Daniel Defense Barrel Assembly 5.56mm 1:7 Twist 11.5-inch Government

Daniel Defense AR-15 Pistol Barrel Government Contour Features:

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 cold hammer forged barrels feature a forged chamber and heavy phosphate exterior coating. They are all MP tested on-site and are available in multiple configurations which includes barrel only (stripped); barrel with front sight base; and barrel with Low Profile Gas Block. These barrels will prove themselves to be more accurate and last longer than a barrel that has cut or button rifling.
