- In this video I talk about the mechanisms in firearms that allow them to operate in different firing modes, for example semi-auto and full-auto.
This is the site I downloaded World of Guns: store.steampowered.com/app/262...

If you are wondering what program I use for the creation of this video, please check the description. It should be included on every video in this series, if not let me know.
dont worry i know,its guns disambelly world

CAN ANYONEPLEASEHELP!?!?! Ok so with a ar-15 p80 in 556 and when the trigger goes forward it doesn't release from the first catch(hook) so the hammer is unabletobe released by pullingthetrigger... so its not together yet but the trigger assembly is in and when the hammer is pushed down it hooks but you either have to push the trigger forward a very small amount and it releases and resets allowing the hammer to drop when the trigger is pulled... it also works if the selector switch is moved from fire to right around half way to safe. At that point it releases resetting then you put the selector back on fire and it is able to fire...it only has to go half way not all the way to safe. this happens every time... so should be working correct? Or does the upper have to be on for it to work properly? Some people said they had this problem because of a small burr on the hook so it wouldn't reset until they sanded it down smooth. don't think that is the problem because it's already been sanded it down... does ANYONE HAVE ANY IDEAS ON HOW TO FIX THIS AT ALL? PLEASE LET ME KNOW... Thought about getting a drop in style trigger but they're a little expensive right now. Not understanding why what is already here won't work... EVERYTHING was picked up at the same time from the same person and there was no shortage of people getting the same thing and MANY were coming back after a prior purchase not just first time buyers! Asking around everyone had nothing but good things to say about their prior purchases/builds. Please if anyone can help it would be HIGHLY APPRECIATED!!!
Just an FYI on terminology:
1) That "hook" that holds the hammer back on semi-auto mode is called a disconnect.
2) That piece that holds the hammer back on full-auto mode is called an auto sear
Though I appreciate the effort, it drives me nuts when there’s a misrepresentation of what the parts are called and their functions. I’m not much of an AK guy but I understand the AK trigger (Semi and Auto).
I'm not sure why the disconnect needs to pivot independently of the trigger and sear.
@@smorrow If the disconnect's rotation was locked to the trigger's rotation, it wouldn't be able to catch the hammer to allow semi auto firing. And the auto sear rotates independently to restrict the hammer from falling until the bolt is fully in lockup, to prevent hammer follows or out of battery detonations.
Thank you. I was just about to mention that
Probably best video explaining clearly how trigger groups work
this was such a great video! from someone who had no idea how firearms work (apart from pull the bang switch to make a hole in the target!) I can actually wrap my head around how it all works!
Thats pretty cool that you actually used a very rare (in the M16 / M4 platform) 4 way trigger group with Safe, Semi, Auto and Burst. Actually this is the Colt design with Auto being the first selection off of safe in the position Semi usually is. Safe 9 o'clock, Auto 12 o'clock, Semi 3 o'clock, Burst 6 o'clock.
The DPMS aftermarket version kept semi and auto in the normal places.
You can buy safe, semi, auto and safe, semi, burst trigger kits for under $150 but these 4 way kits are usually $500 plus from being so rare. Too bad the 4 way kits suck in real world use because it makes the trigger pull in auto super heavy since you're pulling against both disconnectors being depressed. This is why they arent popular and hence rare.
Toki -EJ1 I didn't know that. I always thought there was only two different set ups. Semi and Auto and Semi and Burst.
great video, watching the ak part allowed me to better understand how the M16 trigger group works when I looked at it in game before watching you explain it
Very cool program, love these operation and assembly/disassembly videos.
By far the best video on this that I’ve watched!
I’ve always been curious about out the burst fire mechanics played out. That was awesome thank you man.
This is why gun engineers made their big bucks! an awesome work of mechanism and springs.
I love your mind. Not to be creepy, but the way you built that, I could take classes from you and love every second.
It's actually a "game" on steam
@@skinnygunsmith7565 it doesnt distract from how he made it all come together. Just displaying the game wouldnt have served as much of a purpose

Wow that burst fire is genius dude. Imagine being the genius that invented that masterpiece. And thank you! If only school had been stuff like this. Very interesting!
And we used to call druggies stoners! The Eugene Stoner had some creds.
That’s exactly what I was thinking!

