Here in the UK, the question of how various guns work doesn't really factor particularly highly in the average persons mind, but when some random question like "How the hell do those guns I just saw in [Title of some random film] count off a 3 round burst?", it's nice to know that someone on TH-cam's usually already made an easy to follow video explaining it for us. So thanks for taking the time and effort involved to make/upload this mate. It may be entirely unnecessary knowledge for me, but I learnt long ago that information doesn't have to be useful to you personally to still be interesting. :D
If you give the trigger a short quick squeeze that only sends out two shots. the next time you pull the trigger it will only fire one shot before disconnecting. Or if you fire a single shot while in burst mode, the next time you pull the trigger it'll fire two shots. And the burst cam also counts when you are in semi auto, so the first time you switch to the burst mode it is more or less random if the gun will fire one, two, or three shots in it's first burst. And to make matters even better, the trigger weight varies depending on the position of the burst cam. so every third trigger pull is lighter than the other two, even in semi auto.
Quincy Owyang It was introduced in the 1980s as a way to prevent the M16A2 from being made a semi auto only infantry rifle. Eugene Stoner also didn't design it.
@@StealthTheUnknown How do you make guns in Algodoo? Before you tell me to download the thing in the description, I just want to say that I mean to make my own guns.
@@spotat6234 also, that’s not something someone can answer well in a comment. Lots of things made with algodoo in general are the result of hours of tweaking and work - some even took days or over a month!
I'm 29 years old and have wondered how 3 round burst works for at least the last 11 years and in the past 8 minutes you answered that and many more. Thanks for a great video.
Ladies and gents, the sig version has been figured out as well. Holy shit, I feel like the Swiss overengineer more so than us Germans! I'll have the video up eventually. Working 8 days a week lately, but I'll get it done :)
Stealth The Unknown The Swiss are basically Germans that have no concern for being economical about their designs. Take weapons for instance; the Germans have a history of fighting wars and they needed to take that into account with their designs. The Swiss simply have the freedom and wealth to go all out.
I used the M16A2, with 3-round burst, in the US Army from 94-97. I could see the cog down in the receiver, but never knew how it all worked. Thank you!
It's like when the Swiss were asked "what will you do when the Gemans come that are twice the size of your army"? They replied. "We will shoot twice and go home"
He must of been Air Force because they don’t teach you how to fully dissemble a M-16 or even how to fully clean and run function checks on an M-16/M4. I am army but my brother younger brother and my dad are Air Force and I had to teach both of them how to break your weapon down properly and how to clean it and run a functions check. They don’t even do bayonet, AT4, Claymore, and live grenade training in their basic training LOL oh yah also they don’t teach how to operate the M203 and many other things. I mean their basic training is only six weeks that’s why I always give them a hard time and call them chair force
DMax M249 No, us POG mos in the army only conduct operator-level maintenance on M16. We don't touch the trigger group or we go see NCO and sign some papers and maybe get paid a little less next month.
@@dh7164 I never knew how it worked until army bct we cleaned our weapons so much and me being a gun nut I got to know how it worked lol got our m4s day 3 of basic and I had it figured out by day 4
This video is without a doubt the best step-by-step description of exactly how we are your trigger function in semi three round burst and full auto! Thank you sir for dumbing it down for me.
Tuan Nguyen It depends on what you define as a "genius". If by genius you mean "mechanically clever and resourceful," then yes. But it takes a true mad scientist to design pretty much anything H&K puts out. ;)

Colt had another patent for a burst fire trigger group for the M16A1 - US4004496A from 1977. It's more complicated and I don't think it was adopted for use. I haven't ever seen one, but there may be some old timers out there that have. I'm very familiar with the burst fire group discussed in this video. Genius design, to be sure. Great explanation!

I had a malfunction once where my M4 was placed on semi. It fired when I pulled the trigger and then fired again when I released. Your video helped me understand what happened. The metal on the front part of the trigger, the sear, probably wore down. Disconnector caught the hammer, but upon release of the trigger, wasn't caught by the sear and the hammer sprung forward and wasn't caught. Thanks.
never in my 5 years or so of being an absolute full time firearm enthusiast have i seen this explained so clearly. i always could understand the mechanics of a full-auto AR rdias, but have never seen a working model of the burst "cam?" in action like that. thanks for vid, learned a ton. subscribed
xxskizzumxx Please do! And thanks for the support! This questing has been bugging me for YEARS, so I went to some of the most remote and hidden places on the net, even sites that were NOT in German or English (my two primary languages) to demonstrate the mechanics. With those many months of being a cybernaut on a quest to find the answers, I finally did, and put this together to demonstrate it.
