From the manufacturer

Daniel Defense Rifle Barrel Assembly/CMV/CHF/300BLK/1-8/S2W/PST 10.3in. 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. 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. In keeping with our heritage of not cutting corners all cold hammer forged barrels feature a forged chamber and highest quality exterior coating. These barrels will prove themselves to be more accurate and last longer than a barrel that has cut or button rifling.
