"Used it in Iraq lasted my whole tour never had any problems. Got one on my own m 4 and works a charm. Only draw back is not great for long distance."

"I have been debating this buy for awhile. tried several of the low buck red dot units and they suck. This dude is the real deal. Easy as hell to put on and off, without readjustment and truly puts you on the enemy quick like. I had a hard time appreciating what I was getting till I got it. I can quickly target, in less than half the time as iron sights or a scope. It is very well built with the protection where it needs to be.I only wish two things, that I had spent the extra cash to get the Night vision friendly unit being that my next purchase idea is a quality night vision set up.The other quirk which is no big deal is that to turn it off, you have to push both buttons at once. To turn it on, just one button and the brightness is adjustable.It's just darn fun added to my AR platforms. works with A2 or A3 uppers and even works on my .223 pistol. I think it's good up to 50 cal bmg"

"I am about to embark on my second tour to the desert with this sight. It is an unbeleivable product. First off, every shot is EXACTLY where it needs to be. This sight is unbeleivably accurate. You'll never miss. The holographic bullseye makes this sight really good on the swing shot also, allowing you to shave a couple seconds of your initial shot burst. This sight is also very rugged. I have beat the S*** out of mine and it never fails to work. I have dropped it off the 2 story buildings (me with it) and off of my HMMWV and it always holds up and never loses it's zero. I have taken it off my weapon and put it back on several times and the zero is still always right on. The unique thing with this sight is that it has a cage like outer shield that protects the actual sight aperature. Does an unbeleivable job protecting it. The only thing wtong with mine is a few deep dings in the housing and a little lopsidedness also, but is still shooting at exact zero. The battery life is also amazing. Used the same batteries my entire first tour. This sight alsoi has many features that make it extremely handy, many different brightness levels, a setting for NOD's, the outer housing, long battery life, easy zeroing (just two controls that will turn with a screwdriver, leatherman, or even a simple knife), and best of all unbeleivable durabilkity. I would recomend this EOTech Holographic Sight to anyone looking for a sight that is accurate and will last them a lifetime, if not longer."

"Great for fast target aquisition. 1 MOA dot is good for precise shooting, if you are familar with your weapon/bullets trajectory you CAN use this out beyond 300m (accurately). Basically, a little \"holdover\" and your good to go longer range. Batteries last a very, very long time with this unit, AA batts are the best choice as they are the most common type out there. Don't forget some back up iron sights(BUIS)... just in case your batts fail or the Eotech \"breaks\", you NEVER want to be without iron sights on a weapon. Armor \"rollcage\" on the Eotech is tough. CTD also has some BUIS."

"I purchased the EO Tech 512 sight for my Bushmaster, and found it to be very effective. I am able to put all rounds within the target near the X-ring. I have been able to cowitness the red dot with my iron sights to make accurate shots. While I am not military or law enforcement, I do have the option of using the EO Tech with my rifle for defense if the need arises. Purchase an EO Tech 512...you won't be sorry!!"

"My agency recently adopted M4 carbines with the EOTech sight system. After zeroing the sight to the rifle, any other person can pick up the rifle and use the sight, still correctly zeroed. Unlike iron sights which are zeroed to the shooter, this sight is zeroed to the weapon. It makes target acquisition faster, as well as remaining accurate throughout.I highly recommend this product, used in conjunction with a quality back up iron sight (BUIS) such as those produced by GG&G."

"It took me a while to talk myself into buying this but I'm glad I did. I'm not a cop and am no longer active duty military so do I NEED this? No. Is it cool to have? Yes. It cost more than some of my guns but I now definately believe it is worth it. Splurge and enjoy."

"I first saw the EO-TECH 512 at a gun show... I have to tell you that this purchase was the best thing I could have ever added... This thing is on the money at all times. I really suggest this for anyone in LE or just into target practicing.... Very easy to install on my SIG 556.... I give it two thumbs up all the way!!!!"

"This sight is amazing for close quarter combat and long distance shooting! The red dot is only 1-moa. Which means it only covers one inch of your target at a hundred yards and two inches of your target at two hundred yards and so on. So at six hundred yard this red dot, only covers six inches of your target! That is amazing for accurate long distance shooting. Just use the whole sight for close quarter combat and get on your target super fast! And just use the red dot in the center for your long distance shots! You get the best of both worlds with this sight. I can shoot off hand with my M-4 at two hundred yards and hit a 10\"x10\" target with thirty rounds. I will take this sight over an aim-point any day."

"It took me a while to convince myself that $399 for a circle with a dot in it was worth the investment, but I am satisfied. I built an AR-15 \"Katrina Rifle\", zeroed the holosight to the iron sights and am now able to quickly aquire and hit eight inch targets at 50-100-150 & once in a while 200 meters. If you need one that is compatible with night vision, save your money and get this one. Just set the sight to its lowest setting and it works fine. I've tried it. The only differenc is that it takes a few seconds longer."

