This is the lower receiver I assembled for my new AR 15 300 Blackout

Rifle. It is identical in every way to the "standard" 5.56 mm AR 15

lower. The bolt carrier group and charging handle are on a paper

towel...just waiting for me to apply a couple of drops of lube oil.

The upper is in a different vise so I can attach the free-floating

rail and backup sights to the barrel nut.



No one cares about your penile extension, idiot.Well, donnie the dicklicker would.
