| Comment | This Barrel is a 16" Heavy contour 300 BLK OUT .308 barrel rechamberd for the 7.62 X 39 to take advantage of the vast variety of bullets available that are .308 diameter for Subsonic Loadings. This load work flawlessly in the AR 15 cycling the bolt to hold open on the last shot with the full length stock and full length rifle buffer spring. |
