All .308 AR designs are NOT piston driven. There are gas guns. Dpms for example.

Actually, Mist wolf is right. It's just a matter of where the piston is located. In the Stoner Expanding Gas System, the bolt carrier group IS the piston, since it reciprocates within the upper receiver. Versus an external piston system that reciprocates over the barrel.All .308 AR designs are NOT piston driven. There are gas guns. Dpms for example.
Very nice, Zero.
What're the specs on that bad boy?
Beats the hell out of me? He is still active here at THR, maybe he will share what he bought or maybe took a few days to think about it and decided against an AR 10 type rifle. Only he knows.Thread is almost 2 years old.
What did bigarm buy?
Well, at least no one told him to buy a Glock.
Hey OP, buy a Roni.
There.

If the Stoner system is piston operated, so is the AG42 and MAS49/56. Heck, even recoil-operated guns are driven by an expanding volume of gas in a cylinder thrusting against a moveable face. All guns are gas-operated, and all gas operations relies on cylinders. Brilliant, and super helpful.
Rather than trying to be clever to score points, the "piston," "DI," "recoil," "blowback" categories are --shock-- intended to help differentiate a large number of diverse mechanisms into groups more easily discussed for purposes of description or comparison. Animal, vegetable, or mineral. In such a mindset, the AR is clearly not a piston gun since there is no protruding rod or driving element located forward of the breech face, thus differentiating it from things like the SCAR or AK or CETME. A far more useful point of discussion than "in reality, all auto-loading guns are piston operated" (well duh; all bullets are pistons)
