Fx M3 Leak after Side mount gauge install

***** Update******* it turned out to be the o-ring behind the second regulator and it would bleed some air no matter what out of the atmospheric pressure hole until you open up the second regular past a certain point. Not really sure how that o-ring blew from just removing the bottle and draining the pressure but it was a real pain to get to and have to reset the pressure there.





Hey hoping someone could tell me what I did wrong my M3 leaks from the secound regulator hole on the side of the rifle after installing the angled gauge now air drains from my bottle there and doesnt pressurize the rest of the rifle. I have tried everything I could think of to fix it so any help wouold be great

Do you have all of the proper o-rings installed on the under side of that angled bracket? There should be three of them - one very small one oring and another slightly larger oring plus a third x-ring at the bottom of the opening where the gauge screws in. If those are all there, make sure you tighten the two top m4 bolts down all the way (I know that sounds obvious but they need to be tight).

Yes I did it exactly like the videos but for some reason air is leaking from that hole I circled the Atmospheric hone it seems as something is blocking air from going past that point and charging the plentum
