Even big bird could put it on!! - Presma AR Buffer Tube Receiver End Plate Castle Nut

I had no issues and they look great!!If you use the right tool it usually works out better.Colors are a little off tho as the blue � was just slightly lighter than the pics but it matched my trigger guard nicely.Your never going to match everything perfect anyway.The silver is real nice and gives some contrast to my stainless steel barrel.If you don't have any sense like this other guy I'd recommend passing & build some LEGO'S.
