Every time I decide I want an ACOG, I can never figure out which one I want. They come "close" to what I want, but never hit the mark. Then, I start thinking about the cost, and the "advantage" of no batteries. After further consideration, I consider the no batteries feature to be the primary reason I don't get one. The tritium has a half-life of 10 years, then it starts to fade. The reality for me is that whatever I would mount the ACOG to will get taken to the range less than 10 times in the next 10 years, and will sit in the safe until one of my kids gets it. By then, the tritium will be faded and at or close to the end of it's life. I know the military likes them because they don't have to worry about that stuff.
Personally, I'd much rather have a low power variable that I can just replace the battery or remove it altogether if I want to preserve the electronics. If you don't need the 6x, 8x, 10x, etc. then just leave it at the lowest setting and don't worry about it.
If you decide to consider the LPVO instead of an ACOG, there are a large amount of options to look at and decide from.
