Tac,
My 338MXLR has an express sight on it and at 25 yards with the factory front sight it was hitting 4" high with LeverEvolution ammo. I haven't built a front for mine yet, (trying to get all my customers front sights made first) but I'm predicting needing about a .450" tall front.
I didn't shoot it with the factory rear sight so there is no reference to work from there.
The sight picture is amazing however and accuracy was one ragged hole. (only 25 yards though)
Hope that helps!
