I recently built a new AR SBR in 300BLK. It has a carbine-length gas system and is under-gassed, even when run with a suppressor. It will eject the casing, but not pick up the next round.
I need to increase the gas flow on this gun to get it to run well. Do I do this by drilling the gas port hole on the barrel? Drilling the gas block?
Please advise.
