Bottom line for me, I trust my life to non piston guns.
Because they have inherent flaws or you just have not owned any? I am a novice trying to determine if I even want to own a black gun. I have been looking at the IWRC R.E.P.R.. It's a 308 piston gun.
I have fired several AR's of the impingement design and they were incredibly accurate at 100 yards, open sighted, even with me behind them.