I'd just like to point something out where you were slightly off, you said that if the hammer fired off too early, it could result in catastrophic malfunction, which is wrong, it will simply ride the bolt forward and not fire, because it doesn't strike the fireing pin with enough force, which is easily demonstrated by tying down your seer, or bumpfiring to fast, it is an action known as outrunning the gun.
+Bradley Homer this is true, but I was trying to make the point that it is dangerous and unreliable to have the hammer follow the bolt forward. Though it is rare that this causes any kind of out-of-battery firing, it HAS happened when "outrunning the gun." The results have always been undesirable in those circumstances
+Jason Cox this is so wrong, but I'll elaborate further since you are sort-of on the right track. It won't fire after the first shot if you remove the disconnector, as the hammer will ride the BCG forward (bolt carrier group.) However, some people have allegedly filed the interface on their disconnectors to temporarily catch the hammer, but cause it to slip soon after, effectively turning the mechanism into a rate reducer. This mod is highly illegal, though, and I'd advise against it.
+Jason Cox fair enough. I'd imagine if the firing pin wasn't shrouded, the issue could occur. I'd venture the disconnector had bad engagement rather than being missing.
Finally this explains why everytime I had to shoot 3round sometimes I'd get 2 or 1 shots during a burst. I let the trigger go too early sometimes. I always wondered exactly why my issued m4 did this.
Great explanation, thank you for showing the basic mechanics and not rambling on about other things in the video. Concise and to the point. I'd like this twice if I could.
Yes, thank you! I did my best to avoid tangents and things of the sort, as they always agitate me when watching tutorials or educational videos. Thanks for watching!
Mark Scoble It has been a challenge to find the information on the Stoner Burst Kit. I have had very little luck on the HK or Sig variants, but I have tried. maybe some day I'll get some ffl and own a few, or the U.S. Govt. will become a bit more compliant to the constitution. Who knows?
***** If you are interested,I have an HK book that describes the burst mechanism of MP5 in detail.The book has 28 pages and it has pictures.This animation was very good and I would love to see the burst mechanism of MP5 in a video like this.I can send you the book, if you give me your email. I also have a question.I already knew how the Stoner burst mechanism works, but I was never able to wrap my head around how the movement of the hammer rotates the cam backwards.You said that it is some kind of ratched mechanism.Actually there is a spring between the hammer and the cam, but I cannot understand how this spring rotates the cam backwards.If you know how this works,I would be thankful if you can help me to understand it.
Catching Fire from what I've seen, there are actually little indexes on the inside of the cam that the spring engages on when the hammer is pushed backwards, but the spring slips over them when the hammer drops. it's essentially a ratchet mechanism with two moving parts: the hammer and spring, and the cam wheel. I'd LOVE to see that book! Thanks for offering to show me :) find me at stealththeunknown@yahoo.com
***** Thank you,it's more clear now.I didn't know how the spring engages with the hammer and the cam.Still if you know of a book,site or some pictures that depicts this,please send me a link. I have send you the book on your email.It would be great if you can make an animation of the HK burst action,since the HK system is more complicated and more difficult for people to visualize.
If anyone is curious, burst was initially introduced to let the shooter fire multiple rounds while not having to worry about when to let off the trigger. Which decreases mental effort and increases endurance in long firefights.
When the M16 was first issued to troops in the field (Viet Nam), they would sometimes 'panic' and fire full auto as the 'norm'! Because the rifle is so light weight, it is almost uncontrollable in full auto. So troops (especially 'green' troops) would often fire off their entire combat load in the first few minutes of a fire fight! I have read that the VC noticed this and would deliberately only have one or two of their soldiers (especially in a ambush situation) fire semi-auto to get the US troops to fire most of their ammo right away and then be almost defenseless against the VC's attack/ambush! A three-round burst rifle (not full-auto) would theoretically reduce or stop this wasteful practice!
Great detailed illustrative work! I love details on thoughts and reasoning behind the actions. My brain is wired in a way that need to make sense of things by knowing the steps involved. Also helps me absorb the whole picture. Sweet programing!!!! Thank you for the video! Please keep up the good work. I appreciate you and you channel greatly. Love, peace, and harmony. Rev. Al G.
I feel kind of embarrassed having never actually learned how the trigger group works. Thanks for the video. Explains why there's so much less widgets in my AR trigger group than there were in the m16.
bigred2989 It stops firing. So, assuming you fired only one shot on burst mode, you'd only fire two shots the next pull of the trigger. This was one of the reasons that burst capable M-16s were phased out, so I've heard.
