unless your real good with a drill press and tap Your more than likely going to have to see a gunsmith. I know around my area it is around $14 a hole for drill and tap which is not bad seeing this is a small job in the gunsmith world.
If it has a groved reciever
(two slots on either side of the top of the action) then you are just going to need a scope and a set of 22 rings. Midwayusa sells them as well as just about any sporting goods store. If you don't know what your looking for ask a guy for 22rings. They will know exactly what your looking for unless your in a Gander Mtn.
