Sig Sauer Clutch-Lok Shouldered QD Flash Hider - 90 Degree Shoulder, Steel Matte Finish

The Sig Sauer Clutch-Lok Shouldered QD Flash Hider is a dual-duty muzzle device built for shooters running Sig's SLH or SLX suppressors. This 90-degree shoulder quick-detach mount threads onto non-Sig Sauer barrel profiles and pulls double duty: it provides secure, repeatable suppressor attachment while also functioning as a flash hider when you run your rifle unsuppressed. The steel construction with matte finish is built to handle the rigors of hunting, tactical training, and range work without the extra weight of a dedicated suppressor housing.

What makes this Clutch-Lok design useful is the simplicity of the interface. Rather than fumbling with different mounting solutions or walking a tight line between suppressor compatibility and bare-barrel performance, you get one device that handles both jobs. The 90-degree taper is the spec for aftermarket and non-Sig barrels—if you're running a factory Sig SAUER rifle with their proprietary Taper-Lok profile, that's a different part. Installation is straightforward, and the QD mechanism means your suppressor detaches cleanly and reattaches with zero play.

Keep in mind that suppressors, muzzle devices, and their combinations are tightly regulated at federal and state levels. NFA registration, tax stamps, and local compliance requirements vary widely, and they're entirely on you to verify before purchase or installation. This is a precision component—make sure it matches your barrel spec and local law before you commit.
