I have a Ninja olive dura tank with a Ninja pro reg for sale. It is in good condition. Has a couple small smudges on it on the label as you can see in the picture. Hardly noticeable. I currently have all the shims out so the output is around 450-500psi. I have the shims if you want them to make it high pressure again.
Asking $120 shipped and paypal'd. Thanks.
