This 20oz big tank is perfect for a few paintball games because of its
gas capacity. Tanks this size and up can get a little heavy after a
while but you can always put the tank in your tactical vest and connect
the gas to your marker via a Tippmann remote coil! You can expect to get
about 1100 shots per 20oz Ballistic tank depending on what marker
you’re using aswell as how high your velocity is
