I bought an Akela a couple of weeks ago and since then I've fitted a Rob Lane reg. Very easy to do and the rifle now shoots properly. Yet to discover the shot count but I know it's going to be good and consistent.

As the manometer no longer shows air tube pressure, but regged pressure, I'd like a manometer with a scale more suitable. perhaps up to 150bar tops. These can be bought but with a choice of thread sizes. Anyone happen to hnow what that is? 1/8bsp, 10mm, but probably not NPT as the gauge didn't have a tapered thread as far as I could see.
