Things I liked:Solid built gun with an EXCELLENT trigger. Things I would have changed:Rear sight was loose and fell off after about 500 rounds. My fault really for not realizing it sooner. Put sight back together and, wonder of wonders, the zero doesn't change now. If I were to change anything it would be to make the sights out of metal. Plastic is ok, but.... What others should know:This is an adult air rifle!! It' weighs a lot. Not for smaller kids. Accuracy is very good once you find the right pellet for your gun. Mine likes the Crosman Destroyers best. highly recommend the 10-for-10 service.
