  1. turned blank for competition Ar15 barrel 4 Star Review

    Posted by on 11th Jun 2019

    Turned a raw blank into a heavy profile Ar15, 20” barrel. First day out testing loads and 25 rounds down the barrel, it shot a 5 shot 7/16” group. 4 of 5 were 1/4”. Can’t attach a pic of group or I would. This was my first ar15 barrel build so I went with an inexpensive blank. I had read good things about Green mountain barrels and this build confirms the accuracy. I am turning my second Green Mountain blank now!
