Sharps bro's livewire is a more traditional style ar15 receiver, but still unlike anything else out there with looks all its own: heavily flared mag well, ambidextrous bolt release, a stepped transition between trigger guard and mag well, threaded bolt catch pin, threaded rear takedown pin recess and extremely clean lines all around.Each livewire starts life as a 7075 aluminum billet that is first heated to 800 degrees and then forged into a near final shape with a custom tool and the pressure of a 4100 ton press.Type: StrippedCaliber: Multi-Caliber
