Things I liked: Low cost and easy to setup
Things I would have changed: Perhaps a light sensitivity adjustment for indoor use.
What others should know: I had to put two spotlights above it to use it indoors. I have a 10yd indoor range so I do most of the chrony testing indoors. It still doesn't work on every shot. I might need to do some adjusting of the illumination.
Things I liked: Very well built. Mine is 25 cal. Many people complain about the trigger, but it seems fine to me. For under $300 you can have fun, powerful 25 cal air rifle that does not need any source of air.
Things I would have changed: I found it difficult to get this air rifle to produce tight, consistent groups. I'm told one has to find the right pellets. I don't know if this is something Crosman can improve on. Perhaps it's too much to expect for an air rifle under $300.
