The Gemtech GM-22 .22 LR suppressor in black is a lightweight 7075 aluminum rimfire can (Gemtech part no. 12127). Gemtech rates it for .22 LR, .17 HMR and .22 WMR, and its G-Core design is a one-piece monocore baffle stack that is easy to take apart and maintain. At 5 inches long and 2.7 ounces it adds almost nothing to a rimfire rifle or pistol. A preventative lead buildup coating helps keep the baffles cleaner, which addresses the usual maintenance headache with rimfire cans. It is a straightforward, multi-purpose choice for a threaded .22.
