I just scored a new Aero Precision stripped lower and am planning on making a retro m16 look alike. I was wondering if a surplus trigger would fit in my ar build. I will probably be using all new parts but just for personal reasons I would like to find a used m16 trigger that has the possibility of being in vietnam or somewhere used in combat to go in it... is this a possibility? are they hard to find? will it work?