If Arnold Schwarzenegger were using one and stopped mid-burst, he'd say something like, "you have been terminated". It'll do exactly that, and your next pull will pick up where your last one left off. If you fired one first, the next would be two. If you fired two, the mext would be one. Best bet is to just hold onto the trigger until it stops, release, and hold again
Stealth The Unknown I see you tried too hard to be funny and failed miserably there, just answer the fucking questions, no forced jokes and that's that. Oh and fuck yourself.
Very very cool! I spent 4 years in the Marines and every time we would clean our M16 I would always try to figure out how exactly it worked. I had an idea but this is much easier to understand with this video
Thank you for making this. I'm a visual learner and having a moving model of this machinery really helps, plus you have the only demonstration of this on the internet.
Everyone, I can't reply if you have replying disabled! I'd love to answer a lot of your questions, but sometimes that reply button isn't there. If you can do it, allow replies. Thanks!
I know it's nine years old but this is an excellent video explanation of the three possible modes of an AR/M16/M4 trigger - semi-auto, auto and three round burst. Very well done. 👍
Excellent explanation and video. A fellow gunsmith and I were just discussing this subject and it's very helpful to be able to see it in action. Thank me for taking the trouble to do this.
I swear TH-cam can read my mind. I was having a conversation with a buddy on the rifle he used when he served. He told me that it was full auto and now it may use the three round burst. That is when I got to thinking about how the mechanism worked. A day later this pops up in my feed.
Back in 2013 I joined the Marine Corps, and in boot camp I disassembled my M16A4 and saw how the Semi-auto worked but while looking at the internals of the weapon and switching from Semi to Burst over and over, I was always bewildered by how burst fire worked with the only visual difference being the disconnectors being slightly ajar. Now I know lmao.
The M-16 only had full and semi auto but with very little practice you can easily get consistent 3 round bursts by touching the trigger just right when you are in full auto.
A good as explanation as any. You'd think it would be difficult, but this invention is just so simple and brilliant. They could also make a five round burst.
Wow thank you for taking the time to draw up an animated cutout of this. When I learned how auto and burst fire modes worked, I had to read a description which referenced still photos of the parts. I wish I had found this video sooner. I am very knowledgeable about firearms and their operation, so my friends always ask me, "How does this/that work". Since I don't own a full auto/burst rifle it gets kinda tedious having to paint the whole picture with words and internet photos. From now on I will use this video, so again, thank you.
I see you commenting this a lot. YES, I DID make this model myself, the only thing downloaded was the software I used to make it and any still photo references to draw from.
Excellent video. I think a lot of people talk about how much better 3 round burst is than regular full auto (it does have practical advantages, but one should be using full auto for bursts anyway, it just takes more training...) without realizing that it is a bit more complex mechanism to make, more parts to break or have something go wrong etc... That being said it's a pretty well designed mechanism that works well and isn't prone to failure.
This is one of the best and most Informative videos I’ve ever seen. Thank you so much for making it and keep on making videos. Your animation was fantastic and your explanation was clear, concise, and easy to understand. Thank you again
theres litterally like no 3 round burst videos on youtube and i am personally way more interested on how that works then i am on how full auto works. would love to be able to shoot an original m16 burst design one day but i live in new york so i wont get my hopes up
I just found this video. Great job, great explanations and your narrations were outstanding! I like that you took your time and explained it thoroughly!
fantastic video, never knew how this worked, but it would have been nice for visual representation of problems with the 1, 2, or 3 shot problems you can run into depending on where the cam is when not all 3 shots are fired, or when switching from single to burst
Thanks for the vid, still hard to find a vid on how 3 round bursts work. Really cool to see it in action with this program. Always been curious about it, such a simple and effective design.

btw, I love the animation. .really simplifies explanation. . I'd love to see an animation on the "lightning link" or "registered auto sears" for the AR.. another cool animation would be the glock fssg endplate that drop in and make standard glock into select fire ...those things are just so amazingly simple by design but have to be really well made to exact dimension due to timing of the breech locking up
funshootin1 i'd be interested in looking into that. I know how the 18's FA works, but I imagine the endplate selector works similarly.
Colt had another patent for a burst fire trigger group for the M16A1 - US4004496A from 1977. It's more complicated and I don't think it was adopted for use. I haven't ever seen one, but there may be some old timers out there that have. I'm very familiar with the burst fire group discussed in this video. Genius design, to be sure. Great explanation!
