I don't know what buffer or spring I am using at this time maybe RRA. I just have a standard low profile gas block made by Bison Armory. They do offer adjustable but they don't come standard. I am not sure what type of gas system, I would have to call ask for specifics. I already called Bison Armory about it, just waiting on the blacksmith to reply back.
When I used the 85s. This is what occurs. Firearm shoots projectile. The bullet would eject but next cartridge from magazine would not chamber. I would have to charge manually to chamber a round.
The 110s were fine
