I just bought one of the Primary Arms red dots for an AR15. I got the "advanced micro dot" sight. Battery is a 2032 and is supposed to be good for up to 50,000 hrs. when set about the middle of the brightness range. We'll see how long it lasts.
I have bought several Lucid red dots in the past. Three or four of the larger ones that look sort of like a trijicon and one of the smaller ones. The thing I liked about them was they used a common AAA battery. Now, I'm finding out they go dead (batteries) just sitting in the corner with the sight turned off. We've picked up two different ARs, that have been setting for 5 or 6 months without being shot, and the batteries were dead in both of them.
This time we'll try the PA sight for awhile before buying more.
