hey guys, I am still quite up in the air about what optic to use, although I have narrowed it down to either the Aimpoint ML3 or the M4. Now obviously the M4 costs more, but by the time you add in a quality mount for the ML3, it gets in the neighborhood, at least close enough to not rule out the M4 based strictly on price. So my question is, what exactly are the differences between the two that would sway me to one side or the other? I know battery type is one of the main differences, but is there any serious difference in the overall quality, dependability or type of electronics used? In regard to the battery type, I know a lot of people prefer the more common type found in the M4, but don't the batteries used by the ML3 technically have longer shelf life? In case of the good ole hypothetical SHTF/Zombie Apocalypse situation, is it better to have a shitload of long lasting batteries in storage that are good for 10 years or be able to find batteries practically anywhere (AA's)? I'm thinking that, in the SHTF situation, batteries will be among the first things that people snatch and grab, so those AA's might not be as easy to come by as people think, especially since they power so many different things. The ones used by the ML3 are primarily digital camera batteries, right? I doubt if many people will be concerned about taking pictures when they think the Four Horsemen are riding into town. Aside from battery concerns, what else should I think about to decide between the two?
