Frequently Asked Questions

1/2x28 is the industry-standard muzzle thread for most modern rifles and many pistols, including AR-platform rifles, bolt guns in rifle calibers, and numerous handgun models. Check your barrel's threading before purchase.

Is this mount suppressor-brand specific?

No. This is a universal mount that accepts any suppressor designed to fit 1/2x28 adapters. Compatibility depends on the suppressor's internal dimensions and design, not the mount itself.

Will this work on a short-barreled rifle or pistol?

Yes, 1/2x28 threading is used on both rifle and pistol barrels, including SBR and pistol platforms. Verify your specific barrel has 1/2x28 threading.
