  • anyone ever run the adams arms piston with the black rifle arms bolt carrier group?

  • Am I the only one getting turned on by watching this?

  • I'm guessing this is gas opperated?

  • @applejax89 Nope, its powered by hopes and dreams.

  • @NZXTInerTia SOunds like the most powerful gun of them all!

  • @applejax89 What gave it away, the fact that the gas visibly operates the action in the video?

  • Great video.

  • nice video!

  • arma de ar comprimido  a venda youtube.com/watch?v=ORqMOev4Jp­g

  • .357 viewers liked this video!

  • I personally perfer ak47 models cuz they almost never broke, are reliable, and very easy. American weapons sometimes fuck up.

  • @LyonLMS with the new piston uppers they are just as reliable and more accurate not to mention if you re calibrate it to 6.8 which blows 7.62by 39 out the water.

  • @LyonLMS Ak 47 is quiet old now, this works similarry. DI systems are good too, with proper maintenance.

  • @matt92hun What makes an old design a bad one? The AR-15 was originally designed in the 50's as well, and the current issue AKs probably have few parts in common with the original milled AK's. And the Kalashnikov operating system has little in common with a gas piston AR, it's a long stroke one and way simpler. It doesn't feature a bolt catch for example, but that's just fewer small parts which you could lose or break. :P

  • @moptim I love the Kalashnikov too, I just don't like when people compare everything based on the AR-15 to the XM-16E1.

  • good example

  • wouldnt that make more recoil

  • @mcdudly00 less due to not needing a buffer

  • Comment removed

  • Very good understanding of the weapon. Thankyou. thummbed up and subbed and fav;d

  • Great animation, the visuals speak for themselves.

    As for DI vs Gas-Piston ( non-biased ):

    1) Understand all options and decide which you would trust more with your life.

    2) In event of mechanical malfunction in combat, quick and simple restoration of weapon function is critical.

    3) Excellent physics and engineering on paper is not the same as real-world, combat situation performance.

    4) Arguing 'by the numbers' gets nowhere. In the field, it either works, or it doesn't.

  • very smart eng

  • I prefer the short stroke piston system over the direct impingement system because it's much cleaner

  • holy shit awesome i would be very thanfful if i can use some frames for my sorht action movie ? plz ;)

  • how is it that the cartridge ramps up into the chamber so easily, without jamming?

  • IAR has got a piston working. Way to go us

  • Can anyone answer my question?:

    What causes the bolt face to rotate and lock into place? I see that the "indent" on the left side of the upper is the space where the bolt locks, but what makes it rotate?

    Thanks in advance.

  • It reminds me of those M16s produced for the US army

  • i have a question , isn't the DI system more stealthy becausedon't have gas in the gas block ejected too?

  • so if i understand correctly, if the AR-15 is fitted with a piston it works the same way as an AK-47? And why wouldn't they use it in the first place? please respond, thnx

  • @maxim020408 If by "the same way" you mean "both use a piston", then yes, but there are a lot of other differences between the two guns, and a LOT of other guns out there that use pistons.

  • @agadhahab1 ok thnx, i know the scar uses a piston to the FN FAL to if i'm not mistaken

  • @maxim020408 cause a piston system adds alot of weight, and when eugene stoner was designing it the bureaucrats in the army made it an absolute requirement to make the M16 as light as possible. so he had to work around it, not that theres anything wrong with DI, its proven, while i hear somtimes that these piston ARs can be a little goofy.

  • things like a heavier barrel, brass deflector, better sights, forward assists. Those are improvements. This, as proposed here, is an attempt to change a design in its entirety.

  • wow great rotating bolt/gas operated dynamics shown here! geart job!

  • What program is this?

  • What program did you use?

    Is it Pro/E?

