The Daniel Defense 18” 5.56mm NATO S2W barrel is designed with a heavy strength to weight profile and a Mid-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.
All Daniel Defense cold hammer forged barrels are made from start to finish in the state-of-the-art facility located in Black Creek, GA. In keeping with Daniel Defense's heritage of not cutting corners, all cold hammer forged barrels feature a forged chamber and heavy phosphate exterior coating or Salt Bath Nitride Finish. These barrels will prove themselves to be more accurate and last longer than a barrel that has cut or button rifling.
