Have one of the original huntmaster ar6 air rifles, need to know if anyone can lend advice on degassing, cant find anything, was going to loosen pressure gauge, any ideas other than that?
It’s threaded, just like any other gauge. There’s a white delrin disc in the hole that seals it . Make sure you don’t lose it . It takes about half a turn before you hear any air come out .
I believe Bagnal and Kirkwood have a parts diagram . It’s a UK based retailer.
