FN America 18″ 5.56 Cold Hammer Forged Barrel CHF NATO Rifle AR15 Fabrique Nationale Herstal AR-15
Description:
FN AR15 barrels are hammer forged using the same proprietary high-grade Chrome Moly Vanadium steel used in FN’s venerable machinegun barrels produced to handle the punishment of sustained fully automatic fire. After forging, each barrel is Magnetic Particle tested to ensure that it is free of micro stresses or flaws, resulting in consistency and quality in every barrel shipped from the factory. The bore and chamber are chrome lined to help resist corrosion and provide resistance to heat erosion which greatly improves barrel life and reliable chambering/extraction. The M4 style feed ramps and barrel extension provide consistent feeding and the matte black Manganese Phosphate finish resists external corrosion and oxidation.
Cold Hammer Forging of barrelshas been known for decades to produce the most accurate, longest lastingrifle barrels obtainable. The Cold Hammer Forging of barrels isaccomplished through intense hydraulic pressure applied at opposingangles by carbide steel hammers. During the hammering process, a mandrelis inserted into the bore while the carbide steel hammers shape thebarrel around the mandrel creating the chamber, the lands, and thegrooves. In addition to the aforementioned benefits, the Cold HammerForging process creates a defect free bore and the most consistentchamber possible.
