reg tester
just another idea, maybe if a suitable adapter would be found, the venting grubscrew hole could be used to fit a manometer to it. i take it that is post reg so it will give the true reading of the current reg setting
must be a tough little adapter/fitting, with a little gauge on it, the smaller the better. and not to be used very often/so you don’t mess up the threading.
this is not a tool to adjust the reg, but just to get a reading. 😀
is it M4 or M5?

ok I can confirm that I successfully measured my regulator output. purely with the manometer and the brass adapter. the air cylinder had to come out of the action. so quite a bit of fuxing involved hehehe
but it was cheap and I am happy to know what is it set to.

to adjust it, well it may need a few iterations, but all you need to measure its original length and turn it in or out by a known length. I hope it helps.
p.s. my gun has got a vent hole with the blanking grubscrew
