Congrats, love the old Marlins. Consider buying a scope that has a 32mm objective instead of the 40mm, lever action rifles don't have a raised comb and anything over 32mm will have you lifting your face off the stock to see through the scope. Also stick with low rings to keep the scope as close to the barrel as possible. I've got 3 of these rifles; one has a Bushnell Elite 2-7x32mm, one has a Bushnell Banner 1.5-4.5x32mm, and the other has a Nikon P223 3x32mm fixed power scope. All three of my scopes can see deer beyond 200 yards during legal shooting hours. Anything larger just adds unnecessary weight and bulk to a rifle that is meant to be a quick handling carbine. If I had to go buy a new scope today, I'd buy another Bushnell Banner 1.5-4.5x32mm. This scope is simply the best value out there, the lens' are clear and bright and there's more than enough magnification to hit a deer as far out as the 30-30 can reach. Don't be surprised if your gun doesn't like the 160 grain LE ammunition, a lot of the older guns just shoot better with the 170 grain flat or round nose bullets. Each one of my Marlins has their preference, but they all shoot Federal blue box 170's really well.
