I built an upper with a 13.7” Rainier Arms Rock Creek .223 Wylde Barrel. Carbine gas system and .750 gas block seat.
What buffer/ spring would you suggest to mitigate some of the recoil?
I know ammo often plays a role in this decision. I don’t have a “go to” or preference. Usually just 55 or 62 grain I suppose.
Thank you!
