DRD 5.56 FN Hammer Forged Chrome Lined AR15 Barrel Kit

 

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.

 

These Amazing CHF barrels are extremely durable with a 20,000+ round service life. The barrels have a .750" gas block seat with a properly sized gas port and the muzzle is threaded perfectly concentric to the Bore with 1/2x28 threads. These CHF barrels are made to the Mil-Spec for the M249 SAW. These barrels are chambered in 5.56 NATO, with a 1/7 Twist Rate. The barrel blanks are the correct Certified CMV material and they are also Hard Chrome lined to the M249 SAW Mil-Spec, which is almost twice as thick as the Hard Chrome on a Mil-Spec M4. The End Result is a Rifle that can be Run Hard Day after Day! Each barrel is HPT and MPI. They have Mil-Spec M4 barrel extensions, Melanite finish on the outside (under the front sight base as well).
