Bought one of these in good shape from the classifieds. If you've ever thought about getting an air rifle - do not get the spring powered kind. In my experience they take a lot of practice to shoot well, destroy scopes, and require a lot of tuning before they shoot well.

I can fill this thing with a pump and get about 20 shots before I need to refill it. No recoil and super accurate. It will shoot a .22 pellet at about 800 ft/sec. I took out 2 Eurasian doves this morning at about 30 yards. Out of the box, this gun is very loud and not backyard friendly. Mine came with a muzzle break that makes it almost completely silent.

Some day I hope to step up to a .25 Marauder, but that's a bit overkill for my backyard right now.
