Wasn’t sure what to expect - Kaw Valley Precision OPMOD Hybrid-K Linear Compensator

It works surprisingly well for .22 cb shorts, kind of like a puff.
For CCI velociters 40 gr, sounds similar to high velocity .22 lr. Without compensator.
Aguila 38 gr is slightly quieter than without the compensator, but not quiet.

I have it on my cricket .22 pistol with 10” barrel.
