The only negative to using a screw-on suppressor, aside from its expense, is that it typically makes your firearm more cumbersome. Not so with SRT Arms’ integrally suppressed Ruger 10/22 ($1,195; $755 with customer-supplied gun; srtarms.com). SRT’s Doug Melton first tunes Ruger’s vaunted semiauto rimfire action to function with subsonic loads, and then he mates it to an internally suppressed barrel and a sound-deadening Hogue overmolded stock. With subsonic rounds, it’s the perfect tool for snuffing squirrels, rabbits, and pesky noise complaints.
