0.10 compared to $0.50 - 1.00+ per round means a lot more economical trigger time.
The only issue I had was some 6 or 7 year old Remington Thunderbolt ammo, and I blame that on the ammo. It's given me issues in my other .22 self loaders. That's why it's 6-7 years old. I don't buy Remington .22LR at all because it only works consistently in single shot or revolvers in my experience. Has a lot more fouling too. Mexico's Aquila ammo is better than Remington's.
bought one of these last week, can't wait to use it.
I've had mine for a few years now and these things shoot as about as good as any other semi-auto .22, other than maybe an accurized rifle. My favorite thing about it, other than it's accuracy, is that it allows me to shoot 2 calibers with one gun so I have more space for steaks and beers in the truck.
It's fun when it works. The most frustrating thing is, the kit is not consistent when it wants to work. Somedays I can go 500 rounds without a malfunction , but others I can't shoot 5 rounds without a jam.
Great explanation thank you
This runs great in my hoffman tactical made parts.
It's worth every penny!
I was so about to buy that upper receiver off ur website till I noticed the plastic deflector. Man wish yall kept that metal I would have ordered on the spot.
Okay I would like to know if this conversion kit changes the zero of the rifles sites red dot and iron?
Great question! Do you know the answer?
@@mnrodriguez well I used both and it doesn't change. The. 22lr and 5.56 stay the same.
@@russellleavitt4449 , good to know, thanks!!!
@@mnrodriguez anything to help
I wouldn't throw away the rubber protector..good to put on if you're keeping in your traveling bag or whatnot
i have one of the new kits, i dont know about it! first price was insane but i found it on PSA for like $160 with 3 mags(by the way are a pain to load), then spent shells keep getting stuck even with the special charging handle, a few failer to eject and after about 500 rounds holy crap is my gun dirty, looks like a 50 year old gun thats never been clean lol,
If you have a .22 conversion kit fitted to your AR can you use a .22 suppressor or do you have to use a .223 5.56 suppressor?
You can use a .22 supressor. Just don't shoot a .223 or 556 through it
The only thing this video really told me about this product is that it exist. Is it accurate? Is it reliable? Is it or isn’t it depending on the ammo? Idk but it exists 👍
Have one for a few years and never used it yet.
Good one, but you should say it won't work if someone got notched hammer, it isn't compatible. To make it work you need to replace hammer, or grind the notched one.
We specify that on the product pages. Sorry we forgot to mention it in the video as notched hammers aren't as commonplace anymore. Most manufacturers currently run rounded hammers.
I bought my kit a few years ago, it was buggy, the magazines fit lose in the well. Kept jamming, I had to add epoxy to them for a snug fit. Haven't used the modified magazines yet....
boonie packer better mag adapter, allows you to use s&w 22lr mags. i never have issues. also recommend using a 22lr charging handle and tacom pressure plug.
Great video. I am going to try to get a couple of those new mags. They look a lot better than the grey beast of a mag I have. Thanks again! Cmmg is an awesome company.
I have a question. Does this work with the AR 15 PSA Blem 556?
Mine doesn't like Winchester 36g golden bullets. It does 36g CCI Mini Mags just fine.
Are these full auto rated for binary trigger setups ??
How do you recommend maintenance of the conversion kit and barrel?
If CMMG were to make a .22lr conversion kit that replaces the bolt of a BRN-180 AR UPPER Then they will have truly become the big daddys of utilitarian useful hunting / defense & sport tools . As it is there CMMG .22LR adapter works way more dependably than a 10-22 . They have out done themselves. ¿ Please make a conversion kit for BRN-180 . Also would like to see a .22mag conversion kit for ar-15. & BRN-180 .? Imagine if you had a brn-180 & for some reason the piston system failed you could still use the rifle unaffected in .22lr . And in any 5.56 ar or brn-180 if a bolt lug broke or something like that gas rings ect , u should be able to use the .22lr kit unaffected by that .
If used with the Catch 22, will the newer magazine engage the catch?
Do the Paul Harrel, shoot until you have one round left. Drop mag, put in another and keep shootin'
I got one of the kits but discovered it's a pain with my side-charger. Wish I could use the kit easily.
