Somewhat off topic, but on my AR15 I have a Vortex Spitfire 3x with an illuminated (red or green) prism scope with an etched range finding reticle. It works just like a normal scope when not illuminated.

This is a different tool for a different circumstance (longer range shooting) It can also be used both eyes open where it appears very similar to a red dot.

On this weapon I have replaced the gas block elevated sight with a short Pickatinny rail equipped gas block with a laserMax pistol laser on it.

There are no iron sights, but the laser and illuminated reticle do co-witness after a fashion. The Spitfire comes with a riser that allows co-witnesing with standard AR15 elevated sights but I chose to mount the scope without the riser to get the sight closer to the bore axis.
