One clippard tank isn't enough, you don't have enough volume to move the piston fast enough. Try using as many as you can get, but plumbed in parallel, not in series, such that the greatest volume of air can move. Here pressure is secondary to volume.

If this isn't clear, I can explain further.

no, i am NOT using a piston. i hooked up the tank to a valve which sends all the air to the barrel through a push in connector.

ok, i will try to get some more parts to get the second tank to be in parallel with the first one. i think i know how i can do this.
