If you have ever looked through an EoTech then you will know they’re amazing. This sight displays a reticle (a circle with notches at 12, 3, 6, and 9 o’clock and a dot in the middle) that can only be seen looking in one direction it also moves independently on the glass. A ruff explanation at best but this review is primarily to describe quality. This sight is super fun for distances as far as your naked eye can see, and if you throw a magnifier behind it you can easily shoot at longer distances. As of now the durability of this sight is amazing, I have had no problems with it not working when I need it (outside of batteries). I also have an AimPoint M3 and for the money the EoTech seems to be a better deal. The only thing AimPoint has that this doesn’t have is the rubberized sleeve (to prevent scratches) and lens covers. The lens cover is the only real plus to me though, I’ve read some reviews on the aftermarket EoTech lens covers and they seem to be behind AimPoint on that front. Despite that, this sight is still amazing. Though it may seem expensive to those who have never looked through or owned one by my standards it’s definitely worth the money for a cool and great functioning setup. Additionally I would say that after many ruff outings and hours of use my sight still looks and functions like new.

This is my first higher-end red dot sight so I really can't compare it to any others but I can say for the price I am very satisfied with the quality and utility. I have it mounted on an M&P 15 Sport and used the included knurled thumb bolt to make it easier to move to other weapons. Sighting in was very simple as it was almost dead-on from 50 yards right out of the box. A few windage adjustments and I was hollowing out bulls-eyes. It is a little bulky and seems like it could take a beating. I like the fact that it uses AA batteries which are cheap and easy to find. The reticle is bright and very sharp. I really like the 1 MOA dot for accuracy and the 65 MOA ring is great to help get on target quickly. The only negative I can think of is the lack of any kind of cover for such a pricey optic. I know a lot of the cheaper ones even come with a little sleeve. I did purchase a ScopeCoat for under $20 and it fits perfectly.

This is the second EOTECH optic I have owned. Also have the EOTECH MPO II which is the EXPS 3-4 optic with G23 3x magnifier. The EOTECH 512 is incredibly accurate and allows for rapid target acquisition. May use with a magnifier if you so choose. Just make sure you get a flip to side mount if you run in combination with this optic. The AA battery operation is a plus...you don't need to special order batteries when they go bad. And they are cheaper. My only gripe is the switches. They are at the rear of the sight instead of the side. Sure you can buy a different model at an added price, but in my opinion this should be a standard feature. In addition, if you don't have a ton of rail space this optic is rather long. However, it remains light weight because the battery case is composite, not aluminum or steel. Would still highly recommend this product. Unbeatable quality and no extra mounts required like the Aimpoint products. Great price. Have since returned mine for the EOTECH HWS II...only because I prefer the look of the shorter optic. If you don't need a magnifier buy this optic, you won't be disappointed!

I just received my scope today, and being a red blooded American, I immediately mounted it and shot a hundred or so rounds off. This thing was surprisingly accurate. Maybe my expectations for HWS are set low (I've had other red dot sights that are just "okay"), but this thing is scary accurate. At 25 years, I was shooting two inch groups from the bench. Shoulder fired, these became six inch groups. This thing is solid, and allows a true read on the target. I only had to adjust it two clicks to the right once I took it out of the box, and this thing is spot on. Well worth the money, I've had three scopes on my AR-15 which I didn't like, including a really decent hunting scope, but this is the best all around solution for accuracy, target acquisition and weight. One thing - not related to the product, is that I couldn't spend the 5-6 hundred on the EOTech magnifier, so I went with a cheaper, L&M Tactical magnifier. While that product leaves a lot to be desired, it still shot good groups with a cheap, Chinese magnifier - which I think is a testament to the trueness and accuracy of this product. I would recommend these to anyone with an AR considering a light, versatile and accurate (not at 200 yds, but in the 25-75 yard range) optic solution.

I just received this EOTech 512 a few days ago and have now had some time to form a better overall feel for it. The scope absolutely oozes quality, even though it's the bottom of the line. For some reason, I went with mounting it using the 7/64" allen screw instead of the knurled knob. I went to the range and sighted it in and discovered that it co-witnessed perfectly with the iron sights, or the other way around. Now, a day later and I realize that I'm not likely to always have the allen key with me to verify that the screw is snug, and EO cautions against using Loc-Tite, I knew I had to change screws. I took a look at where it was on the rail, took the allen out and inserted the knob screw. Back to the range to do a full sight-in again. As a very pleasant surprise, the first three-round group was all within the one-inch bullseye! When they say the alignment is repeatable, they mean it. As to the versatility of the optic: I took my friend and his eleven year old son to their property today to do some shooting. The boy, with no prior training and just about 30 seconds of instruction, was shooting incredibly well right out of the gate. The thing practically lines the gun up on its own. I don't think anything I could say would be too high a praise for this optic device. I've had several others and none can compare to this one. If you're looking for something in this line, all I can say it, "Buy it!" I don't see how you could be disappointed.
