FN AR-15 5.56x45mm NATO 10.5" M16 Profile Barrel

The FN AR-15 10.5" M16 Profile Barrel is a standalone barrel for compact AR-15 builds. It is chambered for 5.56x45mm NATO and is also listed for 223 Remington.

FN produces this 10.5" button-rifled barrel from US-sourced chrome-moly-vanadium steel manufactured to Mil-B-11595E specifications. Its right-hand 1:7 twist is paired with high-pressure testing and magnetic-particle inspection.

The M16 profile configuration uses a carbine-length gas system. An M4-style barrel extension and M4 feed ramps complete the established AR-15 interface features.

The bore and chamber are chrome lined for resistance to corrosion, heat erosion, and wear. The exterior has a matte black manganese phosphate finish.

This standalone AR-15 barrel is offered in New Condition.
