FN America AR-15 16" Mid-Length 5.56 NATO Barrel

FN AR-15 Barrel: Precision and Durability Redefined

The FN AR-15 barrel stands as a testament to the craftsmanship and engineering prowess that FN Herstal is renowned for. Forged from proprietary high-grade Chrome Moly Vanadium steel, this barrel shares its lineage with the legendary machine gun barrels designed to endure sustained fully automatic fire. This heritage ensures unmatched durability and performance under demanding conditions.

Each 16-inch barrel undergoes rigorous Magnetic Particle testing post-forging, eliminating micro stresses or flaws. This meticulous process guarantees consistency and quality in every unit that leaves the factory floor. The bore and chamber are chrome-lined, offering superior resistance against corrosion while mitigating heat erosion—a crucial factor in prolonging both barrel life and reliable function during chambering and extraction.

An integral feature of this design is the M4-style feed ramps coupled with a robust barrel extension, ensuring consistent feeding operations even under rapid-fire scenarios. Furthermore, its mid-length gas system provides an optimal balance between recoil management and cycling reliability.

The external matte black Manganese Phosphate finish not only complements its tactical aesthetic but also serves as a formidable barrier against corrosion and oxidation—preserving your investment through varied environmental exposures.

In summary, whether you're enhancing your existing rifle or building one anew, trust in FN's legacy of excellence embodied within this AR-15 5.56mm barrel to deliver steadfast performance when it matters most.
