16in rifle gas is finicky - Criterion Barrels AR-15 Hybrid Rifle Gas System Barrel

This barrel is very accurate. Better than I will ever be able to shoot that is for sure. I have not been having very good success with my rifle cycling so far though. I first tried a superlative arms piston kit and only could get it to run at all suppressed with the gas setting wide open. I now have it set up DI, but my last range trip it would not lock back on an empty mag unsuppressed. I put the lightest possible spring on my JP silent capture assembly and will see what happens.

Criterion makes great products. I'm sure I'll get this to run after toying with it.
