The best size scope to get for a Crosman 1077 is defiantly 4X32, As the scope is in perfect proportion with the 1077, But a 4X40 would be just as good as well.
Here are a few images of mine, Note that I'm using a Simmonds 4X32 8 point scope!! (Sorry about the link instead of an image as the image service isn't working for me for some reason!?!)
