Silencerco SS "White Sparrow"

Silencerco SS "White Sparrow"

Limited Edition "White" version of the Silencerco Sparrow.


The SilencerCo Sparrow was originally designed in 2009, then quickly updated to the current stainless Sparrow SS.  At that time, it completely changed the way people thought about rimfire suppressor maintenance - and put SilencerCo on the map as a company.

Before the Sparrow, rimfire suppressors were either sealed (i.e. they didn't come apart for cleaning); or, they had to be cleaned frequently in order to avoid having them seize up.  By introducing a Multi Part Containment (MPC) sleeve into the design, the Sparrow was able to come apart easily by hand.

Although it redefined what was expected from a suppressor as far as maintenance, the Sparrow also became known for having a noticeable "First Round Pop".  As a result, many manufacturers (including SilencerCo) started moving the best design concepts from the Sparrow into other models to improve overall performance.  Now, thanks to the Sparrow, providing ease of maintenance is a requirement for all the top selling rimfire suppressors.

On top of being extremely easy to clean, the Sparrow also supported multiple higher pressure calibers: like .22 Mag & .17 HMR.

Because of its innovative history, the Sparrow continues to be one of the most popular rimfire suppressors on the market.

From the Manufacturer

The SilencerCo SS Sparrow 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.  Threaded for the standard 1/2x28 pitch, the Sparrow is a great option for virtually any rimfire application.

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.

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.

The outer tube is uncoated and polished satin stainless steel.

    I use this lil' guy on my stainless 10/22 Ruger and my Browning 1911-22 pistol. Flawless on both. I threaded my Savage HB 17hmr but have had so much fun shooting the .22lr I have yet to try it out.

    Fantastic, easy on, off and easy to clean. Run it on my stainless 10/22 and run my black one on my browning buck mark. The hosts run without any problems with high velocity or sub sonic.
