that last review....waaaaaaa if and i say IF someone was to go loco he would get hammered with paintballs AND dragonman would kick him out. and yea I would love to take a dive on cement oh boy. As for a shop....did you take a look in the back??? they have a huge shop and they are qualified to work on your gun. RMPP I took a tippmann in to the field shop nad they could not even figure out to take out all of the screws. so we can dispense with who can "work" on a gun and who can't. as for rental guns...open you eyes they have over 30 tippmanns. This field gets a Big 10 lots of fields big and small, cars, nice rest area, try it you will like it.
