The Sig Sauer Clutch-Lok QD Muzzle Brake (brand part no. SL55612X2890DEGM) is a 5.56x45mm NATO muzzle device cut with 1/2×28 threads that doubles as a quick-detach mount for Sig Sauer’s 5.56mm SLH/SLX suppressors. Sig Sauer machines the shoulder interface to a 90-degree taper matched to SIG Taper-Lok barrels, letting shooters attach or remove a suppressor in seconds while gaining reduced felt recoil whenever the can comes off. It is a straightforward way to run one muzzle device that performs whether the suppressor is mounted or not.
