Yep, these are airsoft ONLY venues. Going to play paintball is incredibly difficult since there are very few fields and I can only think of one place I've EVER seen sell paintball gear. That said, we had two paintballers (speedball players) play airsoft with us this last weekend. I damn near got lippy to one of them since it SEEMED like "bounces dont count" with those two.... grrr...
Guns CAN have metal bodies now but the fps limits remain the same - max at 93 meters/sec using .2's.
