Finnish Sneak, w/cheek piece

The cruddy photos are of a pretty rare 1970's target rifle made in Finland. Its a completely sterile M-39 that was put together under the noses of the Russians in the 1970's for officers target use. I've been shooting it for awhile and was getting a little tired of getting smacked in the nose by the scope, so I added a 1950's vintage M1-D cheek piece. I couldn't find anything else that would do the trick without messing up the gun. If any of you fellows know of a better mouse trap, I'd gladly like to here from you-SDH:D
