I recently ordered an EoTech 512 holographic weapon sight from Lincoln Tactical for my Stag Model 2T AR15. I was looking for a non-magnified red dot optic for my carbine when I found out about EoTech a couple of years ago.
I was impressed with the build quality of this sight. If it waterproof for up to 33 feet, fog proof and was designed to withstand mil-spec drop tests and still operate. It has a corrosion resistant finish and should withstand any physical abuse you put it through.
Even though I wanted to get an EoTech, I spent some time shooting my carbine with just the iron sights. As I wrote in a previous post (found here https://sheepdogtheory.wordpress.com/2011/05/09/backup-iron-sights/) I think it is important to become proficient with your backup sights before mounting an optic.
This sight is incredibly easy to use. It mounts to any mil-spec picatinny rail using the supplied allen wrench. The sight takes two AA batteries and is easy to turn on with the touch of a button. It has several brightness settings which are nice as you can see the reticle in both bright and night conditions. It will automatically turn itself off after a period of time to save battery life.
There are a tremendous amount of options out there when it comes to optics and backup iron sights and I wanted to set up my rifle to have the sights co-witness. Co-witnessing is when both the iron sights and the optic line up in the same plane. This allows either sighting system to be used without having to remove the optic. As you can see in this picture, to use my backup sights, all I have to do is raise them. I do not have to remove the EoTech to use them. Most of the time, I will leave my rear sight down, but if I ever have to use my rifle and the EoTech has dead batteries or is somehow damaged, all I have to do is flip up the rear site and I am back in the fight. Other setups I have seen using ACOGs or Aimpoints require removal of the optic to use the backup sights. I don’t have to do that with this set up.
Using this sight has been great. It is very easy to use your peripheral vision with this sight and I am impressed by the size of the window this sight uses. This results in really fast engagement of multiple targets. I can’t express in words how fun it is to shoot with this sight.
If you are looking for an optic that co-witnesses with iron sights and doesn’t have magnification, get yourself an EoTech 512. You won’t be sorry.
