Rainier Arms Rock Creek .223 Wylde Mid SDM Barrel - 16


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.
