Ive had my .22 pro sport since 1998 never touched it apart from a wipe down after ive used it. its one of the only air rifles I own that I can pick up and it shoots straight right from the first shoot somtimes I need to give the scope a couple of clicks but this can be after 4 mounths without shooting it so nothing but praise from me I hope airarms keep up the standard we dont need anyone eles going down the pan .good review by the way.
