Old Paintball markers and equipment, make me an offer. I'm flexible and could go lower if you want the whole lot.
They are in great condition and have never failed me. Tippmann just don't seem to break.
Here's what I have:
Tippmann 68-Carbine with hopper, 14 oz tank, and J&J Ceramic Barrel upgrade, maybe? $60
Tippmann 98 Custom with hopper and 20 oz tank, also? $60
9 oz tank with stock butt plate $15
Assorted extra parts and cleaning items.
