ok, i got tired of using the "jury" so i decided to go out and buy an air tank. so i get to wal mart and i get a 7 gallon air tank for 15$ i stop at a gas station, fill it up, and go home, i get home, then it hits me. i was like hmmm if this tank is filled to 120 psi, i can only pump my gun to 120 psi...then when i get a few shots, the tank will be filled to like 80 psi, then i'll only be able to shoot at 80 psi, so i was like poop. So i called my buddy and he brought his little compressor over. My tank was at 40 psi, so we started filling it up, it took almost 10 minutes to fill it up to 100 psi. Ok, what kind of compressor am i going to have to buy to fill this thing up faster. Without spending 100$ i want something small and powerfull, and no cig lighter attachment.