  • idk whats the big deal with that system, the AK has perfected that kind of system in their design. but the world makes a big deal over the AR getting one

  • @tmylve3495 just a cheap and effective marketing ploy..thats all. For over 40 years the AR has been doing a good job, now all of the sudden you gotta have a piston varient.

    its like what modern day rappers do to classic songs, copy it, change a few things (AKA shit all over it) and sell it.

  • @Alexn1067

    I believe that the whole point of the piston system is to reduce the amount of build up on the bolt. That looks to me to be a great idea. That carbon residue that builds up on the bolt because of the gas and pressure is difficult to clean for me anyway. In the piston system virtually all of the gas is leaving the front of the weapon.

  • @Alexn1067 lol too right mate

  • @Alexn1067 Yeah... you're right. Those mother fuckers at Colt should have never made the changes to the original 1911. The 1911A1 is just a marketing ploy and provides zero improvement over the original. And what's with all these beavertail and extended safeties?

    We should all resist clear improvements... because fuck change.

  • @strych97 to counter your sarcastic and bitter response. Let me just make the point that, there is a difference between improving and trying to fix something that isn't broken.

    The AR15 was originally designed with DI gas system. This was revolutionary at the time and set the AR15 apart from other self loading weapons. Its partly what gave it its unique identity. Stoner specifically chose that, not because he couldn't use a gas piston, but because it was a unique solution.

  • @Alexn1067 I see now! Because you have drawn a line at what things can and can't be changed, without causing that change to become a novelty, the piston operation (despite having a demonstrably positive effect on reliability) is relegated to the status of "marketing ploy", while an improved bolt and bolt carrier or extra power buffer spring, are legitimate upgrades that enhance reliability and/or function.

    It's good there are those in authority, like you, to decree arbitrary status upon things.

  • @strych97 for one, you don't have to be sniveling prick about it. My stance on it was in no way a slight towards you, so get the fuck over it.

    now back to the original discussion. The gas pistons have not contributed to any significant amount of reliability in the overall design other then heat reduction which makes a difference if you plan to use the platform as a sort of LMG, but in terms of a rifle, makes little difference. So yes its an unnecessary feature to throw in

  • @Alexn1067 There it is. My mind is expanding once again. Thank you for that!

    Now that I know an "unnecessary feature" is a defining attribute of something that is a "cheap marketing ploy", I guess those things like extended and ambidextrous safeties, match grade barrels, variable power recoil springs, etc., ARE gimmicks after all.

    You're probably right about it not contributing to reliability very much. I'm certain that's why all the most reliable rifles use DI systems.

  • @strych97 you seem to keep willfully missing the point. That is changes that enhance the design are improvements, changes that add little or nothing to the equation are "gimmicks" Like that extra feature the car salesmen told you that you needed on your car when in reality you didn't and it just added an extra few hundred bucks to the overall price.

    Talk to any expert outside of the companies peddling this "new" feature (which really isn't new at all) and they will tell you the same thing

  • @Alexn1067 Hmmm. So... something that improves the firearm, but only in certain ways, counts as a "design improvement" versus it being a "marketing ploy". That kind of sounds like what I said before. Are you sure you're an authority on this like you said? Wait nevermind, that was me. I'm so silly sometimes.

    Here's a fun one: watch?v=AGwkHktkTxU

    I'm sure that the results of this one test don't show a particular design flaw, though. Probably just bad luck for the DI gun.

  • @strych97 oh I see so you're an expert yourself because you saw a few videos online. Get the fuck outta here you parrot

  • @Alexn1067 You have me wrong. I'm a novice, learning from an authority, on the subject (you)! Of course, you still haven't educated me on how the piston systems are so much worse than a DI system. I really need to know all the advantages of a DI gun system over a piston system because I'm currently debating this topic with a piston-gun fanboy and I need the words of an authority on ARs in order to show how dumb he is.

    Please educate me. I beg you!

  • @strych97 The main advantage of the DI system is simplicity, less parts to break. Pistons are okay, but they add weight and complexity to the gun. And not all pistons are created equal, some actually will reduce the reliability. They make the bolt carrier to tilt in the receiver, this can cause the bolt to short stroke and fail to cycle.

