James BSeries Posted November 1, 2021 Report Posted November 1, 2021 I am new to AR building , So I ask this stupid question. Will any 308 Bolt Carrier cycle in a Armalite Ar10 -B upper. I know about the difference of the Bolt an Barrel Extension. Must match and the head spacing, an not to mix the Bolt carriers an Bolts parts.
