The Rugged Suppressors 3-Port Muzzle Brake (brand part no. MB001) is a 5/8×24-threaded muzzle device built for .308/7.62 NATO rifles, cutting felt recoil and muzzle rise while giving the barrel a solid platform for a Rugged suppressor mount. Three top-relief ports vent gas upward and to the sides instead of straight back at the shooter, which keeps the line of sight clearer for faster follow-up shots. Because it shares Rugged’s mounting interface, it lets the same suppressor move between multiple rifles once each barrel wears a brake. It’s a standalone rifle accessory, not a suppressor, and mounts with common gunsmithing tools.

Key Specifications

• Machined for a 5/8-24 tpi thread pattern, it fits the standard .308-class muzzle thread found on most AR-10 and bolt-action .308 barrels.
• Rated for .308 / 7.62 NATO, matching the cartridge pressures and bore diameter it’s designed around.
• An overall length of 1.5 inches keeps the brake compact and minimizes added barrel length.
• The 3-port design vents propellant gas upward and laterally to reduce muzzle climb during rapid fire.
