The Daniel Defense 10.3” 300 Blackout S2W® barrel is designed with a strength to weight profile (Daniel Defense's Heavy Barrel), a 1:8" twist rate, and a pistol length gas system.Cold Hammer Forging of barrels has been known for decades to produce the most accurate, longest lasting rifle barrels obtainable. The Cold Hammer Forging of barrels is accomplished through intense hydraulic pressure applied at opposing angles by carbide steel hammers. During the hammering process, a mandrel is inserted into the bore while the carbide steel hammers shape the barrel around the mandrel creating the chamber, the lands, and the grooves. In addition to the aforementioned benefits, the Cold Hammer Forging process creates a defect free bore and the most consistent chamber possible.Stripped Barrel 1.25lbs  Barrel w/ LPG1.33lbs All Daniel Defense cold hammer forged barrels are made from start to finish in our state-of-the-art facility located in Black Creek, GA.
