I have a 3-9x40 on my AR. I like it a lot better than the illuminated reticle 3.5-10x50 Vari-XIII i have. I think the accupoint has better glass, and the illumination is much better. I like that it's always ready to go (no need to fool around with a rheostat, etc.) and i don't have to worry about batteries. Also, the "brightness" of the dot always seems to be perfect IMO, day or night.
