452b264 Report post Posted January 7, 2019 ***SPF*** PSA 15 / FN CHF 16 INCH, MID-LENGTH DOUBLE CHROME LINED BARREL 5.56/223 AS NEW, TOOL CRAFT NICKEL BORON BCG (IF IT BREAKS THEY GIVE YOU A NEW ONE) magpul pro steel rear sight, nickel boron trigger and lighter high quality springs. $600 It might have 75/80 rounds through the barrel. FN AR15 barrels are hammer forged using the same proprietary highgrade Chrome Moly Venadium steel used in FN’s venerable machinegun barrels produced to handle the punishment of sustained fullyautomatic fire. After forging, each barrel is Magnetic Particle tested to ensure that it is free of microstresses 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.
