The best .22LR suppressor is without a doubt the Dead Air Mask HD. It's one of (if not THE) quietest .22LR can on the market, it's baffles are designed concentrically, so it's a precision suppressor, and it has zero first-round pop. It's also one of the most durable and toughest (rated up to .17 HMR and 5.7x28) .22 cans on the market being that the baffles and end caps are made of 17-4 stainless, and the tube is Grade 5 titanium. The baffles lock together to seal the leading and carbon building in the baffles, so it doesn't affect the outer tube, and the baffles won't ever get stuck in the tube to where you can't take it apart (foolproof). I've never had an issue with my Mask HD dropping crap back into the bore or into the action of my guns, but I also clean my suppressor every 350-500 rounds, so I don't let a lot of crap buildup in it that could potentially cause an issue. Regular .22LR suppressor maintenance is paramount, as .22LR ammo is nasty to shoot.
Also, the 17-4 baffles can be cleaned in an ultrasonic cleaner without damaging them. Do not put the tube or end caps in there, it will remove the cerakote finish.
The Dead Air Mask 22 HD is a 6.6-ounce, 5.1-inch user-serviceable rimfire suppressor constructed of titanium and stainless steel with impeccable performance.
