What is everyones recommendation for a scope for my .22. ITs a mossburg 42, pictured below. The scope is held on from the side (my uncle did it) and the scope he put on it is pretty crappy. I mainly do 40yd cans and 50yd targets, so something for that would be good. Also, not to expensive, so please post prices, or if you have one for sale let me know. thanks.
