Things I liked: Love it. It was easy to install and sight-in. My eyesight is getting worse making accuracy all but impossible. I had never used one before and didn't know what to expect, but this scope did help. Nothing but head shots on those pesky squirrels now.
Things I would have changed: Nothing
Things I liked: Uses the same clips my Crossman C31 uses.
Things I would have changed: Not very accurate nor powerful when I compare it to the C31. The handle hangs when sliding it to open or close. Difficult to tighten the screw for the CO2 cartridge. Will not fire the H&N Sport BBs I purchased to use with it. Magazines frequently doesn't engage properly and as a result, frequently no BB is loaded.
What others should know: If I didn't already had a the C31 to compare it with, I might have a better opinion of this gun. That being said, I would probably not recommend this gun.
