Silencerco - Sparrow SS - .22LR Suppressor

The 22Sparrow is the first silencer in the world to offer the patent pending Multi Part Containment (MPC) technology, which allows the 22Sparrow to be easily disassembled for cleaning and maintenance after heavy use.

Because the .22 LR round is not copper jacketed, molten lead and carbon debris will explode into the silencer when the projectile exits the muzzle. After some time, it is possible for a .22 suppressor to fill completely with lead and become heavy and ineffective. To avoid this issue, .22 silencers must be disassembled for cleaning and regular maintenance.
MPC technology has made it possible for shooters to disassemble the 22Sparrow easily after heavy use without the need of tools.

Until Silencerco introduced the 22Sparrow, the only .22 silencers that could be disassembled for cleaning required a cleaning every 50 to 200 rounds. However, often the components of those silencers would be fused together and unable to come apart. Competitor products on the market have baffles in their .22 silencers that must be removed by twisting the outer tube around the baffles and/or sliding the outer tube off of the baffles. When the lead and carbon debris adhere to the inner wall of the outer tube and fill the spaces between the baffles and the outer tube, there is simply too much buildup of fouling and lead to remove the outer tube in that manner.

Silencerco solved this maintenance issue with MPC technology and made it possible for shooters to disassemble the 22Sparrow easily after heavy use without the need of tools. MPC technology revolutionized take-apart silencers by containing the lead and carbon debris to prevent the debris from reaching the outer tube. This innovative design is achieved by applying two tube halves before sliding the outer tube on the rest of the assembly. When disassembling, the outer tube can be easily removed, and the tube halves are free to pull away from the baffles without having to rotate or slide. Just pull off the tubes, clean the components, and reassemble.
