Great setup - Adams Arms Standard Picatinny Block Piston Kit

I’ve been running an Adam’s arms piston on my primary AR for almost a decade and i love it. I’ve built three other Adam’s piston ARs and have had the best results with the mid length system; it’s been 100%. I haven’t quite got my rifle length build fully reliable as will short stroke some times. I run an anti tilt gas tube and have seen zero signs of wear.
