@@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.
@@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 …. If this was still America, ATF would be the name of the convenience store not an oppressive overfunded federal agency with nothing better to do than make more draconian laws to oppress their own citizens to keep the left happy.
Spent 28 years in the Army, never really knew how that worked. Funny how my priorities were weapon cleaning, weapon employment and weapon proficiency. Excellent video, thanks.
I'm a retired Army E8 - Abn Inf guy from the Vietnam Era. I have seriously abused many M16s with absolutely zero misfires or problems. It was a huge change from the M14 because of its light weight and you could carry much more ammo in the field.
@@BohappenstanceClick, Soldiers do not like changes to weapons or weapon systems. We were well trained on a rifle, machinegun, or other weapon and knew it inside and out. Then, along comes a replacement. Examples; M1 rifle replaces by M14 that was replaced by the M16. The learning curve starts all over again.
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.
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.
@@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.
@ronmcever405 hey brilliant, Mr stoner had nothing to do with the decisions the bean counters made. Seems like you don't know much more than what your crazy stolen Valor uncle told you.
Hi! This is Herman:-) I m from San Antonio Tx. I had alot of learning and studying about Trigger "Full Auto Fast" and Bolt Carrier. Thank you for Good Job:-)
This was incredibly educational, it's rare that anybody on RU-vid has the guts to show how a full auto firearm works. I watched a guy who was working on some police departments rifles and he would show the part where the auto sear was.
I spent 17 years in the US Army Infantry and retired in 2008. I never knew this!!! I actually own 3 AR's now! Damn I wish I knew what parts to squirrel away back then!!! Lol
i served in the R.A.F. Regiment 3rd squadron so i praise your long service..god bless your devotion to your country as i showed mine to and i know very well how tough it is and unfortunately the price you pay in body,mind and soul....good for you sir, takes a hard man to serve 17 years...my utter respect for such service....
dude really? you sound pretty stupid then, what did you do cook? you can buy all the parts legally today, you dont have to steal you worthless phuck. just dont drill that hole in your receiver... wait you dont know what part that is either.. stupid will keep you safe..
I fought in Iraq/Afghanistan and never once used pew, pew switch in full auto in a fire fight on my M-16/M-4. Aimed fire was far more effective as we left the suppressing fire to the M249/M2 gunners. Great explanation of the select fire group function.
Very well explained, I'm 61 and have a somewhat fair knowledge of firearms, however, I never quite understood how full auto worked..... Now I do, I thought it was only the seers that controlled auto, didn't realize it was the bolt as well. Thank you.
@@nicholasstevenson6466 The USSR did the most against the Germans, the only reason they didn't counter attacked France was because they were busy defending the eastern front
@@mrprussian1694 I'm sorry we were over here kicking ass on two fronts (maybe even 3 if you count the Africa campaign) with far less casualties than the Russians. Sure they arrived at Berlin first but constant bombing raids on the German interior from the USA helped the Russians significantly. 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. Our Navy and marines brought the Pacific theater under control and then our nuclear program ended the Pacific front. You can have your own opinion but the truth remains that Americas powerful industry and military leadership were major factors in the turning point in the entire war.
I normally can’t focus on a lesson in my classes for this long. By the end of the video I realized my mouth was dry from being open the entire time 😂. This guy knows how to teach his stuff
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
If I remember correctly,it's a little washer with notches cut in, with the 4th being slightly longer. The longer one holds the sear down. I dont remember which pin it rides on
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. Nice video that explains a lot to the general public and even Military for those that have never fully understood how things worked inside...
Tuan Nguyen It was designed by a man named Eugine Stoner, while the patent was in effect I believe he made a dollar for every rifle sold. He became wealthy from his creation, unlike Mikhail Kalashnikov who received nothing as far as royalties for his invention. The greatest gun designer in history in my opinion is John Browning though. His inventions are still in use more than 100 years later. All three of these men were geniuses though.
This video is absolutely awesome, i am from spain where guns are taboo, i just love guns and how they work, i learnt a lot watching videos like this since some years ago and it is fascinating
I've seen a number of similar videos on RU-vid, but this is probably one of the best explanations that I have seen/heard. Your close up shots were great, and helped me to understand the process. The additional visual, of you using the bolt and lower together, was a great training aid. This maybe kind of an old video (as of mid-2016), but again, it is a really good one!
Message to my assigned ATF/CIA/FBI agent… I’m just looking. I’m not gonna use this knowledge. I just like to see how things work. Think nothing of it. My next firearm purchase is just going to be a bolt action rifle, because I wanna learn how to hunt. Like this comment if we’re cool.
Just get a super safety, FRT, or bumpstock(please don’t go the bumpstock route it’s literally useless) all three are legal and all three don’t, by legal definition, make it a machine gun(full auto).
I have been working on my ARs for a while now. I love to learn as much as possible about a weapon, not just shooting and cleaning. This video was exactly what I wanted to know about the differences between SA and FA. Thanks for making it for us. You have a new subscriber. Keep up the great work!
The beauty of that sear edge at the top of the "auto sear" is that it makes the cyclic rate a bit more manageable. Even then, on a military base far, far away...the first time I fired one on full was a bit of a shock with significant climb.
