Inland PM-22
The Inland PM-22 is a monocore .22 LR suppressor built by Inland Manufacturing in Dayton, Ohio. At 7.5 inches long and 1.5 inches in diameter, the PM-22 delivers meaningful sound reduction on .22 LR rifles and pistols with a monocore baffle stack that disassembles for easy cleaning — an important feature for rimfire suppressor owners given the fouling .22 LR ammunition produces over time.

Why Monocore Matters for Rimfire
Rimfire ammunition — particularly .22 LR — is notoriously dirty compared to centerfire. The unburned powder and lead fouling accumulates in a suppressor’s baffles at a much higher rate than centerfire calibers, eventually degrading sound reduction performance if not cleaned. A monocore design solves this by using a single removable baffle element that unscrews from the suppressor body for cleaning, rather than multiple individual baffles that must each be removed separately. The PM-22’s monocore is the correct design choice for a rimfire-dedicated suppressor.
