The LMT 4-Port Regulator Muzzle Brake (brand part no. R-RMB5824762) is threaded 5/8×24 for .308/7.62-pattern rifle barrels and uses the same four tunable gas ports as LMT’s 5.56 brake to manage recoil and muzzle rise on the harder-kicking .30-caliber platform. Machined to LMT’s rifle-line tolerances, it threads on true and holds up to the added recoil impulse of .308-class cartridges. It’s a straightforward upgrade for .308/7.62 AR-pattern rifle owners who want a flatter-shooting, more controllable gun.

Key Specifications

• Threaded 5/8×24, the standard pitch for .308/7.62-pattern rifle barrels.
• Four tunable gas ports redirect propellant gas to manage recoil and muzzle rise on .30-caliber rifles.
• Machined to LMT’s rifle-line tolerances for a true, secure thread-on fit.
• Low-profile port geometry keeps the brake’s diameter close to the barrel profile despite the added recoil of a .30-caliber cartridge.
• Shares the regulator porting layout used across LMT’s 5.56 and .308 muzzle devices for consistent recoil control between calibers.
