First, these are about 1/3 the price of an aimpoint. Unless your life depends on your equipment or you have to have name brand tacticool stuff on your AR. I would go with this vortex. The caps on my first one were pretty hard to close, but much easier on the newest one(Press them in the center if you have trouble). These red/green dots are an outstanding value and a great low light sight.
Pros: Holds zero, comes with mount and caps, night vision mode is useful at night without NVD
