The Armaspec Rook Micro Compensator, Black (brand part no. ARM4511-BLK) is a compact 1/2×28-threaded compensator built to address recoil and muzzle control on a pistol without adding much weight or size. Armaspec made the Rook only slightly longer than a standard thread protector, then cut slotted gas ports into the body for effective recoil reduction in that small package. Its compact size and minimal added weight keep it largely invisible under concealed-carry clothing, setting it apart from bulkier compensator options. User-friendly wrench flats make installation straightforward, and the low-profile shape keeps the pistol compatible with a wide range of holsters.
