The choices in .22LR are pretty wide open. The Tactical Innovations suppressors are really good for the money. They have the Tac 65, Quest and Stratus. We've sold a number of them and customers are very happy. I've got a Tac 65 with about 10K rounds through it and no issues whatever. Take-apart cans for easier cleaning...important in a dirty .22 LR. http://www.tacticalinc.com/22lr-models-c-21_24.html?osCsid=d6efvuikg62ijvcvmbj3a3rm36
GemTech makes some .22LR stuff thats great quality, Silencerco makes the sparrow with a neat shield to insure that you can get it apart to clean.....Lots of other manufacturers out there.
