Description:

Inspired by the Army’s DM-R rifle, this Stainless Steel barrel features 12 large flutes to reduce weight and aid in cooling. With nearly a full pound of weight removed from the first 12 inches of the barrel, where coincidentally, the majority of heat is generated, the surface area is increased by a whopping 81%. Barrel weight is reduced to just 2 lbs. 9 oz. The barrel is produced with match grade blanks in 1:8 twist yielding light weight and excellent accuracy needed for many applications.

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.
