FN America 14.7" Hammer Forged Barrel - 5.56mm NATO - Carbine-Length Gas - 1:7

FN America 14.7" Hammer Forged Barrel - 5.56mm NATO - Carbine-Length Gas - 1:7

Engineered to the uncompromising standards demanded by combat forces around the globe, the FN America 14.7" Cold Hammer Forged Barrel represents the gold standard in AR-15 durability, accuracy, and relentless reliability. Forged from the exact proprietary Chrome Moly Vanadium (CMV) steel used in FN's legendary military machine gun barrels, this platform is specifically designed to handle the thermal punishment and barrel wear of sustained, rapid fire. Whether you are assembling a dependable duty carbine or a lightweight, maneuverable pin-and-weld rifle build, this barrel provides the rock-solid foundation required for mission-critical operations.

Every barrel undergoes individual Magnetic Particle Testing (MPI) to guarantee a flawless, stress-free micro-structure before being fitted with an ultra-durable chrome-lined bore and chamber. This protective internal barrier defends against corrosive residue and extreme heat erosion, ensuring reliable chambering, smooth extraction, and extended service life over tens of thousands of rounds. Paired with factory-cut M4 feed ramps and protected by a weather-resistant manganese phosphate exterior, the FN 14.7" barrel delivers military-grade performance directly to your platform.

Features
