Rearden Manufacturing Group Llc Dpb Muzzle Brake 0.375 1/2-28 Threads Square Shoulder Black
$80.10
The Rearden DPB muzzle brake is a precision-engineered adapter designed for shooters running Plan B compatible suppressor systems. Built from 17-4 PH stainless steel in the H900 condition, this .375-caliber brake with 1/2-28 threads provides a robust mounting platform for your suppressor stack. The square shoulder design ensures repeatable alignment, while the black nitride finish—hardened to 67 HRC—delivers both durability and a superior seal compared to standard finishes. If you're building a modular suppressor setup with an Atlas or Atlas XL can, this brake bridges the gap between your barrel and your silencer with dependable mechanical lockup.
Rearden's updated design features larger wrench flats on the rear, making installation and maintenance more user-friendly in the field or at the bench. The brake ships with shims, giving you fine-tuning options to dial in perfect concentricity when you run your alignment rod. Proper setup—torquing to spec and staking the brake to your barrel—is critical to suppressor performance and longevity. This is a component that demands respect and attention to installation detail, but when done right, it delivers the rock-solid platform serious suppressors require.
Installation is straightforward if you follow Rearden's protocol: clean all surfaces, torque the muzzle device to approximately 30 foot-pounds, then Rockset it to lock the threads. Once that's solid, mate your suppressor (torqued to roughly 10 foot-pounds) and verify alignment with a bore rod. The nitride finish contributes to a tighter mechanical seal, which translates to better suppressor performance over the life of your system. This brake is compatible with Rearden's Atlas and Atlas XL suppressors as well as other Plan B-pattern cans.
