BCM® 300 Blackout Barrels

• Continuous taper designed for optimal weight, balance, and performance.
• Fluted profile toward the rear near chamber area - Increases strength and heat dissipation.
• Tapered profile out front, for easier maneuverability.
• No sharp handguard cap shoulder for improved barrel harmonics and improved accuracy.
• This barrel will need a pistol length gas tube and a .750 gas block.
• Muzzle threaded in standard 30 cal (5/8x24)

BCM® has taken great care to ensure the best possible performance and interchangeability. However, due to the large operational range of 300 Blackout ammunition in the market place, BCM cannot guarantee function will all ammunition types in all conditions. These barrels were designed to run with a carbine buffer with subsonic ammo and a H3 buffer with high velocity ammo. Fine tuning may be required in limited instances based on ammo choices and buffer choices that works best for their application. BCM also recommends running the Crane O-ring (provided with all BCM Bolt Carrier Groups) over the extractor with 300 Blackout.
