anyone have any insight on this? This is the set up i'm running on my AR-pistol.

DD 10.3 1/7 barrel
AA piston sistem
H2 Buffer/carbine spring
Gemtech G5

I took it to the range to test it and whe i fired without the suppressor, on the full open piston setting. it will fire, sometimes eject the spent brass, sometimes it doesn't, and it will not feed the next round.

On the other hand it performed just fine on both gas setting with the suppressor on.

Could it be the H2 buffer or is the system not getting enough gas to push the bolt all the way back?

Suppressor increases  bore back pressure, so the gas action is seeing more pressure when suppressed.

So on that note, dropping the buffer down to a standard buffer may resolve the less gas pressure to the action when not suppressed problem.
