Product Description The Rearden Mini Muzzle Device (Plan B) is a precision-engineered, compact muzzle device designed to serve as the interface between your threaded barrel and a Plan B-compatible suppressor. Featuring a 1/2-28 thread pitch and a 0.456" bore diameter with a square shoulder design, this mini device ensures proper alignment and a secure fit every time. The durable nitride finish delivers outstanding corrosion resistance and a sleek, low-profile black appearance. Installation requires the use of an alignment rod to confirm the entire system is set up correctly, with the muzzle device torqued to 15-25 ft lbs against the barrel shoulder and the suppressor torqued to 10 ft lbs for a firm, aligned connection. A must-have component for any shooter building or upgrading a suppressed rifle platform around the Rearden Plan B mounting system.
