We wanted to build an AR15 barrel using the finest blank and mass produce them to bring them to market at the most competitive prices. Our UltraMatch barrels start out as Shilen blanks and contoured to our specifications. We wanted the best balance between accuracy while keeping the weight down as much as possible. It also features Shilen's Ratchet Rifling which allows for flatter trajectories and easier cleaning.

Stubby and stout barrelReview by
Functions fine with SLR adj. gas block at turn 7 from full closed, Voodoo low mass bcg, Tac Com lightweight buffer. Accuracy is nothing spectacular, but the barrel's potential is not realized with my build due to lack of a magnified optic. I can't imagine very many barrels being stiffer than this one due to it's heft and short length. The barrel weighs 550gr (19.4oz). (Posted on 11/5/2016)
