Sig Sauer SL76258X2425DEGM Clutch-Lok QD Muzzle Brake, Black Stainless Steel, 5/8"-24 tpi Threads, 7.62mm, 25° Taper

The Sig Sauer Clutch-Lok QD muzzle brake is a quick-detach mount designed for shooters running Sig's SLH or SLX suppressors on 7.62mm rifles. This isn't just a suppressor adapter—it pulls double duty as a functional muzzle brake when you run your gun unsuppressed, helping manage recoil and keeping your sight picture steadier between shots. It threads on via 5/8"-24 tpi, fits Sig's proprietary 25-degree taper shoulder interface, and comes finished in black stainless steel for durability in the field.

Fast suppressor attachment and removal is the whole point of quick-detach systems, and the Clutch-Lok delivers on that promise. Whether you're hunting, running suppressed precision drills at the range, or keeping your setup quiet on private land, you get seamless transitions between suppressed and unsuppressed configurations without re-zeroing or tool fiddling. The 25-degree taper is purpose-built for SIG SAUER Taper-Lok barrels; if your barrel is a different manufacturer or uses a 90-degree shoulder, verify compatibility before ordering.

Like all NFA components, suppressors and their mounts are federally regulated items. You're responsible for confirming local and state laws in your jurisdiction before purchase and use. Sig's engineering on this piece keeps things simple and robust—no complexity to break, just straightforward QD functionality and honest recoil management when the can comes off.

Frequently Asked Questions

Will this mount work on non-Sig barrels?

The 25-degree taper is designed specifically for SIG SAUER Taper-Lok barrels. If your barrel uses a different manufacturer's shoulder or a 90-degree taper interface, you'll need a different QD mount. Sig makes a 90-degree version for non-Sig barrels if that's your setup.

What suppressors does this Clutch-Lok work with?

This mount is designed for Sig's SLH and SLX suppressor models. Verify your suppressor model before purchase to ensure compatibility.

Does this work as a muzzle brake alone?

Yes. The Clutch-Lok functions as a muzzle brake when your suppressor is not attached, providing recoil reduction and helping maintain sight picture during unsuppressed fire.

What thread pitch do I need?

This model is 5/8"-24 tpi, standard for 7.62mm rifle calibers. Confirm your barrel's thread pattern before ordering.
