GRIFFIN Dual-Lok EZ Brake .45 Caliber 11/16x24 Threaded Muzzle Device

The Griffin Armament Dual-Lok EZ Brake is a .45 caliber muzzle device engineered for shooters who want a suppressor-ready platform without the weight penalty. Built for use with Griffin's Dual-Lok series silencers—including the Dual-Lok 5, Dual-Lok 7, HRT-556, and HRT-762—this 11/16x24 threaded brake interfaces directly with those suppressors while delivering noticeable recoil reduction on its own. At just 2.5 ounces, it's one of the lightest mounting solutions in the Dual-Lok ecosystem, meaning less mass at the muzzle and a more responsive feel downrange.

Construction is 17-4 PH stainless steel with a Black Nitride finish—the kind of durability you expect from Griffin. The brake features three radial slots that work together to mitigate recoil impulse, and the design requires no timing or indexing during installation. If you're running a suppressor-compatible .45 caliber rifle or pistol, the Dual-Lok EZ Brake gives you a functional muzzle brake now and a locked, repeatable platform for a suppressor later. The 13/16 standard socket wrench-compatible design means straightforward installation without special tools.

Whether you're setting up a dedicated suppressed rifle, optimizing an existing .45 caliber build, or bridging the gap between unsuppressed and suppressed shooting, the EZ Brake keeps weight down where it counts and locks up solid with minimal point-of-impact shift when paired with a Dual-Lok can.

Frequently Asked Questions

Will this muzzle brake work with Griffin Dual-Lok suppressors?

Yes. The Dual-Lok EZ Brake is purpose-built to interface with the entire Dual-Lok series, including the Dual-Lok 5, Dual-Lok 7, HRT-556, and HRT-762. When attached to a Dual-Lok suppressor, the retention ring ensures solid lockup with minimal point-of-impact shift.

Does the EZ Brake require timing or indexing during installation?

No. The radial slot design does not require timing. Installation is straightforward: thread it onto your 11/16x24 barrel and tighten with a standard 13/16 socket wrench.

What's the weight penalty compared to other .45 muzzle devices?

At 2.5 ounces, the EZ Brake is designed as one of the lightest mounting options available for the Dual-Lok interface, keeping muzzle-end mass minimal and your barrel more responsive.

Can I use the EZ Brake without a suppressor?

Yes. The three radial slots provide functional recoil mitigation on their own. The Dual-Lok interface simply gives you the option to add a compatible Griffin suppressor later without reinstalling the brake.
