Okay so I am not a huge fan of the holographic sight but you never know, I may change my mind one day. I am a newbie after all! 

I learned a little about them and it is interesting, especially the construction complexity verses a reflex sight.

A holographic sight, also known as a holographic weapon sight or holographic diffraction sight, is a type of firearm sight that projects a reticle, or aiming point, onto a small glass window in front of the shooter's eye. The reticle is typically in the shape of a dot or a crosshair, and it can be used to aim the firearm more accurately at a target.

Holographic sights work by using a laser to project the reticle onto the glass window. The reticle is created by the interference pattern of two lasers, one of which is reflected off a holographic grating and the other of which is reflected off a mirror. This creates a three-dimensional image of the reticle that appears to be floating in front of the shooter's eye.

Holographic sights are popular with shooters because they offer several advantages over traditional iron sights. They are faster to acquire a target with, as the reticle is always in the shooter's field of view, and they are more accurate at longer ranges. They are also more durable than iron sights, as they do not rely on mechanical parts that can break or become misaligned.

Holographic sights are commonly used on rifles and shotguns, but they can also be found on handguns, crossbows, and other types of firearms. They are typically mounted on the top rail of the firearm, allowing the shooter to co-witness the reticle with the iron sights if desired.
