Tried to sell this one for a friend a while back, close to new condition, had test test Co2 Cart in it still, I was a little suprised no one wanted one.
It was indeed a heck of a nice repeater as was the Crosman 400 (I liked that one even better as it was 100% wood & metal-the 622 had a plastic clip).
Fun factor, bring back the 600! It would be out of my price range but has to be tons more fun that whatever simi auot plastic is out there selling for $300ish.
All time favorite, Crosman 101 !
