I'm an eye doctor. I'm curious to what happened to your eye and what sort of treatment you've done for it. Feel free to PM if you don't want to disclose openly.
Gonna be hard to find a individual willing to sell a decent 22 can or any suppressor for that matter. You can form 1 a suppressor also. With a bunch of the kits out there these days you shouldn't have trouble finding one that is your skill level.
