Got my new Optic in today, mounted it on a Larue LT 660 mount. has 12 settings:
0 is off
1-4 is for NV
5-12 is for normal use.
12 is so bright I don't think the Sun could wash it out. Going to sight this in Sunday.
Battery life is 50,000 hours on 1 2302 battery. After having a variety of fighting optics, from the reflex, tripower, eotech, and now this, this by far is my favorite. The weight is not noticeable, it probably weighs less than a combo of flip up sights.
