I live in the suburbs and would like to take up some backyard plinking and pest control (House Sparrows, Starlings, and Squirrels). I am wondering if any of you airgun vets would be able to make some suggestions for an air rifle that could fulfill such a role. I'm not willing to spend more than $150 for the gun, but would like to have the option of getting a scope to aid my old eyes if need be. Thanks for the help.
