⁠@@geraispadilla213honestly the only purpose I see for full auto is for fun at a range. I’ll hit more of my intended targets with semi auto than wasting ammunition with auto. Even if it has auto functionality I’d stick to semi in an emergency.

[@PYRO-ON]

@@elliotalderson2479 I agree…. If you want to go nuts at the range, you can always bump fire a semi automatic rifle anyway or if you want a little bit more control, you can always get yourself a binary trigger since bump stalks and now even rubber pistol braces intended for disabled vets for better control have been made illegal by our ATF tzar … it’s funny how the US government can leave billions of dollars of fully automatic weapons to the Taliban but take away every gun right for us responsible law abiding citizen gun owners… what’s good for the goose is good for the gander they should make law enforcement, the FBI, the ATF, the CIA all stick to the same gun laws but no they have to have full auto everything… what an absurdity. #REPEAL THE NFA DEFUND AND DISMANTLE THE ATF ….

[@cowsauce9099]

After watching TONS of forgotten weapons and really understanding various styles of BCG/FCM, the modern AR has a truly amazing design. The direct impingement system keeps the overall weight of the rifle low and the design of the auto sear and bolt carrier create an extremely simple out of battery safety. For a rifle which people talk so much smack about, it really is a beautiful piece of engineering. Awesome video, I have been curious how this functioned for ages.

[@ronmcever405]

A Mr. Stoner designed One so slick, it wasn't shipped with cleaning kits. I"m still pissed about. That. A lot of good, decent men died after firing. 3 or 4rnds and it didn't go bang anymore.. Fortunately, someone solved that problem. The AK was another dependable weapon. 99% of the time if it had a round in the chamber, it would go bang.

[@siswantoafu6277]

[@muddyhotdog4103]

@@ronmcever405 The main issues was that of using old stock ball powder instead of the IMR which raised the dwell timing, and not chrome lining the barrels in a humid a$$ jungle environment creating pitted chambers etc (huge problem with the 556 straight walled cases especially when you raise the port pressures).. No cleaning kits/not cleaning just exacerbated the problem ten fold on top of those major issues. But ya after the A1 upgraded modifications along with cleaning kits it worked seemingly fine, but it was definitely rushed into service as a main fighting rifle. The ak47 went through many problems in the beginning too (ie type 1 to type 2 ak47s) but it wasn't rushed into a war before major testing. Its design was almost already 20 years old by the time it saw action in Vietnam and had any issues worked out long ago by then. There were so many problems plaguing the m16 before the A1 that it was border line criminal that soldiers got that rifle. It's not a problem with its design though, it's a great rifle and still to this day.

I would be interested in seeing a set-up for 3 round burst. But very nice informative video on exactly how it works. Great job.

[@stickpge]

old comment but still, in practice the 3 round burst works the same as combination of a semi and full auto system, the first three shots are basically fired in full auto but with a system similar to a ratchet each cycle basically engages a small teeth part attached to the firing mechanism of the rifle which can only go one way, each time the gun cycles the next tooth of the process is engaged once its done that basic rotation 3 time the system basically trips like a semi-auto rifle and the mechanism needs to be reset by letting go of the trigger afterwhich the whole process begins again

Also, D-Day would have been nearly impossible without America's involvement. We pushed up through Africa into Italy (Successfully defeating another axis power) and also took back France.

In Firearms Instructor School, we never called it a primary sear, the T.O. called it a "Trigger nose" and a "Hammer Notch" NOT a primary sear. The only sear mentioned in the curriculum and T.O.'s was the sear, that you referred in the video as the "second sear" 3 round burst. A second disconnect, different safety, a 3rd burst cam added. You can use the same safety in the 3 round burst as in the full auto.

[@chuckvan1568]

Hope Is Key There's a lot of information out there regarding this which you can find with a google inquiry. It's important to note that FOPA 1986 was intended to provide relief from some of the regulations that infringe gun owners rights."In 1986, to reaffirm Congress's intent in passing the GCA and prevent improper law enforcement by BATF, Congress approved the Firearms Owners' Protection Act (FOPA). Near the end of debate on the measure, late at night with most members of the House of Representatives absent, Rep. William Hughes (D-N.J.) introduced an amendment related to fully-automatic firearms. Despite an apparent defeat of the amendment by voice vote, Rep. Charles Rangel (D-N.Y.), at the time presiding over the proceedings, declared the amendment approved. Hughes and Rangel were longtime "gun control" supporters."The important thing to note here, is the part about the reprehensible Charles Rangel who made a declaration that was contrary to the voice vote and got the amendment inserted into the bill when it shouldn't have been. He also refused to allow an actual vote on the amendment. Democrats Rep. Rangel and Rep. Hughes were long time gun control advocates working in concert on the same committee. "BATF interpreted the amendment as a prohibition on the civilian possession of any fully-automatic firearm manufactured after May 19, 1986. The effect of the interpretation has been to "freeze" the number of privately owned fully-automatic firearms at roughly 150,000, an exact figure being unavailable due to privacy protection requirements that apply to tax-based laws such as the National Firearms Act. The crime-fighting utility of the 1986 "freeze" was questionable, since no legal, civilian-owned fully-automatic firearm had been used to commit a violent crime. BATF's director at the time, Stephen Higgins, had testified before Congress in 1986 that the misuse of legally-owned fully-automatic firearms was "so minimal as not to be considered a law enforcement problem." From www.nraila.org/articles/19990729/fully-automatic-firearms

Thank you for this very well thought out detailed explanation.

That being said I was always curious as to how full auto worked in the M16 which was the rifle I had with no forward bolt assist and a three prong flash hider.

