The Otter Creek Arms OTB Muzzle Brake is a one-piece, integrated suppressor adapter and muzzle device built from H900 heat-treated 17-4 stainless steel and finished in black nitride. Designed specifically for shooters running OPS 12th model suppressors like the OCM5 or AEM5, this brake combines a functional muzzle device with a quick-attach mounting system that eliminates the need for custom barrel work or special collars. If your rifle has a 1/2×28 threaded barrel with 0.75" or smaller outside diameter and a minimum of 2.05" of exposed barrel from the shoulder, you can install this brake without any modifications.
The integrated approach means you get recoil mitigation and suppressor mounting in one component, streamlining your setup and reducing the number of parts in the system. The black nitride coating provides corrosion resistance and a professional finish that holds up to hard use in the field or at the range. Unlike some two-piece systems, this single adapter simplifies maintenance and reduces potential failure points.
Installation is straightforward: the brake ships with a shim kit for timing alignment, and shimming is the only approved method for timing this device—no crush washers. The shim kit is included and engineered to get your suppressor perfectly indexed without additional gunsmithing.
