Sig Sauer Clutch-Lok QD 5.56mm 1/2x28 90 Degree Flash Hider - Black Stainless Steel

The Sig Sauer Clutch-Lok QD flash hider is a precision muzzle device that does double duty as a rock-solid quick-detach mounting point for Sig Sauer SLX and SLH suppressors. Machined from stainless steel with a black finish, this unit is purpose-built for 5.56mm rifles and features the standard 1/2x28 thread pitch found on the AR-15 platform.

The 90-degree tapered Clutch-Lok geometry delivers a tight, repeatable lockup with compatible SLH/SLX suppressors, while the ported design significantly reduces visible muzzle flash when running unsuppressed. The result is a single muzzle accessory that gives you both effective flash suppression and a confidence-inspiring QD interface for your Sig Sauer suppressor, with easy one-handed attachment and removal.

Built in the USA to Sig Sauer's exacting tolerances, the Clutch-Lok QD is an ideal upgrade for any 5.56mm rifle currently wearing a standard A2 birdcage or thread protector, opening a direct path to the company's premium SLX/SLH suppressor lineup.
