AGD Tac One Leak Down Barrel If Not Depressing Trigger

[coaram94]

Hey all — need some help again. AGD Tac One has a constant leak down the barrel UNLESS the slightest amount of trigger pull is engaged (and subsequently when I depress the trigger all the way down to fire, the leak ceases). I’m having a very hard time finding a good video on disassembling and maintenance of an X Valve. I’ve found the OG video on YouTube for a mag disassembly, but that valve seems to be slightly different than the X valve. That video does address leakage down the barrel when pulling the trigger or not, but I believe the parts/o-ring fix does not sync up with the X valve.

I’m sure this is an easy fix, but before I go nuclear and try to completely disassemble the X valve and introduce new problems, I’d like to solve the isolated one as it stands.

Also — I’m reading up a lot on “X valve rebuild kits” but everywhere I look they are sold out (and AGD’s site is down). Am I out of luck trying to get one of those, or are there still a few spots to find them?

Thanks in advance for helping me figure this out!

Does the leak stop if you press on the front of the bolt while aired up?

Do you have any shims in your LVL10?

There are 2 shims in there (not 100% certain that I’m talking about the level 10 shims though — are there any other shims in the entire valve assembly?).

I’ll try pressing on the front of the bolt when I troubleshoot again tonight.

For either case, what do you recommend for fixes?

Thanks!
