My mag setup:
- LV 10 (no shims)
- x-valve
- ULT (4 shims, pin is 0.75")
- Stock powerfeed body custom welded to vertical feed
- classic rail
- Powerlyte Powerstix frame
- Trigger rod about a credit card thickness from trigger back
I had problems with massive leakage and it was solved with help of many AO members. (Thanks guys! )
But after I test fired 100 or so shot the mag started to double fire - once on trigger pull and once on release. The only things I have done were the valve work to stop the leaks in this post. The sear is not worn up (it was working before) and the bolt lip looked okay.
Could the valve rebuilt have something to do with this? Or perhaps I need to change the o-rings in the ULT as well (or rebuilt)?
Thanks!
EDIT: I've inspected the ULT and all the o-rings are intact, the pin is 0.75" as spec and it has 4 shims.
EDIT: Resolved (see reply #11). It turns out the shims were a mix of ULT and LV 10's - replaced with all ULT shims and it's running smoothly.
X-valve parts list so we can discuss using part numbers:
