Description
The SilencerCo Sparrow 22 is the suppressor that started it all. It was the first suppressor SilencerCo ever built, and after fifteenplus years it remains one of the most popular rimfire suppressors on the market. Built entirely from 174 stainless steel, the Sparrow 22 weighs 6.5 oz, measures 5.08" long, and carries a 1.07" outer diameter slim enough to clear factory iron sights on most .22 hosts. It is rated for .22 LR, .22 WMR, .17 HMR, .17 WSM, 22 Hornet, and 5.7x28mm, and is fullauto rated on .22 LR. The Sparrow 22 mounts directly on standard 1/2x28 threads and is compatible with SilencerCo#39;s Delta Adapters for nonstandard thread patterns.

How the MPC System Works
The Sparrow 22#39;s internal MPC (MultiPart Containment) design is what originally set it apart from every other rimfire suppressor available when it launched. To disassemble: unscrew the back cap, slide the outer tube off, and peel the two halftubes away from the monolithic core. Three Orings seal the system — two size18 Orings seat at each end of the monolithic core, and one size13 Oring engages the muzzle threads. The Sparrow 22 ships with all three Orings installed. Replacement Orings are available separately. Do not use solvents or ultrasonic cleaners on the outer tube, as finish damage may result; internal components can be cleaned with solvents, light abrasive media, or chemical dips.
