Tippmanns are pretty much invincible. I used to play with a Model 98 and it's been full of sand, mud, paint, little rocks, whatever happens to get jammed in it while playing woodsball and scenarios. Once I ran it over with my car to see if it would survive, and it just picked up a couple scratches. No problems at all. They are as solid a gun as I've ever seen. Every other gun in its price range feels like a cheap plastic toy compared to it. Plus, they're made the good ol' USA unlike all the other guns in its price range.
