Sig Sauer Clutch-Lok QD Muzzle Brake 5.56mm 1/2x28 Black Stainless Steel

The Sig Sauer Clutch-Lok QD Muzzle Brake is a versatile quick-detach muzzle device engineered for 5.56mm rifles. Built from stainless steel with a black finish, it threads onto standard barrels with a 1/2x28 thread pattern and features a 25-degree tapered shoulder that provides a positive registering surface for repeatable suppressor alignment.

This Clutch-Lok device pulls double duty as both an effective standalone muzzle brake and a quick-detach mount for Sig Sauer SLH and SLX suppressors, offering quick and simple attachment of your suppressor in the field. The shouldered taper design ensures a secure fit, while the brake porting reduces felt recoil and helps keep the muzzle flat when running unsuppressed.

Designed and manufactured to Sig Sauer's standards, the Clutch-Lok QD is an ideal companion for shooters running SLH or SLX suppressors on 5.56mm platforms, and equally useful as a high-quality quick-detach muzzle brake on its own.
