Aimpoint PRO's are great. I used to run a T1 but got rid of it for a 1-4x on my sbr. Changed that to my 308AR and went back to a red dot on my sbr again. Didn't want to spend the money for an Aimpoint again so I opted for the primary arms micro dot with 50k+ battery life. So far it has worked great pretty much exactly same as the T1 idk if I'd take it to war but for what I use it for it works great and at a quarter of the price as the Aimpoint and it has the 50k+ hours and night vision capability that the T1 had.
