RE: marlin lever action scope mounts?
I have this set up on my Marlin Guide gun. Some advantages like quicker target aquisition, easier to shoot both eyes open. Disadvatnages are numerous. Low light sucks. Light behind you will obstruct view. And my least favorite is the field of view. Very limited up close.
However with all that said I like mine but my Marlin is going to be a walking gun and not a blind gun.
