So I decided to try taking one of the FACOGs apart to see what's inside.

Playing around with the ocular lens reveals that if I can just move it 0.040" to the rear the reticle is in focus!

I'll bet that a shim or thicker gasket would do it.

Marv has argon to displace the humid air when we seal it back up too.
