The Griffin Armament Dual-Lok Mini Brake (DLM556) is a compact, high-performance muzzle device engineered for 5.56/.22 caliber firearms with 1/2x28 threading. Built from tough 17-4PH stainless steel and coated in a wear-resistant QPQ Nitride finish, this minimalist brake integrates directly with the Griffin Armament Dual-Lok quick-detach (QD) suppressor mounting system. Sixty precisely machined mounting grooves paired with the mount's two out-of-phase locking positions deliver 120 effective locking positions total, guaranteeing a tightly secured suppressor with consistent point-of-impact (POI) retention. At only 1.42 inches in overall length and 2.3 ounces, the DLM556 adds minimal weight and profile to the host firearm compared to most competing suppressor mounts. Integrated compensating ports actively reduce muzzle climb and felt recoil, while a sacrificial baffle protects the suppressor's internal components to extend its service life. A shim set is included for precise timing during installation.
