To complement my 5.7N pistol, I am thinking about putting together an AR upper, I can crank out the barrel from a Green Mountain blank, but not having seen in the flesh, I struggle a little abnout the receiver and what needs to be done accommodate the 30/50 rolund mags on top.
Has anyone done one from scratch? Please chime in.
Thank you.
