Griffin Armament
The Griffin Armament Dual-Lok EZ Brake is a lightweight muzzle brake engineered for shooters running Griffin's Dual-Lok suppressor line. Threaded 3/4x24 for .45 caliber rifles, this brake serves dual duty: it reduces recoil impulse during unsuppressed fire and acts as the quick-disconnect interface for Dual-Lok 5, Dual-Lok 7, HRT-556, and HRT-762 silencers. Unlike many muzzle devices, it requires no timing—you thread it straight on, making installation fast and foolproof.
Built from 17-4 PH stainless steel and finished in black nitride, the EZ Brake tips the scales at just 2.5 ounces, keeping your rifle's overall system weight low and the barrel nimble. The three radial slots do the recoil-cutting work without the complexity of a timed design. The tapered Dual-Lok retention ring locks the brake solid to your barrel, with minimal point-of-impact shift when you swap between suppressed and unsuppressed fire—a real advantage if you're testing loads or switching between hunting and range days.
Installation is straightforward: a standard 13/16-inch socket wrench gets the job done. If you're already invested in the Dual-Lok ecosystem or planning to be, this brake gives you a clean, repeatable platform for both muzzle control and suppressor mounting without the weight penalty of heavier options.
| Caliber | .45 |
| Thread Pattern | 3/4x24 |
| Weight | 2.5 ounces |
| Material | 17-4 PH Stainless Steel |
| Finish | Black Nitride |
| Overall Length | 1.4 inches |
| Spline Diameter | 1.075 inches |
| Mount Diameter | .93 inches |
| Installation Tool | 13/16-inch socket wrench |
The EZ Brake interfaces with all Dual-Lok series silencers, including the Dual-Lok 5, Dual-Lok 7, HRT-556, and HRT-762.
No. The Dual-Lok EZ Brake is a no-timing design, meaning you thread it on and tighten it down—no orientation adjustments needed. Installation requires only a standard 13/16-inch socket wrench.
The brake weighs 2.5 ounces, making it one of the lightest quick-disconnect muzzle devices available and keeping your suppressor system light and your barrel responsive.
The tapered Dual-Lok retention ring and solid lock-up are designed for minimal and repeatable POI shift, so switching between suppressed and unsuppressed configurations has minimal impact on your zero.
