This is a discussion on A Black Rifle Gas Piston VS Direct Gas Impingment Animation ~ VID within the Defensive Rifles & Shotgun Discussion forums, part of the Related Topics category; ...
The concept has worked for the Russians for decades.
I have always felt like a blow back or operating gas rod system may be more reliable
due to ease of maintenance and lack of carbon build up. Still, one cannot deny the success of the gas system of the AR. Someone brought it to my attention that carbon is actually desirable, as it is a natural, dry lubricant, although the build up should be kept in check.
Pooping where you eat is never a good idea.
Yeah the big prob with the AR design is that it "does it's business" where it eats. Bad, bad, bad. As Jules said in Pulp Fiction, "I don't trust an animal without the sense to disregard its own feces." :)

DI AR and M-16's seem to have worked well over time. While a piston system may be better in some cases DI isn't all that bad. Great vid Qkshooter.

Cool. Either way seems to, and has proven to work.
Not really a "Yea" or "Nay" thread as I pretty much just put the VID on the forum as an educational visual illustratration of the difference between the two systems. It's decent animation.
Of course & as always though feel free to "weigh in" with any on topic comments or personal experiences on either.

I think if our military ever issues a new battle rifle, It will probably be a gas piston operated rifle.
It's hard to argue that keeping dirty gases and heat out of the heart of a rifle is a bad thing.
Don't believe what you hear and only half of what you see!
What is the biggest disadvantage with a Piston design? I know with the AK, you have much more rearward mass, meaning more recoil. (Correct?) Same principle with piston ARs? Why would you not want one? Price?
The video does sum it up nicely. Thanks for sharing!

I don't have to clean my Sig 556 carbine with every use, to remain caveman club reliable, and it'll run bone dry if need be requiring just minimal lube (I use a light grease) without failing after one or three mags.
AK reliability with FN FAL style improved AK mechanicals, and it's accurate...too.
Just sayin. ; p
