Sparrow is disappointing Login/Join

Thinking about sending my Sparrow back for a fix or something as it is not quiet and never has been. Took it to the Class III dealer last week and they shot it and then shot a new one and the difference was very evident.

I have shot less than a box of sub-sonic ammo in it and it dos not appear to be dirty. Same results on rifle or pistol.

Ideas or suggestions welcome.

I’d try giving SilencerCo a call, they’ve always been happy to help when I’ve reached out.

Not sure if their upgrade program for the Sparrow is still active, but I did find this video explaining it.

SilencerCo Sparrow Upgrade Program

When I searched for it on Google, I found a reference explaining the program, but when clicking the link… It brought me to a page not found.





Best of luck!

That is interesting. Some 22lr cans are more prone to FRP than others. How did you shoot it?

FRP can build over time. IE if you shoot one round set the gun down and bring the target back it may be part of the culprit.

Also, some cans do perform better with a bit of sludge in them. Have you cleaned or prepped the bafflestack in anyway? Ie Socing them hot in atf or is it just plain jane stack?

Up untill my failure, my 2lb AAC pilot was still quiet as can be. It was stupidly quiet through out its life. Much more so than many other 22lr cans. It also had very little FRP. Down side is that it was a sealed can. and the crap built up to failure.

The Sparrow is a monocore, one of the commonly held beliefs is that monocore’s have more FRP on pistols than traditional stacked baffles.

At least in my experience this seems to hold true. While my Sparrow does great on rifles, I’m not a fan of it on pistols. Truth be told, knowing what I know now I’d pass on the Sparrow altogether. That said I’d call SiCo as well, they’re very good to work with; had a defective MAAD mount they swapped out for me.



Success always occurs in private, and failure in full view.

Complacency sucks…

The Sparrow was one of the first .22 cans I bought after a 15-20 year break from NFA stuff. It was a relatively new idea with the monocore and was quiet but easily beat by the AWC and the classic Element II baffle stack cans. I think it's too short to be effective as a monocore, it needs to be more like the Liberty Regulator, one of the quietest cans ever when run wet.

I have an original Aluminum Sparrow which works well on rifles and pistol. I declined sending it back for the upgrade after people reported more FRP and that it wasn't as good on rifles as the original.

There are better 22 cans these days, but I'm outta the biz and am happy with my Sparrow and B22 HTA.

I have a Sparrow in jail right now, please don't harsh my buzz. LOL

What did SiCo say about the upgrade, if anything?

You will be happy with your Sparrow. While there are some cans out now that test at less dBs the difference is negligible to non-existent when you are listening 12-16 yards away. I shoot my Sparrow wet with RemOil and you can hear the difference it makes. Enjoy!

I have an AWC Archangel, two Sparrows (one is stainless) and a Dead Air Mask. By far, the Mask is the best. I'd like to play with the Q erector...shooting one with a single shot life card 22LR was a ton of fun (as ridiculous as it was)

There are a few people who will open your sealed can, put a threaded end cap or do both ends so you can take it apart. Liberty might and there are others... Google "jailbreak suppressor" (or silencer).
