The Sparrow™ 22 was designed with simplicity, durability, and user serviceability as its core objectives. 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.  Additionally, the Sparrow is rated for full auto fire and multiple calibers up to 5.7mm.
