FN Hammer Forged 18″ Barrel Rifle Length are using the same proprietary high-grade Chrome Moly Venadium steel used in FN’s venerable machinegun barrels.
Produced to handle the punishment of sustained fully-automatic fire.
Each barrel is Magnetic Particle tested to ensure that it is free of micro-stresses or flaws.
This results 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.
This 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.
