SilencerCo Sparrow 22

The SilencerCo Sparrow 22 is the suppressor that started it all. It was the first suppressor SilencerCo ever built, and after fifteen-plus years it remains one of the most popular rimfire suppressors on the market. Built entirely from 17-4 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 full-auto rated on .22 LR. The Sparrow 22 mounts directly on standard 1/2x28 threads and is compatible with SilencerCo's Delta Adapters for non-standard thread patterns.