Wow man you have some pretty badass computer graphics skills! Great rendition and explanation! Outstanding video. -Cheers
No he doesn't have any "computer graphics skills"; he downloaded this design it's free for anyone to download, he didn't make it.

I had a malfunction once where my M4 was placed on semi. It fired when I pulled the trigger and then fired again when I released. Your video helped me understand what happened. The metal on the front part of the trigger, the sear, probably wore down. Disconnector caught the hammer, but upon release of the trigger, wasn't caught by the sear and the hammer sprung forward and wasn't caught. Thanks.
Fantastic video! Great explanation. Like the physics program too. Very cool.
Very cool indeed! Thanks for watching :)
never in my 5 years or so of being an absolute full time firearm enthusiast have i seen this explained so clearly. i always could understand the mechanics of a full-auto AR rdias, but have never seen a working model of the burst "cam?" in action like that. thanks for vid, learned a ton. subscribed
i will share with anyone who is interested enough to listen
xxskizzumxx Please do! And thanks for the support! This questing has been bugging me for YEARS, so I went to some of the most remote and hidden places on the net, even sites that were NOT in German or English (my two primary languages) to demonstrate the mechanics. With those many months of being a cybernaut on a quest to find the answers, I finally did, and put this together to demonstrate it.
Great video. Very detailed and informational.
I'm a former SF/18B. This was an excellent demonstration and explanation. Well done, young man. De Oppresso Liber.
I'd just like to point something out where you were slightly off, you said that if the hammer fired off too early, it could result in catastrophic malfunction, which is wrong, it will simply ride the bolt forward and not fire, because it doesn't strike the fireing pin with enough force, which is easily demonstrated by tying down your seer, or bumpfiring to fast, it is an action known as outrunning the gun.
+Bradley Homer this is true, but I was trying to make the point that it is dangerous and unreliable to have the hammer follow the bolt forward. Though it is rare that this causes any kind of out-of-battery firing, it HAS happened when "outrunning the gun." The results have always been undesirable in those circumstances
I've tried to make guns fire like that, but I could never get it to happen.
+Bradley Homer I was just getting ready to point this out.
+Jason Cox this is so wrong, but I'll elaborate further since you are sort-of on the right track. It won't fire after the first shot if you remove the disconnector, as the hammer will ride the BCG forward (bolt carrier group.) However, some people have allegedly filed the interface on their disconnectors to temporarily catch the hammer, but cause it to slip soon after, effectively turning the mechanism into a rate reducer. This mod is highly illegal, though, and I'd advise against it.
+Jason Cox fair enough. I'd imagine if the firing pin wasn't shrouded, the issue could occur. I'd venture the disconnector had bad engagement rather than being missing.
Finally this explains why everytime I had to shoot 3round sometimes I'd get 2 or 1 shots during a burst. I let the trigger go too early sometimes. I always wondered exactly why my issued m4 did this.
"design feature"
Very cool video dude. Well made and informative. Thanks. Thumbs up.
Great explanation, thank you for showing the basic mechanics and not rambling on about other things in the video. Concise and to the point. I'd like this twice if I could.
Yes, thank you! I did my best to avoid tangents and things of the sort, as they always agitate me when watching tutorials or educational videos. Thanks for watching!
Mark Scoble It has been a challenge to find the information on the Stoner Burst Kit. I have had very little luck on the HK or Sig variants, but I have tried. maybe some day I'll get some ffl and own a few, or the U.S. Govt. will become a bit more compliant to the constitution. Who knows?
***** If you check out Gun Disassembly 2, it comes with a Sig 552 model in which you can get a decent look at the burst system.
***** If you are interested,I have an HK book that describes the burst mechanism of MP5 in detail.The book has 28 pages and it has pictures.This animation was very good and I would love to see the burst mechanism of MP5 in a video like this.I can send you the book, if you give me your email.
I also have a question.I already knew how the Stoner burst mechanism works, but I was never able to wrap my head around how the movement of the hammer rotates the cam backwards.You said that it is some kind of ratched mechanism.Actually there is a spring between the hammer and the cam, but I cannot understand how this spring rotates the cam backwards.If you know how this works,I would be thankful if you can help me to understand it.
Catching Fire from what I've seen, there are actually little indexes on the inside of the cam that the spring engages on when the hammer is pushed backwards, but the spring slips over them when the hammer drops. it's essentially a ratchet mechanism with two moving parts: the hammer and spring, and the cam wheel.