@The other Archer thats complete bs
The rifles look similar externally but have absolutely nothing in common by function
@The other Archer Different to you yeah...
I actually did.
@The other Archer what you are talking about is a very common myth in the gun world similar to
A 50cal flying close by will kill you
The ak/doesnt jam has a higher mud resistance than the m16
All these are common gun myths
Very interesting how many parts are actually working in unison.
Great video man.. Very informative
Fascinating. Thank you!
!! Awesome video I learned alot!!!
Great job at explaining it!!
I always wondered about the function of select fire firearms. Thank you for the Great explanation.
Great information video
Fantastic video
This was cool to see like this thank you
Good video. Very clear and descriptive.
I didn’t expect to understand this so well
Good job man love u from India Punjab Amritsar
That is badass thank you so much!
The part in the AK that your calling a Sear is the hammer, What you refer to as the 'Hook' is the Disconnetor/Sear
Great Content Great educational info: I've worked with AR's so long, the AK fire controls looked so foreign to me..
I like the program that illustrates how a gun functions. I’m looking forward to being a gunsmith this would be perfect for me.
Great video
Could you show us how the coat hanger machine gun works???
You made a super nice video. Please don’t take this as an insult, but the sear is the long straight piece shown just behind the shells. The disconnector is the small hook on top of the trigger.
Thanks, your video is very helpful, i can have good sleep now :)
Good stuff thanks
The trigger mechanism(s) on guns have a lot in common with an analog clocks mechanically speaking (i.e. escapements, and the gears/springs that time the complications).
Exactly. Nowhere is there a part in any gun called 'intent' to make it sentient, subject to criminal sanctions.
Great video!
Any chance for a Tavor SAR trigger video like this?
Better than any hollywierd movie.
Thanks.
Useful 👍🏻
Being into firearms and owning an Ak,Ar multiple of them actually. This video really shows how easy it would be to convert from semi to auto.but anyone reading this don’t do that follow the rules and keep your freedom
Still a great video!
what happens if you would try to change the fire mode while the gun is firing?
Nice model, what software?
Cool 😎 stuff
Just imagine if an engineer had designed a similar system back during the civil war era rather than the hand cranked multi barreled gatling gun. Ironically the gatling used a very complex arrangement of cams, gears, bolts, and components to make it all function in unison. You would think that designers back in those days would have grasped the concept of a single barreled locking bolt mechanism that employed an auto sear. If a country had done so back during those times and could have mass produced it - they would have undoubtedly owned the entire planet as no other military would have had any chance against such a weapon
In the mid 1800s they did not have the ability to make parts to the tolerances required by modern firearms,that's why the Gatling had a multi-barrell design,based on a seed drill, and would jam if cranked too fast.
making a single barrel repeating firearm with black powder as a propellant is not feasible, the barrel would foul too fast. one of the reasons gatlings can work is that they split the fouling between several barrels.
a gatlin gun uses multipule barrels so they don't get hot as fast as a single barrel.
It's very easy to design something complex. It's very difficult to design something simple that works well.
Weapon engineers are geniuses!
So what componets can i buy or print to make this happen or can i jus do this w some filing myself??
all we need now is, someone to do a animated comparison, with an full auto m4 fire control, compared to an ar-15 forced reset fire control.. now that would be a cool animation especially if it could be done side by side
why? the speed of the bolt is what controls either one.
But how can the semi auto ones work withouth the autosear/lever holding back the hammer while the bolt is not closed? Does this mean i could release the hammer while the bolt is closing causing a malfunction/jamming?
No, in semi-auto mode, the disconnect catches the hammer, preventing the hammer from going forward until you reset the trigger and then pull the trigger again
thank you
Great video! I have a question, Does the burst ratchet always reset even if only 1 or 2 rounds we're fired?, and what ensures 3 rounds will fire? (say you only tap the trigger, will only one or two rounds fire, then the next burst only be 1 or 2? or does the spring always reset the ratchet wheel? it seems to me from the animation the only thing keeping the burst going is trigger pull and also the ratchet wheel is always trying to reset against the the hook.(meaning it will always fire 3 rounds as long as you hold down the trigger????). Please Help Me clear this up, thanks again!
From what I've gathered from people who have used the gun, it does not reset, and that was one of the reasons the burst mode was dropped in favour of semi-auto and full-auto
WoOsKii 1 if you fire 1 shot in burst mode and pull the trigger again two more will go off. Fire 2 and next trigger pull one will go off.
@@pukalo And burst has reappeared in the M-4 because Privates use too many boolits in auto. At least my E-7 friend told me they were using burst when he was in the sandbox during the 20teens.
I am actually building a Lego mp5sd (completely functioning firing hk slap all that) i think I have an idea of what to do now thank you very much
so basically if i do a bit of magic with the fire selector on my semi auto Saiga AK 103, i can turn it into full + Semi auto rifle?
So all i need for a ar s a welect fire switch ?? Or can i fab something on my own
If Ak full auto spring is week does this have any negative effects on ak performance
Recoil spring? A weak recoil spring makes the gun cycle slowly and firing more harsh
I love the simplicity of firearms, not simplicity, but you would think there’s more going on then what is actually happening
Maybe you should cover how to add more bass to your voice!!
The ATF keeping a close eye 👀
Is there something that prevents people from modifying an AK from being full auto? Going by this animation, the only thing it would take would be filing down a portion of the safety selector switch so that it only engages the disconnect rather than the trigger. I don't have an AK to look at, but the hammer on my AR-15 is cut short preventing anyone from putting a notch in the back of it for an auto-sear to catch, thereby preventing it from being easily modified to full auto.
It looks like the tail on the disconnect that would normally interact with the selector switch lever is missing on off-the-shelf AK's
Well, you’re missing a lot. Normal rifles, don’t have the 3rd pin holes required.
You can’t just file a safety notch, because the main pieces for FA are not even installed in most rifles.
You can’t just add a full auto hammer with the notch to your rifle and it’s suddenly working.
All of these parts, require a 3rd hole to be drilled in the receiver and the parts added.
You can buy the parts online easy to convert, but if you drill the 3rd hole in your receiver without proper paperwork, tax stamp, 07/02 FFL or an SOT permit, it’s a felony.
But creating a full auto by just filing something down is a myth.
The actual mechanical pieces are missing to even do it.
Anything else, and you’ll have issues with the bad guys.
The NFA needs to be abolished, but with our Current political climate In the US, we will never elect lawmakers who will be pro gun enough to undo the damage.
It really sucks.
Also, with the psychotic lunatics who’ve been shooting people up, we will never regain our rights to full unhindered 2nd amendment rights.
I’m the type, that I believe if you’re rich and responsible enough, you should be able to get an M1A1 Abrams tank or a fully loaded F15 Strike Eagle fighter jet.
Our founding fathers didn’t put a limit on our second amendment.
I only draw the line at weapons of mass destruction. I believe chemical and germ warfare, as well as nuclear technology should be eliminated worldwide.
Responsible, upstanding American citizens should own everything our military owns
Prison is what prevents most of us in the US from making such mods.

