Good to see you back here at Treeological. Today I want to talk about gun sights. The company known as Electro-Optics Technology (and abbreviated as EOTech) was founded in 1995, after it broke off from its parent company. It is an outfit which designs and distributes electro-optic products. Its headquarters are in Ann Arbor, Michigan, and it has a client base of civilians, military organizations, and government agencies all over the world.
One of its most popular products is the EOTech holographic weapon sight (HWS) model 512. Of all their sights, it is this one which is the most widely used (in the category of non-night-vision-compatible models, anyway).
The HWS 512 is meant for use during close to mid-range battles. It is a non-magnifying optic, so it is not useful at longer ranges. But, it does provide a shooter with fast target acquisition, and that is what counts.
The sight has a red ringed and dotted reticle. For close targets, use the ring. For longer range targets, use the dot (1 minute of angle [MOA]). Whether you use the dot or ring, the reticle will not move. The shooter has complete control that way, and is able to shoot with both eyes open. In other words, you can find your target and even transition between ranges, without losing your focus or compromising your situational awareness.

As far as price is concerned, EOTech’s 512 is one of the cheaper models, which also contributes to its popularity. You can find it for around $400 at shops and online stores. EOTech’s line of HWSs is easy to use, and very friendly. It is a breeze to maintain and clean. Once you zero in your 512, you won’t need to keep fiddling with it. It holds zero quite well, and is sure to serve you and your weapon for a long time, as long as you treat it right.
The front and rear windows provide an image which is clear and true. There is a 2-year warranty on materials and workmanship, and EOTech will repair or replace its products, if deemed necessary. Most of EOTech’s products are made right here in the U.S., and that includes the entire HWS line.
The HWS 512, by EOTech, is still one of the most popular sights out there. Recently, EOTech got into some hot legal water, but the lawsuit was settled out of court. These days, EOTech is trying to rebuild its status and its trust. It should have no problem doing that, I think. Mistakes happen, but EOTech produce quality items very consistently.
