308 and 5.56 AR stock parts interchangeability
A friend just got a DPMS .308 AR. It is the M4 style one with colapsable stock and carbine gas system.
I was wondering if the buffer tube and receiver back plate is the same on those as a regular AR-15? He was asking me questions about changing parts but I wasn't sure if they were the same from one caliber gun to the next.
