I picked up a tank with what appears to be a generic reg for one of my kids guns - it was set to 800PSI. I'd like to dial it down for his new Mini GS - I know - it has an internal reg and does not care what you put on it, but I've never seen this no name reg and well..... if I can i will, curiosity killed the cat. what am i dealing with here? do i just take washer out and see what it does to lower pressure? don't touch it?
