Sounds like similar issues I had with mine, and it was only on a 5.56. It was fine for plinking here and there, but failed on me at FrontSight. Same on/off issues, dot ghosted, etc. Back to the drawing board I guess. At least they have a great warranty.
I had an EOTech before too, but can't decide which route to go now. EOTech XPS+/-magnifier, ACOG+/- RMR, Accupoint+/-RMR, Aimpoint+/-magnifier...
