From what I hear it's a great reg, just as good as the Gladiator if not better. AKALMP makes it (they make the VLM cocker bodies and the excalibur) - www.akalmp.com. The output pressure is adjustable from 0-700 psi and the maximum input pressure is 800 psi. More info is at the website I directed you to.
I've noticed on the sidewinders that I've seen, they "ping" when you shoot them. I don't know if they all do it, but it drives me nuts!!! Some of the guys that had them didn't even notice it until I pointed it out, now it drives them nuts too!