I've messed around with my Issued M4 a lot, probably more than most of the guys I know, and I never really got the full picture until I watched this video. My weapon is of course burst, which is more complicated, but the concept is the same. Thanks a lot!
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.
I love how it's so simple just basically two or three modifications to a semi automatic and you have a fully automatic weapon, course not legally, but I don't think gangsters and criminals really give a crap about legality
***** Which is why there are so VERY few crimes committed with full auto weapons. Though you may have a different perception if you watch a few hollywood cop movies.
if gangsters and criminals really used fully auto weapons in crimes, have you any idea how much ammo they would have to carry around? even in semi auto they can barely hit anything at all, you think full auto will improve their accuracy?
Accuracy by volume that's their motto, and it's not that hard to convert a weapon from some semi auto to full auto, and it's very easy to reload your own bullets and cheap; I think it's plausible.
***** How old are you? Are you fucking joking? They have money why would they need to know anything? Or hell they could always kidnap a loved one. Or threaten to bring back an ex-wife...offer to remove a current wife, many ways to get what they want. Think it through next time guy...geez
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
I read the article from the link & wanted to "sign the petition" But didn't see anywhere to sign it. Any direction on this is much appreciated. I'm a FIRM believer & supporter of the 2nd amendment & I believe that law abiding citizens should be allowed to purchase/own/possess whatever firearm they want. Unless of course there is a mental issue. Remember folks, the 2nd amendment protects the 1st. It always has & it always will.
Ron Harper Agreed. Where do I sign? Everyone loves the first amendment regarding freedom of speech, especially those bleeding heart liberals, but when it comes to the 2nd amendment, they treat it as antiquated and out of date. Gotta love the hypocrisy. Everyone, well mostly the liberals are brainwashed into doing everything the government tells them to do. It's nothing but modern day slavery.
hell yeah, we need people on holiday in vegas to be able to own fully automatic weapons, not these bump fire stocks - if he'd had full auto he'd have easily been able to put out 2 or 3 times as many bullets into that crowd.
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
Yeah you would need some serious machining equipment to make these parts, and also probably preexisting parts to copy. All in all it would probably be cheaper just to buy a legal machine gun.
learn as much as you can and build your own lowers as much as possible. I learned a lot building my first lower you really learn how the whole system works and any issues that come up are easy to spot/fix. Good luck on your build and if you get frusterated, take a break and come back later but dont give up. Its been 8 months im sure you are probably done already but just in case 👍
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.
BEST VIDEO showing this EVER!! Impressive. This is an operation I have understood and wanted to do a video on, but have not been able to due to lack of a full auto M16... Very well done.
+Blatant Abuse EXACTLY.. its so simple.. If we didn't have tyranny, it would be easy to make those extra parts and do our own ar15 conversions.. but instead we have to buy them for 10,000+..
+Blatant Abuse you don't need to spend thousands of dollars on a fully automatic m4 or m16a1 or something of that sort... if you don't want to "break the law" you can simply purchase the *binary* trigger system which fires a round both when the trigger is pulled _and_ when it is released. you can fire _so_ fast with this *100% LEGAL* modification that you can actually outrun the bolt carrier LOL....
Awesome explanation of the mechanics and function. As someone with unique mechanical and machining knowledge knowing how things that interest me work scratches an itch.
This is the best firearm educational video I think I've ever seen. Excellent explanation, use of visuals, and continued engagement throughout the entire ten minutes. Liked and favorited.
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.
We need to get rid of the NFA of 34 and that damned hughes amendment to the FOPA 86. I want to have a rifle with a giggle switch that doesnt cost me the down payment of my mortgage.
***** how low is your intelligence? Must be very low if you actually think machine guns are effective at killing both in a micro and macro statistical way. And that they're difficult to make meaning banning them means denying access them to people.
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.
What an amazing video! I've always been into Shotguns (sporting clays and such) but just recently started to get into all firearms. First I got into a Revolver kick, and now I'm interested in semi auto pistols and rifles. I couldn't for the life of me think inside of my head what the mechanical differences were between semi auto and full auto... and this video was probably the best explanation on the subject. Thanks!!!!
Awesome video! Didn't realise there was that much involved! Knew somewhat of the components of the selector switch, but had no idea that the bolt had an effect on the overall firing!
What I find even more impressive is the ingenious/wizard magic of how the 3 round burst works. I spent a lot of time taking apart and putting together the M16-A2 rifle and I still couldn't figure out where they put the magic fairy dust in that trigger to make it fire 3 rounds in under 2 seconds.
Thank you for this very well thought out detailed explanation. Although having used automatic weapons during my service in peace time and in combat my experience with the M16 in Vietnam changed my thinking that full auto is really useful. Aimed fire does more to bring down the enemy than spraying bullets using full auto. 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. We were told that the only difference was the addition of the full auto sear between a semi auto and full auto M16. Now I know a little more about it thanks to your excellent video.
wow....very respectful and your service should be praised in a terrible time...i served but i am British but seen and done a great deal of dirty work so my respect sir...some times us vets see and do terrible things to serve our countries and the price can be very high, i know only to well what ''being in the shit'' truly means....my respect sir.....
