SILENCERCO SPARROW 22 SUPPRESSOR – RIMFIRE SILENCER, .22 LR THROUGH 5.7X28MM
The SilencerCo Sparrow 22 is a rimfire suppressor rated for .22 LR, .22 WMR, .17 HMR, .17 WSM, and 5.7x28mm, with full-auto capability on .22 LR. Built from 17-4 and 316 stainless steel at 5.08 inches and 6.5 ounces, the Sparrow was SilencerCo’s first product and remains one of the top-selling rimfire suppressors on the market. Sound suppression measures 112.7 dB on .22 LR, 124.5 dB on .17 HMR, and 127.7 dB on 5.7x28mm. The 1/2×28 thread mount covers the vast majority of rimfire hosts, and a wide range of adapters is available for pistols and specialty platforms. If you are searching for a compact, easy-maintenance rimfire suppressor that handles the full range of small-caliber cartridges, the Sparrow 22 has been the benchmark for years.
The Sparrow’s Multi-Part Containment (MPC) system and monolithic core design address the biggest maintenance problem in rimfire suppressors: seized baffles. The interior clamshells scrape clean with a nickel, and the monocore disassembles without tools or stuck components. High-volume shooters can run 2,000 or more rounds between cleanings. Rifle applications show no discernible first-round pop. Pistol applications have a slight first-round pop.
CAPITOL ARMORY’S OPINION
When the Sparrow came out, it was the rimfire suppressor everyone wanted. Shorter than most competing cans, solid sound numbers, and a cleaning system that actually worked. It is not the newest rimfire suppressor on the market, but it still delivers exactly what made it popular. The MPC and monocore design are the real differentiators here. Most rimfire suppressors get dirty enough that the baffles weld themselves together with carbon and lead fouling. The Sparrow’s design sidesteps that problem entirely, which matters a lot if you shoot .22 LR in volume.
At 112.7 dB on .22 LR, the Sparrow is hearing-safe and genuinely quiet. The 5.7x28mm rating at 127.7 dB is a useful bonus for FN Five-seveN and PS90 owners, and SilencerCo makes a dedicated adapter for the FN platform. The full-auto rating on .22 LR is not just a spec sheet line for suppressor collectors. If you run a semi-auto .22 at any real pace, the Sparrow will keep up.
