Rimfire silencers cater to some of the smaller (and dirtier) calibers - and for that reason, most rimfire silencers feature the ability to be broken down and cleaned thoroughly. Using a rimfire silencer makes shooting and hunting that much more enjoyable.
Rimfire silencers, because rimfire calibers usually produce so much more dirt and debris when shooting, frequently are designed to be taken completely apart to remove the filth and clean up the device. On many, even the baffles will come apart for cleaning. Many users employ small cleaning devices like ultrasonic cleaners to quickly and easily remove the grime without having to perform much manual cleaning.
