Re: After Market Piston Kits for AR-15
I HAD an adams arms piston kit. Installed by adams arms, and snapped 3 pistons. Kept sending the upper back and forth. After 3 pistons, despite good customer service, I said screw this, switched back to DI, and now have a reliable stoner designed rifle again. Too bad the thing chewed the crap out of my brand new upper even WITH a one piece bolt carrier that "prevents" carrier tilt. That's my mileage, your's may vary. I will never piss on stoner's grave again.
Also: ruined my mil-spec charging handle, one buffer tube, chewed up a second, chewed up the buffer area of the lower, created cam-pin drag (bolt spring supposed to prevent) lots of marks inside upper where cam pin dragged and inside the CH sliding area.
