Hmmm, you might have been better off with the pellet gun.
You need a measuring tool, internal micrometer or a good dial or digital caliper to see what the present bore is. If you ask the question I'd guess you don't have one or know how to use it. Before you can measure it you have to clean it up, ideally lightly hone or sand the bore to see if it is damaged. If there is much rust at all, it is damaged so whatever size you have, you will need the next oversize. Sleeving is an expensive operation. Price of the sleeve and then $50-$100 to put it in. A $50 shop will likely get it crooked, and not match the window to the port. New cylinders are cheap these days so you are often better to by a new cylinder than sleeving.

inside micrometer is a royal pain
telescoping gauge is better, than use with a digital caliper.
you cant use a caliper and measure the lip. it wont be right
send it to KOR. he will set it right for ya
