How it's sighted in at the factory is a bit of a mystery to me.

I had one... liked it better than the Trijicon reflex sights. Got mine cheap, sold it this year. I would never pay full price for one, too many disadvantages to the relax design, too many better options without all the problems.

The thing I find with tritium is, it's hard to know how long ago the tritium was manufactured to the time a consumer purchases it. It could have been made and sitting on a shelf for three years or whatever till the time it's purchased and put of a rifle. The whole time the tritium is decaying. With a half life of 12 years( half the glow) you're losing valuable years. I also find the usable benefit of tritium is quite a bit less then 12 years. Maybe that's increased with the fiber optics but I have no exp with that combo. I find regular tritium sights are kaput after 7-8 years. Don't know how much these units are to Relamp.
