anybody have any idea on the quality of these lowers,i know they're cheap enough,and i have bought a few of SFRC's own lowers,i just cringe when i see NEA on anything,but for the price,if they are good,,i'd pick up a few,can't have to many,and i'm not one to worry about the prohib bull####,as the only thing they'd get is a small aluminum square with the serial number,NOTHING else.
