Nice rifle! A little Leupold 1.5-4X20 is a good fit on my old Marlin .35 Rem. I really appreciate a good LPVO on my AR but it’s hard to beat a lightweight 1” tube on a lever gun.
By modern standards Marlin Lever guns aren't really light. Every scoped bolt rifle I own weighs less than an un-scoped Marlin 30-30 and only a touch heavier than an un-scoped Winchester 94. With that in mind you need to think about the weight of any scope and mounts you buy. It's easy to add another 2 lbs to the package.
