I'm in the panhandle of Nebraska. Getting compressed air is tough. Heck even getting someone to fill co2 is hard around here. I play almost exclusively with 12grams. When I played with it years ago, it had been in storage and it hadn't leaked then, I'm guessing it's fine now. As for nicks and scratches I think there's one on the front, but that's about it. I'll give it the once over when I get home this afternoon and see if I can't take some more pics. I just never get anywhere to use it, and another of my son's wants a pump so I'm trying to trade it.
