The Sparrow 22 was designed with simplicity, durability, and user serviceability as its core objectives, and has the quietest 10 round average of any silencer in its class. Patented Multi-Part Containment (MPC) technology facilitates ease of disassembly and reassembly - an essential function of rimfire suppressors. The internal MPC construction uses two half tubes that pull away from a monolithic core, which ensures that the Sparrow 22 will remain easy to clean after extended periods of use with notoriously dirty rimfire ammunition.
