You might ... want to take a look at the: A O Sight Systems, Lever Scope mount & The Leupold M8 (2 1/2) Scout Scope combo.

This stuff's specifically designed for Marlin & Winchester lever-guns.

When used with a set of Weaver 'low rings', the result is very compact; the Leupold intermediate eye-relief scope is only 10" in length and adds very little weight to the rifle- and does not adversly affect the handling or the looks of your fine lever action rifle.