If i simply start immediate actions slap that mag like a latina with attitude rack the slide like your pulling her hair will it cause issues? Basically every reload practice immediate procedures for a malfunction?
Mine was awesome
Now I need a .22 suppressor. Dang it!
😏🤭😂
Mines a single shot mostly, fails to charge, eject, I've never shot a magazine wo errors, I literally let new people shoot it so they learn safe clearing practices cause that's what they mostly doing when shooting it 😢 tips or tricks to actually get it to work well?
I bought this set and had a ton of problems in my Ruger AR556, specifically failures to fully eject with the brass getting caught up in the ejection port. I did two things to resolve the issue and now it runs great. 1. Put a little fuzzy side velcro on the top front of each magazine to take up some of the slop, and 2.

The answer to the bolt hold open problem is (AR-catch22) look it up. FLAWLESS!
Are those new magazines with the red follower any different than previous generations?
Primarily in design. Function is the same, but with an added piece on the follower to better actuate one of the old bolt hold open kits.
I just wish they still included them in the brown hard cases.
This doesn't gunk up the barrel? Say you have a really nice, expensive AR-15.. Would you suggest against using this in that expensive rifle?
we wouldn't recommend it for prolonged use without cleaning. even just switching back to 5.56 on occasion will help that from building up
I wish you would have given the price definitely sounded like an infomercial
I bought this and use it quite a bit. Just be aware this will not be as accurate as a standard 22LR because the 556 rifling is different.
I had issues with mine out of the box and CMMG was great about getting it working for me. I bought the forward assist piece too because occasionally a round wont feed all the way (especially when the chamber gets a little dirty). Some ammo feeds and works better than others.
I keep seeing different answers to this question: What grain and type of ammo have you used and what tends to work best? Id love to keep the price under .08 cents a round with todays prices but i just keep seeing conflicting answers. i have a 16" Stainless Steel Barrel PSA built rifle.
The main thing is to go for copper jacketed ammo. It just feeds better. We see a lot of 36-40gr running great.
I have 3 of these and currently buy additional mags for them.
Btw, is this legal against the California AWB? Other than the 10 round mag version?
Is that legal in Canada?
Can you guys make a conversation kit for 308 to shoot 556 like the colt 901 did
my bolt doesnt like to seat all the way with hollowpoints. is this normal for your conversion kit?
Does anyone know what ammos go good throuh this. Just bought mine and remington golden bullets are jamming alot. Trying cci and winchester next
I don't have to convert my barrel? Will the round wobble down the barrel if I don't have the correct bore (the bore being bigger due to it being spec for .556/.223)?
I have a stock Sig Sauer M400
It's minimal difference in bore. The biggest differential will be the twist rate. The conversions aren't going to be for accuracy, more for cost effective training.
@@CMMGLink to conversion kit?
I have used the right hand kits with no or few problems. I am a gunsmith and have owned my own shop for a very long time. I am a left hand shooter and just received my new left hand kit. IT WILL NOT RUN IN ANY OF MY GUNS !!! I have tried it in FIVE different guns ranging from 10.5 inch to 16 inch barrels none with 556 wyle barrels. I have also tried using the Buddy Kits with no help. Wondering if I just got a lemon ? Not trying to be an ass but Something just ain't right? Help please?
Please email our customer service team. They'll be able to go into this more in depth with you.
I own and have used your conversion kit in the past with good results in general. I stopped after picking up a 15-22. Been looking at your dedicated 22lr uppers which I assume work just like conversion kit without the chamber adapter. Couple questions, since I have a bunch of 15-22 magazines I was wondering if you have tried the Better-Mag adapter in your conversion kits and 22lr upper? Also, with the dedicated 22lr upper what kind of accuracy can you expect with something like CCI MINI MAGs? I ask because with the conversion kit I have noticed I get some back and forth movement inside my upper which seems to open my shots groups up somewhat.