    In principle pistons are better because they keep the gun clean and cool, but many don't work as well as advertized. But I don't think its worth fighting over

  • no need to be so asshurt, because I happen to think that you wasted your money on a useless feature, or maybe you didn't. In any case I don't get why you have such a hard on about it. You can disagree if you will, but conclude it and move the fuck on. You're starting to bore me

  • I'm more interested in how the locking lugs/camming sear works. Can you do a vid explaining it?

  • SOLIDWORKS? HEY DO A M1918 BAR .Hmmf MODERN COMBAT RIFLE MY EYE , GAS OPERATION , RECOIL OPS , BLOWBACK , NOTHINGS REALLY CHANGED IN OVER 110 YEARS , REFINEMENTS YES ALLOYS DAM STRAIGHT. BY NOW WE SHOULD HAVE BLASTERS (SCI-FI WEAPONS) NEURAL IMPLANTS FOR COORDINATION ENHANSMENTS PERFICT AIMING, PACIFICATION RAYS HAHA

  • @MasterBlasterMusic Have you tried to use both rounds yet in your AR ?

    I use all ammunition in my AR's 223 and 5.56x45 military surplus without any problems .

  • sooo the piston doesn't remain in contact with the bolt? The bolt travels farther than than the piston?

  • @importsstillsuck Correct. It's called "Short Stroke Gas Operation." The operating rod exerts enough force on the bolt to propel it rearward far enough to complete it's full cycle of operation. (IE ejection and feeding of the next round) Lay a coin on your table and strike it with another coin. The first con moves farther than the second. There's the short stroke principle in a nutshell. This is nothing new. It's late 1930's technology (M1 Carbine) adapted to late 1950's technology (M16)

  • @johnowenbeall ok, I've heard of short stroke systems, just didn't know that's all it was...thank you

  • This was awesome dude.Thanks man it really helped me visualize how the rifle works. :D

  • 0 dislikes, reflects on a job well done. :)

  • @MasterBlasterMusic If you bought a gun chambered in 5.56mm then you can shoot both 5.56mm and .223. If it is .223 you can't shoot 5.56 because of the higher pressure the cartridge produces. I own a piston 5.56 and shoot both regularly without problems

  • @flyhighkev Keep on shoot what your using nothing bad will happen to your AR .

    I have been doing just as you have with my AR's since 2000 and all my AR's are just fine .

  • I think the gas sisten is the best!

  • Interesting, probably one of the best if not the best video about direct impingement / gas piston system

  • @shankman2000 Well, It depends on what you're going for; Simplicity, or reliability. The direct impingement system on the AR-15 and it's derivitives, etc. is simpler and, because there's less parts recoiling/moving to the rear, typically easier on the shoulder.

    On the other hand, the Piston systems(such as on AK type firearms), thanks to the fact that a lot of the gasses and fouling from the propellant are kept away from the bolt assembly and chamber by the piston, tend to be more reliable.

  • I saw the Ak47 action video before watching this one. Is there any relevancy to the statement that the AR platform was never intended to be a piston gun? Do any of the AR piston guns out there, LWRC, Ruger SR556..... experience abnormal wear because of the piston action in comparison to say an AK47 which was designed to be a piston gun?

  • @Pivo000 I was lurking around the internet for this as well, and I found an interesting discussion on a forum (youtube won't let me post link). There is somebody who reppresests Addax tactical who says the pistons they use in their ARs are different and better and do not cause those carrier tilt. I would take this with a grain of salt as it was an official from the company and not a bunch of private users, though the rep made a good argument.

  • @Pivo000 Only in the begaining was there prolems with the piston convertions for the AR's.

    The problem was the gas key was cracking but now the bolt carriers are machined with the bolt carrier as a one pice unit .

    New production AR's don't see any problems with piston set up .

