Daniel Defense 5.56x45mm NATO M4 Contour 1 in 7in Twist 16in Cold Hammer Forged Barrel

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 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 barrels feature a forged chamber, chrome lining, and heavy phosphate exterior coating. They are all MP tested on-site and are available in multiple configurations which includes barrel only; barrel with Front Sight Base; and barrel with FSB, gas tube, and delta Ring assembly. These barrels will prove themselves to be more accurate and last longer than a barrel that has cut or button rifling.

Made in the USA!