Awesome demonstration! I've watched animations that explain this, but your video adds the dimension to the operation! Thanks for sharing!

[@Donman5]

Best visual representation and explanation of full auto I've ever seen. Thanks for this!

[@johnnyem-grafix4024]

This is by far the best , most informative video I’ve ever seen yet on you tube on the ol’ semi… - auto - science : breakdown and you cover every nook and cranny ! This is awesome

[@pgoff0000]

Modernpawn. This was one of the most educational videos i have watched on how an Auto works. I had no idea. Can you build another video explaining how a bump stock is different than full auto? Your explanations are very well documented. Thanks for a great explanation and clear video.

[@incognitobail5888]

Very nice explanation. Concise, to the point, and explained like a watchmaker explained an engineering to a layperson. You should do more 'How things work' video.

[@MSRLR]

Very well made video. Very easy to follow, explained very well. Great job!

[@bryanduchane2371]

One of the few channels with less than 40k subs to have a video that gets 2+ million views. Got this made you a bunch of money..... Great video!!

[@homefront3162]

I love gadgets and machinery, I wish I could play with or build these.. The ingenuity is awesome

[@hoosiered471]

Great video!!! Very clear and concise. How in the heck did Eugene Stoner come up with this design and all the intricate machining. Crazy man!

[@victorglaviano]

He was an aircraft engineer!

[@geraldwest3428]

Excellent and very interesting. Thanks for your time in sharing a comprehensive explanation and description.

[@atab555]

I love it. What are the differences with 3 round burst?

[@modernpawn]

Hard to explain in words, but its like a three hook disconnector plus a second sear, a bit more complex. I will try and get my hands on one and do a video

[@Baconatorz]

you took the words right out of my mouth

[@jbmiller717]

modernpawn please do i am also interested in the mechanics of that one. its not as if i can afford one at the moment but i am a mechanical engineering student and always like to know how this stuff works. The full auto is insanely simple but burst fire defiantly seems more complicated and interesting. (and useful) thanks for the great videos!

[@2111onyx]

three round burst has a timing wheel thats like a notched sprocket on the side of the hammer. when the trigger is pulled in burst selection the shallow notches let the hammer cycle until the third notch which is deeper catches the sear stopping the cycle of operations. until you pull the trigger again. hope that helps explain it.

[@toohyphy4068]

Brandon Miller burst works the same way with both sears. But has a different trigger (has a semi and burst disconnecter) and different hammer(has a burst cam on the right side) the burst cam has two deep notches in between the notches required for three rounds to be fired. Once the deep notch is hit it will reconnect the hammer sear and interrupt firing until the trigger is pulled again. Burst was designed well. But the burst cam affects the semi auto trigger pull depending on the notch the disconnector is in. I am a 91F. I repair all the weapons the US Army uses. From a 9mm M9 to a 155MM M777A2.

[@SCHW3DER]

This is EXACTLY what I was looking for, thank you.

[@raiunjoulfberht2108]

Hands down, this is the Best full auto/semi auto function explanation video out there. Thank you for the time and effort you put into this Knowledge Transfer, this is important stuff.

[@6857100]

Interesting. I had a friend in the national guard who after coming back from annual maneuvers was told that the unit was in big trouble because somebody had swapped out parts in the lower of one of the M4's. Gee, I wonder which parts they took?

[@user-do1fq8oy9c]

The parts are available over the counter from many sources. The masters want a monopoly on violence. They won't stop till they have it.

[@Defender-Guy]

Great video. So how does the 3-shot burst work? I always thought that would be more useful than full auto!

[@KLEEN454]

thanks for the detailed explanation!

[@jimmycolby8823]

Very informative 👍🏻 I'm not a very mechanical guy thank you. Doesn't take much to become full auto !

[@AmmoGunsAndFun]

Cool video nicely done on showing the difference of semiautomatic & fullauto

[@jackpalek2978]

Very good video, always wondered what the difference really was. Thanks very informative and well done.

[@velocity550]

Great information. Always wondered how that worked.

[@hmack1234]

The absolute BEST explanation of how the full auto mode works! Thanks for taking the time, man!

[@dam00k]

The most concise explanation I’ve seen. Thanks.

[@billcollins7009]

Best video I've seen explaining the functioning! Thanks for posting this! I second Alexander's request for a 3 round burst explanation. You have a natural talent for teaching and having you explain it in the same fashion as this video would be great.

[@SteveHMcIntosh]

that is a damn informative video. well done!

[@oldbenkenobi2864]

I'm glad you explained this. I'm still new to this but I was thinking that if you like to live dangerously you could trim your disconnect and it would do the same thing. But as you explained the BCG is designed to stop someone jackass from being dangerous and doing just that. Also I guess the hammer wouldn't have the momentum as its now following the bolt.

[@1800pouned]

You can buy m16 bolt carriers online. You can also make up for the cut out metal by bending, welding and sanding the missing metal on.

[@556online]

Super informative video. Everyone has to start from somewhere to learn this kind of stuff and this was like a text book illustration. Great job teaching.

[@Make-Asylums-Great-Again]

Thank you , I just converted 3 of mine to FA. 👍 SAVED ME A TON OF MONEY

[@WingsnBones]

Excellent video. Very clear explanation.

[@big_nasty533]

Great video. Thorough and precise. One of the best educational videos I've seen.

[@PhantomEagle..]

I got a bad feeling that were all on a FBI list after watching this

[@irgski]

fascinating mechanics as well as mechanical timing!

[@richrich685]

Best explanation I’ve seen so far! Thank You!

[@thefancytiefling]

I'm sorry but in the beginning of the video it looks like you had a regular m4 carbine that you smashed the barrel into a wall and squished it into a smaller rifle
