My 13yr old son saved up his money and bought a paintball gun. We also bought a 20oz Co2 tank which is a pain in the ass to get filled around here. The paintball range where he does battle has an HPA compressor and offers free refills to HPA users.
We need to look at buying an HPA tank for his gun now and I have no idea what we are doing when it comes to paintball guns. Can anyone give me some links to where I can find a good deal on some of these HPA tanks.
