Yes. As I understand it the M5 was developed at the request of groups who operate OCONUS where 2032 batteries aren't common.

The M5 uses existing T1 format mounts so that's a win. It also has a reinforced front lens that makes the optic more resistant to severe impact. That's a win. AAA batteries are cheap and Aimpoint is still saying you get the 5 year lifespan. Another win.

I would prefer some type of "S" version too but can easily live with the 2:00 battery if the optic lives up to the claims.
