Thinking about getting a refill kit for your paintball CO2 tank? Maybe you've got a scuba tank and you want to transfer some air to a smaller tank to feed your paintball gun. We've got portable refill kits for the 'on the go' field refill or air transfer from a master tank in your garage.  Perhaps you just need some more O-rings for your high pressure air tank or a cap for the top; you're in the right place!  If you don't see it here, email us at: questions@choicepaintballguns.com.
