Rearden SPB Features The Rearden SPB is machined from steel and heat treated for a finish that resists wear from repeated firing cycles and harsh field conditions. Its compact 1.73 inch overall length keeps the compensator close to the muzzle helping preserve the natural balance of a precision rifle build. Threaded at 5/8x24 the SPB fits common large-bore barrel threads without requiring a separate thread adapter. At a bore size of .50 it is purpose built for heavier caliber rifles that generate substantial muzzle rise and recoil. Weighing only 2.30 oz the SPB adds negligible weight to the front of a rifle which means shooters do not sacrifice handling speed in exchange for recoil control. Its square plan design is engineered to redirect propellant gases in a way that reduces muzzle climb during rapid strings of fire. This makes the SPB a practical upgrade for shooters running larger caliber precision rifles who want faster follow-up shots. For anyone building a heavy-caliber precision rig the Rearden SPB offers a durable purpose-built compensator solution.
