Re: M40a1 build guide
I think I read here that GAP uses something else on their M40A1 spec builds because true black oxide isn't a very good finish, is real toxic in its application, and that only one outfit in Arkansas does it any more.
Re: M40a1 build guide
Is there a modification to the magazine follower to allow the M40A1 to hold 5 rounds or is that 5 rounds including one in the chamber?
