FN Herstal - Wikipedia

By using the most advanced automated manufacturing processes, FN barrels are certain to be of the highest quality at the most efficient cost. Their hammer-forged, chrome-plated barrel is legendary in the firearms industry for its precise accuracy and long life. Our button-broached barrel is of such high quality, a breaking-in period is not required, and it will shoot accurately right out of the box.

Today, FN produces a wide range of small arms for the U.S. military: M4/M4A1 carbines, M16 rifles, MK19 grenade machine guns, and M249 SAWs, as well as the MK46, MK48, M240, M240C, M240D, M240E1, M240H, M240B, and M240L machine guns.

FN AR15 barrels are hammer forged using the same proprietary high-grade Chrome Moly Vanadium steel used in FNs 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.
