BRAND new Ninja Pro V2 SLP regulator, never fielded just had my tech put it on and test fire it to make sure everything worked. It's a Java 48/4500 carbon fiber tank, really high quality but it's 15 year lifespan is up in 8/17. It was hydroed in 2015 and passed. I paid $70 for the regulator and $200 for the tank and the regulator can of course be transferred from tank to tank. :)
