Rearden
The Rearden SPB muzzle brake in 0.375 SR25 threads is a precision-engineered muzzle device built for shooters running suppressor-ready platforms. Built from 17-4 PH H900 stainless steel and finished in black nitride for durability and corrosion resistance, this brake pairs with Rearden's Plan B mounting ecosystem—giving you a modular, repeatable interface between your barrel and suppressor. The square-shoulder design ensures alignment integrity when you stack components, and the included shims let you dial in a perfect fit.
This is the brake for builders who care about precision. Plan B mounts are engineered for repeatability: your suppressor mounts and removes the same way every time, preserving zero and reducing the variables that come with traditional direct-thread cans. The nitride finish promotes a tighter seal, but like all suppressor systems, proper setup is non-negotiable. You'll want to torque the brake to 15–25 ft-lbs and Rockset it to your barrel, then ensure clean threads and tapers before mounting your suppressor at 10 ft-lbs. Use an alignment rod to confirm the whole system runs straight. That discipline pays off in sound signature and reliability.
The 0.375 SR25 thread spec fits the Crane Precision, Noveske, and other SR25-threaded uppers commonly seen on precision rifles and long-range setups. If you're already invested in a Q suppressor, note that Rearden advises Plan B use voids Q warranty—so verify your can before committing to this ecosystem. For hunters, precision shooters, and builders looking for a modular suppressor interface that actually repeats, this is the foundation that makes sense.
| Thread Type | 0.375 SR25 |
| Material | 17-4 PH H900 Stainless Steel |
| Finish | Black Nitride (67 HRC) |
| Mount Interface | Plan B Compatible |
| Shoulder Design | Square Shoulder |
| Shims | Included (not included with SR25/M110 variant) |
Yes—the 0.375 SR25 thread specification matches SR25 and M110 platforms. Just confirm your barrel threading before ordering. Note that shims are not included with the SR25/M110 variant of this brake.
This brake accepts any suppressor threaded for Plan B mounts. Rearden advises that using this system with Q suppressors voids Q's warranty, so verify compatibility with your can's manufacturer before committing.
Clean all surfaces, torque the brake to 15–25 ft-lbs, and Rockset it to the barrel. Use an alignment rod to confirm the system runs true. When you mount your suppressor, ensure threads and tapers are clean, then torque the can to 10 ft-lbs. The included shims help dial in a perfect fit if needed.
Plan B is a modular interface that repeats: your suppressor mounts and removes the same way every time, preserving zero and removing the variables of direct-thread systems. For shooters who change cans or remove suppressors frequently, that repeatability is a genuine advantage.
