Have the earlier version of the Marlin 60 that I purchased back in the mid 60s for squirrel hunting and plinking. Put a 3-8x32 (yep, 8 power) Bushnell Banner scope on it back then and it is still on the rifle. I'm not recommending the brand I have, just the power range, which I found to be useful. So, perhaps a 2-7 variable power scope would suite your needs.