I'd LOVE to see that book! Thanks for offering to show me :) find me at stealththeunknown@yahoo.com
***** Thank you,it's more clear now.I didn't know how the spring engages with the hammer and the cam.Still if you know of a book,site or some pictures that depicts this,please send me a link.
I have send you the book on your email.It would be great if you can make an animation of the HK burst action,since the HK system is more complicated and more difficult for people to visualize.
I will take a look and work on it. Thanks!
If anyone is curious, burst was initially introduced to let the shooter fire multiple rounds while not having to worry about when to let off the trigger. Which decreases mental effort and increases endurance in long firefights.
Precisely! “Shotgun mode”, where it’s a short pattern - like full auto, but less “full.”
Ironically binary triggers basically do the same job but in a more intuitive way. But nobody tell the ATF that.
When the M16 was first issued to troops in the field (Viet Nam), they would sometimes 'panic' and fire full auto as the 'norm'! Because the rifle is so light weight, it is almost uncontrollable in full auto. So troops (especially 'green' troops) would often fire off their entire combat load in the first few minutes of a fire fight! I have read that the VC noticed this and would deliberately only have one or two of their soldiers (especially in a ambush situation) fire semi-auto to get the US troops to fire most of their ammo right away and then be almost defenseless against the VC's attack/ambush! A three-round burst rifle (not full-auto) would theoretically reduce or stop this wasteful practice!
Great detailed illustrative work! I love details on thoughts and reasoning behind the actions. My brain is wired in a way that need to make sense of things by knowing the steps involved. Also helps me absorb the whole picture. Sweet programing!!!! Thank you for the video! Please keep up the good work. I appreciate you and you channel greatly.
Love, peace, and harmony.
Rev. Al G.
Thanks man! that means quite a lot to me :)
Thanks for this - the explanations I'd read didn't really make sense without the visual. So, thanks a ton!
Excellent video. And a very nice model
I feel kind of embarrassed having never actually learned how the trigger group works.
Thanks for the video.
Explains why there's so much less widgets in my AR trigger group than there were in the m16.
What happens if you let go of the trigger mid burst?
bigred2989 It stops firing. So, assuming you fired only one shot on burst mode, you'd only fire two shots the next pull of the trigger. This was one of the reasons that burst capable M-16s were phased out, so I've heard.
If Arnold Schwarzenegger were using one and stopped mid-burst, he'd say something like, "you have been terminated". It'll do exactly that, and your next pull will pick up where your last one left off. If you fired one first, the next would be two. If you fired two, the mext would be one. Best bet is to just hold onto the trigger until it stops, release, and hold again
Stealth The Unknown I see you tried too hard to be funny and failed miserably there, just answer the fucking questions, no forced jokes and that's that. Oh and fuck yourself.
Charles Ferdinand Damn, why are you so hostile?
@@Tatusiek_1 he is probably a liberal
Very very cool! I spent 4 years in the Marines and every time we would clean our M16 I would always try to figure out how exactly it worked. I had an idea but this is much easier to understand with this video
Oorah! Glad to help out, dude
Outstanding illustration (motion sickness-inducing in-and-out zooming notwithstanding).
yeah, I do apologize for my lack of experience panning properly when I made this. I've gotten better about that. thanks for watching!
Thanks for sharing. One more life question answered.
Thank you for making this. I'm a visual learner and having a moving model of this machinery really helps, plus you have the only demonstration of this on the internet.
Everyone, I can't reply if you have replying disabled! I'd love to answer a lot of your questions, but sometimes that reply button isn't there. If you can do it, allow replies. Thanks!
You just click on the comment to comment on it
Excellent video. I've paid for gunsmithing courses that didn't explain this properly. Well done. Thank you.
That's surprising to me. I would imagine they's do a better job.
Educational. #engineering
excellent video with clear explanation. TH-cam needs more of these.
I know it's nine years old but this is an excellent video explanation of the three possible modes of an AR/M16/M4 trigger - semi-auto, auto and three round burst. Very well done. 👍
Thank you sir!
Excellent illustration for my simple pea-brain. I had no idea how that worked. Now I understand it completely. Thank you.
Thank you for your effort. The simulation was very helpful. Great job explaining the 3 round burst.
Excellent explanation and video. A fellow gunsmith and I were just discussing this subject and it's very helpful to be able to see it in action. Thank me for taking the trouble to do this.