We've not tested with the Better-Mag adapter, but know a lot of people run them with little to no problem. Regarding the dedicated upper, the main thing is you will have the correct twist rate therefor a more stabilized projectile and it will be more accurate. While the conversion kit is decently accurate, dedicated is the way to go if you are wanting the best accuracy.
i use that mag adapter, it's awesome. last round bolt hold open, easier to load mags, never have issues. it's on my 4.5" cmmg 22lr upper and after 5k rounds i still can shoot out a bullseye
@@CMMGhey there. I just purchased one of the conversion kits. For some reason and Ive tried it in two different rifles. You either have to hold pressure up on the mag or bench rest it or it will not feed when pulling the charging handle or feed while firing.
@@tlc239 what kind of lower? That sounds excessively loose
@@CMMG I tried it in a Ruger 556 and a PSA lower. The mags are tight no play thats what makes no sense. My buddy has a conversion kit feels the same as mine but his works great. It runs great when I bench rest but I cannot chamber a round unless a lil upward force on mags.
The S&W mags hold open when combined with catch22 gen2 😢 Too bad i have to mix venders because lack of forethought in cmmg mag design.
Wouldn't say lack of forethought. Our .22lr magazine interface has been out since before the M&P15-22.
Why can you make a mag that fits tight in the mag well. I only buy Black Dog because of this
It honestly depends on the magazine well. With so many options, there are a lot of lowers that are different specs. Our original mags had a provision to trim a place to make them work better in your gun. However many people didn't know how to do this, so we had to make to a smaller spec to fit a wider range of lowers.
Turn your semi auto ar into a bolt action .22 that has no charging handle so you use your keys from your pocket to charge the bolt after every single round that fails to feed every single shot. Spend more time unjamming your rifle than ever before. Super fun times
I tried two different rifles that function perfectly, tried 3 different magazine types and 4 different brands of ammo. Still failures to pickup next round/ double feed issues almost every single shot.
If you use the magazine as a foregrip and push it up and slightly back you can get the bolt to pick up the next round but it's comically just barely snagging them to where if you don't push up on the mag while firing it will miss the next round completely and you end up with an empty chamber and a sad click when you pull the trigger. Then it's time to cradle your AR like a baby and push in on the mag while using your keys to charge the bolt again in hopes of chambering one this time. Just buy a Ruger 10/22 for 100$ more than this piece.
It uses the standard AR-15 charging handle idk what you're on about
Have you contacted our customer service team? This is far from the normal experience people typically have.
do you offer it in 22wmr?
Do you need to shoot a certain grain such as 40 gr?
Might be a dumb question, could you use this conversion with a 300 blackout barrel setup, I know it’ll probably be less accurate for sure but besides the case shape I don’t know if it would work or not
you cannot. the chamber adapter is for .223/5.56 chambers only
My favorite tv show! 😊
Where can i find the mags alone?
part number 22AFC2B on our website or your parts dealer
What year did you guys release the 10 round conversion kit? Its awesome!
It's been out for quite some time. We'd have to look for the exact release, but with magazine restrictions, we had to adapt early. We'd estimate every bit of 8 years.
Are the 10/25 mags convertible if legal?
You make a speed loader to go with those mags?
We don't make it, but we highly suggest the McFadden Lightnin' Loader. We have them on our website. Makes events we go to so much more manageable.
FYI the 22lr conversion kit does not work in the dissent platform.
Sorry. Just traditional ARs for now.
@@CMMG Yes sir, I called at the dissents release and was informed. I can't wait till the engineers get it resolved. Love y'all's company keep up the great work.
Will this work with a piston ar? An Adams Arms piston to be specific?
It should. We modified them many years ago to work with most pistons. Looking at the Adams Arms, they're similar to our old ones and should be good.
Can I run these with my surefire RC2?
Will it work in 223 wyle or does this count as standard 223
Yes it should work. The .223 wylde is different bc there’s a part in the chamber that bridges the gap between .223/5.56. They’re all .22 caliber cartridges tho
❤❤❤❤❤❤
So the bullet is fired through a 223 barrel correct?
correct. this conversion adapts the chamber to accept the .22LR cartridge, and allows the magazine to feed properly
Is this kit compatible with PWS rifles with long stroke gas piston system? Specially PWS MK111 Pro?
The .22 conversion is straight blowback, so there's no need to worry about the operation. As long as the piston is removed from the system it should work just fine.