Hello,dear Mouse Gunner.
I am from Bangladesh.I am in need of an animation describing the mechanism of STK AGL Mk II weapon.
10:06 that's the safety right?
What if I shave the hook other than obviously a class a felony would I also get a full auto ak?
No you need to install the auto sear. Otherwise you would just have hammer follows which would essentially render the firearm useless
This is also referred to as "drilling the 3rd pin" and according to the atf whether or not you have installed an auto sear or even own one, the moment that the 3rd pin is drilled on the receiver you are in possession of a machine gun. Highly HIGHLY illegal. 10 years and 250k dollar fine. Not even remotely close to being worth it. Save up 30k for a pre 86 machine gun, get an FLL with a class 3 SOT license. Or move to a 3rd world country with no gun laws.
Why u so smart
what if we remove the bend on the bolt which disengages the lever then can we convert an auto ak47 into a semi auto even if we select it to auto mode ? i'm talking about removing the downward bend part on the bolt which disengages the lever when the bolt is closed at 6:20 . I hope you understand me.
Unfortunately if you remove the "bend" it will prevent the lever from being pulled forward to disengage from the hammer essentially rendering the firearm inoperable and require you to have to replace the bolt. If what I see is correct at 7:08, you would have to file the back of the seer (rear hook) flush with the back of the trigger to make it impossible for the weapon to achieve full auto making it essentially safe/semi/semi instead of safe/auto/semi.
@@MrRangiku01 thank you for making it clear for me. Ak47 is clearly can't be converted to semi auto just by filing off the bolt.
I have another question about m4a1. What if I place a semi auto bolt in a fully automatic m4? Will it not stop the fully auto mode to work? Bcz semi auto bolt will not disengage the auto sear and the hammer will not be released in auto mode. I can have a separate full auto bolt if I want to shoot in auto mode. Otherwise just keep the semi auto bolt in the gun to keep it as a semi auto gun. In my country laws are not that strict and if this thing works I can have two bolts.
@@KK-px4hh it would be less expensive to replace the full auto safety with one that's semi auto only.
when installed, the semi safety will not disengage the disconnector from its primary purpose even when flipped to the auto position. as a result, the auto sear never gets involved in the firing cycle and no wear and tear on receiver's pin hole nor the auto sear assembly.
the pistol grip should be removed to avoid stress damage to the receiver via the safety detent.
@@tomacton6718 If it works then this is the best and cheapest option i guess Bcz an extra m4 bolt will cost a lot.
What if we remove the hook for the semi?
Does it make it into full auto if theres nothing holding the hammer back?
What era ak is this one based on cause that auto sear looks very odd usesly it looks like a banana
But there no battery in such fire arms
"In battery" in guns means "breech is locked"
Can you do a video about full auto Glocks?

No
What game is this is it on mobile
World of guns i think.
Amazing how stuff works minus that program lol. There's a lot going on with burst fire. Fuckin brilliant!!
Could just swift link and bam. Too bad gov infrindged on us in 86
Wow I am technically inclined
Can you convert a semi auto to fully auto? Ak-47
legally? yes if you get a manufacturers liscense you can do anything you want but you can't sell it to anyone excet leos and govt agencys. I am not sure but I think you have to destroy the ones you made for yourself if you quit renewing your liscense.
Now explain a binary trigger. Or is that illegal?
I wish game designers would research stuff like this bc cod is getting ridiculously stupid for how it's guns work

in before the atf takes this down
m4 is so complicated
Once Biden sees this video, he will freak out and order the ATF to confiscate this ghost gun.
Please stop the supper high pitch HELLLOOOOO
its a akm
Non ak47, akm is civilian model,, same difference between a M16 and Ar15
Gotta get my girlfriend one
good gawd, man. at least use the proper terms for the pieces involved.
hammer, trigger, safety and... DISCONNECTOR.
calling the disconnector a "hook" sounds juvenile at best.
good computer animation tho.
Got a Romanian parts build ak, they filed down my selector so it can’t hold down the disconnector. Damn commies
