Faxon Duty Series 300 Blackout 10.5" Gunner Barrel

Faxon Duty Series 300 Blackout Barrel

The Faxon Duty Series 300 Blackout barrel represents serious engineering for a caliber designed specifically for suppressed shooting and short-range combat applications.

Key Features

• Caliber & Length: 300 Blackout, 10.5" barrel optimized for subsonic and suppressed fire
• Twist Rate: 1:8 twist stabilizes a wide range of 300 Blackout ammunition, from lightweight supersonic loads to heavy subsonic rounds
• Finish: Black Chrome Mag Phosphate coating provides superior corrosion resistance and durability
• Gunner Duty Series: Purpose-built for professional and serious sporting use

Performance Characteristics

The 300 Blackout cartridge was engineered for short-range effectiveness with suppressed fire. This 10.5" barrel length maximizes velocity while maintaining the compact profile that makes the caliber practical. The 1:8 twist rate is the sweet spot for 300 Blackout, reliably stabilizing both lighter supersonic ammunition and the heavier subsonic loads that truly shine with a suppressor.

Faxon's Black Chrome Mag Phosphate finish is harder and more corrosion-resistant than standard parkerizing, making it an excellent choice for a duty-grade barrel that will see regular use and cleaning.

Ideal For

• Suppressed AR-15 builds
• Home defense platforms
• Tactical training and competition
• Shooters seeking reliable subsonic performance
