You've already ordered the scope and now you ask about it? Try it and the let US know how it is.
But here lies the problem. You wrote of 4x scopes cause your Marlin came with one? Was it a good one? A bad one? How did you decide? What scope is it? etc Etc. Not all scopes are created equal and sounds like you could you use a lot more info than just that about the scope you already ordered.
For the record, I've never seen a Marlin .22lr that needed more than a good ol' 4x.
