I couldn't resist…..had to throw a "Super Safety" into my 5.56 pistol build. It DID require, however, the installation of an adjustable gas block (Seekins) and a Geissele Super 42 kit w/H3 buffer for everything to function the way it should. Oh, I also threw in an enhanced firing pin (Rubber City) just for kicks. Man, THIS could get expensive REALLY fast!!
