AR15 - Piston vs. Impingment

[TN-popo]

Just remember though, the military weapons are made by the lowest bidder. There is some truth to what they say, though it is relative.

The standard military AR / M-series are made by Colt and FN (with rare exception). They are of better quality than many, if not most, commercial offerings when not worn out or beat to crap...which, of course, the manufacturer cannot control.

I plan to purchase a piston upper... but only because it will be used exclusively with a suppressor. As far as reliability is concerned, there may be some advantage... but realistically, shooters like us won't ever truly strain the function of a DI weapon, if it's properly put together and maintained. And from that standpoint, a DI gun is far easier/cheaper to maintain.

Thats odd. Due to the way the piston vents gas it's much louder with a suppressor than DI. It would be much cleaner though.

You don't get gassed near as much with a piston. The additional noise from the vented gas is negligible in the long run.
