I found these guys on line. This is the most sound reduction currently available in 22 can. they dont have a picture of it online and it is a relatively new suppressor from AAC. but they go from $400 up everywhere else. Cant beat the price. I called to make sure everything was as advertised. check um out if you want one. Read up on these too super quiet.
