RT Valve and X-Valve velocity inconsistency issues

[ghost flanker]

I think I finally figured it out. It seems my inconsistency issues between the four guns in question were actually a combination of any or all of the following culprits;
- Reg springs were super dry in all four guns (probably main culprit). Greased springs with Dow 33.
- A bad reg valve pin assembly in at least one gun. Replaced.
- Slightly bent ULT shim in one gun causing varying degrees of short stroking as well as a delayed bolt reset. Replaced.
- Level 10 bolt weld spot possibly rubbing ID of Docs adapter in one gun. Dremeled bulge on L10 bolt for a flush surface.
- Reg seats. Replaced in all guns just for good measure.

The X-valve in my main gun had all 5 of these issues. It’s been a while since I’ve been this frustrated with an automag, but now it’s shooting with a velocity spread of roughly +/- 8 FPS.

Glad you were able to finesse it back into a normal range! Thanks for sharing your solutions.
