MasterPiece Arms, manufacturers of the MAC 10 inspired MPA Defender Series and the MPA Protector Series subcompact pistols, gave fans and customers the opportunity to name the first series of their new MPA .22 sound suppressors. The best name that followed in the MPA tradition of Protector and Defender product series names would win one of the first MPA 22 suppressors produced and designed entirely by MPA.

The units are designed to be fully serviced and cleaned by the user. A disassembly tool and instructions are included with every suppressor. The first of the three is the Sentinel named by winner Scott Wellman of Roanoke, VA. The Sentinel is a .22 suppressor in a K-baffle design with six baffles made from 7075 aircraft grade aluminum.
