What's the best scope for your eyes. Not my eyes; a buddies eyes; your eyes. Or better yet, what scope for less money will meet your needs.

I'd go to a big box store and test out the scopes available for sighting, with your eyes, on a darkened area, as many yards away as possible.

When I was young, I went one year with open sites. The next year a 4X scope. When older, went to a 3X9 scope. The higher power wasn't for shooting, it was for telling how many points the rack was.

For a Marlin 336 I'd look for a shorter scope.