+TwentythreePER glad I could provide a visual diagram to demonstrate this with :P
I swear TH-cam can read my mind. I was having a conversation with a buddy on the rifle he used when he served. He told me that it was full auto and now it may use the three round burst. That is when I got to thinking about how the mechanism worked. A day later this pops up in my feed.
probably the phone hearing keywords to feed the algorithm. they collect information from you constantly to recommend things that may be relevant.
I think it's absolutely amazing to learn about these little feats of engineering that are so clever. Thanks dude
Excellent video...it couldn't have been more simplified and technical. Very hard to balance both...well done!
Back in 2013 I joined the Marine Corps, and in boot camp I disassembled my M16A4 and saw how the Semi-auto worked but while looking at the internals of the weapon and switching from Semi to Burst over and over, I was always bewildered by how burst fire worked with the only visual difference being the disconnectors being slightly ajar. Now I know lmao.
The M-16 only had full and semi auto but with very little practice you can easily get consistent 3 round bursts by touching the trigger just right when you are in full auto.
Hit-and-release, yeah
What a fantastic modeling. Greatly appreciated by the educational community.
Great vid. I'm impressed by the quality of your simulation. It makes understanding much easier than someone just pointing at things with a pencil.
A good as explanation as any. You'd think it would be difficult, but this invention is just so simple and brilliant. They could also make a five round burst.
certainly, but it would be a tad more difficult to do properly with the angle of rotation that the hammer goes through.
Thanks for the video.
Simple. To the point. With visual explanations.
Perfection.
The best explanation I have seen. You need an award.
clear and simple explanation how this works! All thumbs UP!!!
Wow thank you for taking the time to draw up an animated cutout of this. When I learned how auto and burst fire modes worked, I had to read a description which referenced still photos of the parts.
I wish I had found this video sooner. I am very knowledgeable about firearms and their operation, so my friends always ask me, "How does this/that work". Since I don't own a full auto/burst rifle it gets kinda tedious having to paint the whole picture with words and internet photos. From now on I will use this video, so again, thank you.
He didn't "draw" anything; he downloaded this design it's free for anyone to download, he didn't make it.
I see you commenting this a lot. YES, I DID make this model myself, the only thing downloaded was the software I used to make it and any still photo references to draw from.
I was a little skeptical of the video, but it was super impressive, great job!!
Yeah, this is weaponized autism it its finest 👌 I appreciate the kind words, and hope you learned what you needed to!
Weaponized autism?? Did Greta thurnberg make this video🙊😂🤣😜
Excellent video. I think a lot of people talk about how much better 3 round burst is than regular full auto (it does have practical advantages, but one should be using full auto for bursts anyway, it just takes more training...) without realizing that it is a bit more complex mechanism to make, more parts to break or have something go wrong etc... That being said it's a pretty well designed mechanism that works well and isn't prone to failure.
This is one of the best and most Informative videos I’ve ever seen. Thank you so much for making it and keep on making videos. Your animation was fantastic and your explanation was clear, concise, and easy to understand. Thank you again
I always wondered how this worked. Knew there were a lot of parts, but didn't get how it worked together. GREAT VIDEO!!!!!!!
Very rarely do I find a video as informative as this. Thank you.
Glad it was helpful!
What a great video. Excellent visual representation of an M16/M4 fire group. Great explanation. Thank you for this video
Much appreciated!
Thanks for making this video. I was wondering how the 3 round burst would operate.
theres litterally like no 3 round burst videos on youtube and i am personally way more interested on how that works then i am on how full auto works. would love to be able to shoot an original m16 burst design one day but i live in new york so i wont get my hopes up
one can always hope. Or, you know, move.
I just found this video. Great job, great explanations and your narrations were outstanding! I like that you took your time and explained it thoroughly!
Very nice video, you strike the critical balance between under explaining and over explaining, if that makes sense. Thoroughly enjoyed it.
It does make sense. Under-explanation is a pet peeve of mine, and over-explanation always gets annoying. Thanks for watching!
Many thanks! Always wondered how a burst worked and here it is. May the Force be with you!
Well done Stealth. This is the first-ever cad/cam video I've seen on the burst mechanism.
fantastic video, never knew how this worked, but it would have been nice for visual representation of problems with the 1, 2, or 3 shot problems you can run into depending on where the cam is when not all 3 shots are fired, or when switching from single to burst
neat video I like the animation. 3 round burst much more complicated than I thought.
Thanks for the vid, still hard to find a vid on how 3 round bursts work. Really cool to see it in action with this program. Always been curious about it, such a simple and effective design.
Freaking cool graphic animation of the 3 AR fire selections.
