Sig Sauer SL76258X2490DEGM Clutch-Lok QD Muzzle Brake - Black Stainless Steel, 5/8"-24 TPI Threads, 7.62mm, 90° Taper

The Sig Sauer Clutch-Lok QD muzzle brake is a dual-purpose accessory designed for shooters running Sig's SLH or SLX suppressors. This black stainless steel brake threads onto 7.62mm barrels with 5/8"-24 TPI pitch and uses a 90-degree taper interface—making it compatible with non-Sig barrels that share that geometry. When your suppressor is mounted via the quick-detach system, it functions as the QD interface; remove the can and you've got an effective muzzle brake that meaningfully reduces felt recoil and muzzle rise, improving shot control and follow-up accuracy.

If you're building a 7.62 rifle around a non-Sig barrel and want a suppressor-ready platform without the complexity of separate brake and mount components, this Clutch-Lok delivers both roles in one. The quick-detach coupling system makes attachment and removal fast and repeatable—no tools required. The 90-degree taper geometry is the key compatibility spec here; confirm your barrel matches this interface type before ordering. (Sig also produces a 25-degree taper version for their proprietary Taper-Lok barrels, so grab the right version for your setup.)

Remember: suppressors, mounts, and NFA-regulated devices come with serious legal requirements. It's your responsibility to verify compliance with federal NFA regulations and your local and state laws before purchase and use. Check with your FFL and local authorities if you're unfamiliar with the rules in your jurisdiction.

Frequently Asked Questions

What barrels will this 90-degree taper muzzle brake fit?

This brake is designed for non-Sig barrels featuring a 90-degree taper interface. Confirm your barrel's taper geometry before purchasing. Sig also makes a 25-degree taper version for their proprietary Taper-Lok barrels, so verify you have the correct version for your setup.

Can I use this brake without a suppressor?

Yes. The Clutch-Lok functions as a standalone muzzle brake when the suppressor is not attached. It provides recoil reduction and helps control muzzle rise, which improves shot control and follow-up accuracy.

What Sig suppressors does this QD mount work with?

This Clutch-Lok quick-detach system is designed for Sig's SLH and SLX suppressor lines. Verify compatibility with your specific suppressor model before ordering.

Is this product legal for civilian use?

Suppressors and QD mounts are heavily regulated under federal NFA law and vary by state and local jurisdiction. It is your responsibility to verify full compliance with all applicable federal, state, and local laws before purchase and use. Consult your FFL and local authorities if you are uncertain about the regulations in your area.
