Description
The Faxon Firearms Duty Series 7.5″ Gunner Profile AR-15 barrel is purpose-built for compact 300 Blackout pistol builds. Machined from 4150 Certified Gun Barrel Quality Steel and finished in QPQ salt bath nitride, this button-rifled barrel delivers the durability and accuracy expected from a duty-grade component.
Featuring a 1:8 twist rate and a pistol-length gas system with a .750″ gas block seat, the Gunner profile blends the weight of a Government contour near the chamber with a lighter profile under the handguard for improved balance and handling in short-barrel builds. The 5/8×24 threaded muzzle accepts a wide range of muzzle devices and suppressors.
Each barrel is stress relieved, air gauge tested, and MPI inspected to ensure consistent quality. Whether you are assembling a 300 Blackout pistol or SBR, this barrel provides the precision and reliability needed for both close-quarters and suppressed applications.
