KAK Industry PLAN B Big Hole Muzzle Brake 5/8x24 .375 Bore – AR-10, .308 Win, 6.5 Creedmoor

The KAK Industry PLAN B Big Hole Muzzle Brake is designed for shooters who want effective recoil reduction without excessive side blast. The enlarged .375" bore diameter safely accommodates .30 caliber projectiles (.308 Win, 6.5 Creedmoor, 6.8 SPC) with ample clearance for precision rifles and gas-operated semi-automatics. Its dual-chamber design redirects propellant gases to counter muzzle rise and felt recoil, improving follow-up shot speed and overall control during rapid strings of fire.

The 5/8x24 thread pitch makes this brake compatible with most AR-10 pattern rifles and bolt-action rifles chambered in .308 Winchester or similar cartridges. Constructed from heat-treated steel with a durable black oxide finish, the PLAN B brake installs with standard armorer's tools and a crush washer or shim kit for proper timing. The single-port design balances recoil mitigation with shooter comfort, making it suitable for both range work and field use.
