Ok so i have seen many people with the Stage 3 rail and they are running a mech. pressure gauge on the pressure test port on the right end of the rail. I am interested in doing the same but im not to familiar with what fitting i need and what size.
Here is the page i was looking at, could someone suggest what one i would need?
