FN AR-15 Hammer-Forged Barrel
FN's AR-15 barrels represent serious manufacturing heritage. Each barrel is hammer-forged from the same proprietary high-grade Chrome Moly Vanadium steel used in FN's legendary machinegun barrels—steel engineered to withstand the punishment of sustained automatic fire.
Quality Assurance
Every barrel undergoes Magnetic Particle testing after forging to eliminate micro stresses and material flaws. This rigorous process ensures consistency and reliability in every barrel that leaves the factory.
