I am looking for a good BCG for my first build. I have been thinking BCM. Are the carriers MPI, HPT, and shot peened as well as the bolt? When looking for a bolt should I go with an m16/auto version or AR15 version? This is for a 20" barrel and have heard the m16 barrel is better for carbine AR's because of the higher pressures. Is there any reason not to go with the BCM BCG???
