I bough this scope mount years ago before I bought a Marlin XT-22 bolt gun but then I never ended up buying the Marlin so I've had this unused for a while.
This is the mount in question so see here if it will fit your gun

I live in Seattle, work in Tukwila, shoot mostly in Bellevue so I'll meet anywhere around there. I also go to USPSA matches in Renton and Paul Bunyan ranges often so if you're willing to wait for a match we can meetup there too.
