Description

The Faxon Firearms Duty Series barrel is a 16-inch button-rifled AR-15 barrel constructed from 4150 CMV and finished in Black Nitride. It is chambered for 5.56 NATO (.223 Remington) and uses a 1:8 rate of twist to stabilize a broad range of bullet weights. The HBAR profile balances rigidity for consistent performance with manageable weight, and the barrel is threaded at the muzzle for user-specified muzzle devices.
