My old Marlin 336 st. grip carbine has a 3X Leupold in QD Talley mounts and it looks fine to me..I think the Marlins are nice with a scope as they were designed for scope use, so take advantage of it..You may need to shoot a doe in the head or a turkey, that scope would be handy for that.

I would never scope my Winchesters as they are not designed for scope use and I really like iron sights anyway..

These guns are ment to be used up to 200 yards and I don't need a scope for 200 yards and under.

Bottom line is the option is yours, do what you want to do, why ask?
