The Rearden SPB 0.375 1/2-28 Square Plan B Muzzle Brake is built for shooters who want a compact, suppressor-ready device with clean, square shoulders for secure mounting. Machined from stainless steel and finished in a durable black nitride, this SPB model is designed around the Plan B ecosystem and offers a precise .375 bore with 1/2x28 threads for compatible barrels and suppressor adapters.

This muzzle brake is ideal for range use, training, and general-purpose rifles where you want reduced recoil and a solid interface for Atlas, Atlas XL, or other Plan B compatible mounts. Its compact profile keeps overall length in check while still providing effective gas redirection.
