    AR rifle and bolt carrier cutaway demonstration

    I love this guy's channel and want a bcg like this.

    Stoner was a genius.

    Not really, the gas system was terribly designed. Piston AR's run much cooler and cleaner.

    It's really an inferior design to the AK or M1A.

    It improved with the addition of the forward assist and dust cover but wasn't perfected until the gas system was replaced with a piston drive .

    It's apparent some aren't familiar with the fact that the Stoner system (both ar10 and 15) are indeed piston systems. Instead of a heavy and harmonic inducing op rod, the bolt itself inside of the bcg IS the piston.

    Note Stoner patented the system as piston driven, not DI.

    The AR's/M16's as originally tested and eventually given to the US military were direct impingement, not gas piston driven.

    The example in the OP is DI, not GP driven.

    The example in your video is not either.

    The gases are recirculated back into the upper via a gas tube that empties them into the BCG and upper.

    This causes rapid heat buildup and excessive fouling.

    This is an actual piston driven AR.



    Review: Sig Sauer Model 516 Gen 2 Piston-Driven AR - AllOutdoor.com



    The heat and fouling don't make it into the BCG or upper like they do with the original system allowing them to run far cooler and cleaner.

    Actual piston driven AR's are the future, not the original Stoner system who's only advantages were weight and cost of manufacturing.

    The Stoner system has less recoil and less barrel whip. Making it more accurate and easier to manage FA.

    That certainly can't be demonstrated with data. "Felt Recoil" depends on many factors but the calculations are pretty easy. The PD systems put more weight forward over the barrel and weigh a few more ounces overall which gives them the advantage in any recoil calculation.

    The Piston system actually stiffens the barrel's resistance to "whip".

    For precision shooting the Piston System is far superior which is why it's so easy to make one that will shoot sub MOA with a much lighter barrel than is required on the DI systems.

    Expert may disagree and do but many agree that the PD's are more accurate for that reason.

    I currently own quite a few of both types and have for many years and my accumulated data strongly supports this.

    Pick up an off the shelf Sig 516 or 716 (Or similar quality PD AR) and compare it to any off the shelf DI gun and test them both with the same types of ammo under varying conditions and see what you come up with.

    Another good article.

    Indeed and that was one of its major breakthroughs- controllable full auto fire.

    I've never fired an automatic M14 but apparently it wasn't so good.

    That must be why they are still in use or were until very recently by SOF's.

    The Rangers refused to ever give up their M14's for decades because they were so effective.

    The only modification needed for controllable full auto fire was a proper muzzle device.