  • That is the same piston used in the M&P15 PSX and PS. I believe S&W has a legal agreement with Adams Arms for using their piston design which is a very good one BTW.

  • watching this gave me a realization of how genious an assualt rifle`s mechanics work.

  • This video enlightened me, thanks man

  • Ha, I used this video to win over someone who thought that direct impingement was a good system, this and the poops-where-it-eats way of telling the story.

  • this is a very well done 3d animation. very helpful.

  • most helpful i have ever seen

  • five star

  • I don't understand how the empty shell just pops out of the gun, or i can't see it.

  • is that its actual rate of fire? or is it semi automatic?

  • are there any downsides at all to using a short-stroke gas piston system like the one shown here?

  • @arandomperson3 some people might think it seems heavier. but the pros (cleaner, more reliable gun) outweigh the cons (slight increase in weight)

  • @tegopro86 How much of a weight difference can it be? I mean it just a thin piston system that's no thicker than a sharpie. I'm thinking about buying a bushmaster AR and getting a gas piston system installed.

  • @arandomperson3 i dont know. the piston system is just a steel rod about 11 inches long, i dont think thered be much of a noticeable difference

  • the piston system creates way more recoil no?

  • @123Cranker it makes a slight increase in the amount of mass moving around, so the recoil feels a little bit harder

  • by my thinking the gas piston wokings are more reliable but i aint sure

  • @sveqete96 Not much to think about; the gas tube transfers expanding gasses back into the gun internals, which can and will cause buildup from excess shooting without cleaning (and on pre-A4 models may cause a cook off.) The gas is more reliable because it diverts the expanding gasses used in cycling the next round away from gun internals.

  • @sveqete96 Yeah like with that AK-47. I'm still waiting for that to take off and become really popular. Should happen any day now.

  • Nice 3d animation, almost real except too much bullets inside a 30 capacity magazine.

  • Good work

  • Very educational.

  • @NavySEAL1942 - No, it is vented from the gas block at the front of the gun. You can see this in the animation as a puff of smoke at around 0:36 through to the end of the animation.

  • oh look... kinda like lwrc =/

  • Is the rate of fire slower using the Adams piston? Why can't someone just make a self blowback system for the ar15? pistons and gas systems make things complicated. it could be so much easier and more reliable, might lose a little accuracy, that's about it.

  • @traiter82 Because the AR-15 uses a locking bolt.

  • @traiter82 wrong man i got a piston in mine and it didnt lose any accuracy.have you EVER used one??

  • @allester99

    Your rifle is a sample size of ONE. It's a pretty well known fact that the mechanical accuracy between a piston and DI AR is different, with the former being slightly worse. However, it's nothing drastic, and most shooters aren't shooting to the capability of their rifles anyway, so the differences often aren't realized until the rifle is being benched and shot by a skilled shooter.

  • @opmike343 i installed the piston myself with the Adams Arms piston it works Flawless.I have heard of some other pistons malfuctioning like the ones made by HK.

  • Madman, does it work well with the 6.8mm SPC II chambered AR-15 rifles?

  • now i get it! great video!

  • wow, high quality models and render, plus very educational.

    five star'd and favorited.

  • That was truly amazing! Thanks for sharing! And I would assume this was done in 3D Studio Max?

  • no, It was done in Lightwave

  • Oh okay. Very cool none the less! :)

  • Thanks... more to come soon :)

  • Interesting.

    One thing I noticed: the bolt (the front part with the locking lugs) rotates into the wrong direction while the rest of the bolt and the connected cam pin move correctly.

  • Amazing, just wish it was a bit cheaper... not sure if the cost outweighs the extra cleaning with the traditional DI system.

  • Perhaps over time.... A lot of time... unless you also consider labor cost when cleaning your own rifle... I just finished my rifle, I don't yet know how hard cleaning will be but I heard it's a b**** :-)

  • @lizzieodonnell cleaning it so its functional doesnt take much, cleaning it so it is spotless...well..thats therapeutic for some of us
