After reading and trying to understand I think that since I will be shooting my AP5 suppressed probably at least 95 percent of the time using 147gr Subs I’m gonna get an 80 degree locking piece. This will help reduce back pressure/blowback and should also reduce the stress on the BCG H buffer making it last longer as well.
