Revolutionary SIG SAUER muzzle brake enables quick and simple attachment of suppressor to firearm. Taper-Lok Fast-Attach System with Muzzle Brake optimizes alignment, improves accuracy, reduces point of impact shift and doesn’t require any shims. Taper-Lok mount is also extremely simple to install, transforming an hour project into a 5-minute job. Available in multiple thread pitches and calibers, this muzzle brake self-centers the firearm and suppressor, which reduces group dispersion. It’s also available in a sub-caliber mount to enable true multi-caliber versatility, such as using the SRD762 suppressor on a 5.56-caliber firearm. It has a low profile yet is effective at reducing recoil and works best on SIG Taper-Lok-shouldered barrels, but is also backwards compatible with traditional, 90-degree shouldered barrels. Note: 5/8"-24 version is a two port brake. 1/2"-28 is a one port brake.