"Bought this sight for my Stag arms AR because I was tired of using cheap reflex sights that dont hold zero. I even had one that broke before I ever got it mounted on my gun. Dont waste your money on any of the cheaper sights because you WILL be disapointed. This sight is one of the best investments you can make as far as optics go. This thing is solid as a rock. I even dropped mine (by accident of course) from about chest high onto a concrete floor. The fall didnt phase this sight, not even a scratch. I mounted it back on my gun and it kept its zero just like I had never taken it off the rail...try that with any other optics and see what happens. Your gun is only as good as your sight system, so why chance it with a cheaply made sight?"

"This is a true point and shoot optic. Once you get it zero'ed (mine is at 25 yards) Just put the circle or dot on your target and know that you will hit. Make no mistake, this is not a scope. It is only as good as far as you can see clearly. My next purchase is the 3x magnifier."

"This is one outstanding optic! Rugged, accurate, uses either \"AA\" batteries (so easy to find) for around 600 hours of use or \"AA\" lithiums for about 900 hours (Though you don't get the low-power warning with lithiums that you do with regular double-As.), auto shut-down after a few hours, adjustable for any ambient light level, small enough dot size to make moderate-distance shooting possible--a really great sight. Just be sure to buy one of GG&G's flip-up covers for it. The thing is like Butler's caps, mounting absolutely securely between the inner housing and the outer roll cage. When closed, it completely seals the windows from accumulating any dust, spray paint (If you've been there, you know what I mean.), or getting possible scratches. When flipped open, the front cover opens to a horizontal position that makes a sun shade over the front of the 512, a nice bonus."

"This is a fantastic sight. It impressed both myself (beginner) and my father (experienced). Only took a few rounds to get it zeroed in properly and is very easy to adjust. I bought a scope to use with it, but even without it, this sight is pretty darn accurate for me at 100 yards (haven't gotten to try it out any further yet). Worth the money? Only if you want to hit the target."

"I decided not to waste my time with the other red-dot sights. Spending $$$$ dollars for a sight was a bit intimidating but as I've been told, \"you're gun's only as good as your sight.\"And in a survival/life or death situation I want the confidence.I was convinced it was worth the money after playing the video game \"COD4: Modern Warfare\" on my XBOX. There's no better way to test drive this sight! I have it installed on my M&P15 and couldn't be happier. My only concern is that it requires batteries. Keep your battle sights installed for back-up!"

"I am 69 years old (young?) I have two of these sights, one for a CX4 Beretta 9mm Carbine and one for an AR-15 Carbine. These sights are SO effective that I hit targets now faster and more accurately than EVER before. At 25-40 yards you should be able to have 6 tin cans rolling at once."

"Do not waist your money on all the cheap red dots out there! If your looking for a red dot that works, look no more these work just like they say and have more eye relief than the aimpoint stuff but those work very well too but I would rather have a open view for targeting zombies!"

"It is well worth the price. I talked to a lot of Marines out of Iraq. Most told me they didn\uFFFDt care for the ACOG and they ordered these with their own money. This is great for fast accurate target acquisition. This is the only red dot sight you will ever need to own."

Do yourself a favor and pass on the cheap red dots and spend the extra money on this, you won't be disappointed.

"Although I've shot with a red dot sight on a Ruger Mark II, this is my first holographic sight for a rifle. I had a little trouble adjusting to the sight due to having used optical sights 3x and larger. As an eyeglass wearer with progressive lenses, I had to adjust to seeing the nice small dot with ring. I could shoot and not worry about the dot being in exact center parallax. This was no longer a factor. The sight acqisition was fast. I don't have to worry once the sight is attached to the rail and sighted in. It stays where you put it and doesn't react to recoil or need re-adjustment. A great buy, great quality, and a dependable sight. I co-witnessed with a BUIS, but I likely will not need it due to the extended battery life. (I keep a couple of extra alkaline batteries in a waterproof plastic bag in my back pack, just in case)."

"I recieved my EOTech 512 two days ago and i am very impressed. I had wanted to purchase one of these since the day i bought my bushmaster. I was turned off by the price but i am happy i finally bought this sight. The quality is amazing and you def. get what you pay for. The sight was very easy to sight in and took me only 6 rounds to get the sight zeroed in at 50 yards. So far it has held zero after 500 rounds.I chose this sight for quick targeting and being able to keep both eyes open and can shoot a 3 inch group at 100 yards standing with rapid shots. Overall i would reccomend this sight to anyone, dont let the price scare you away."

"I had been contemplating this purchase in excess of 5 months to be honest, I had a Bushnell Holo-sight with a 1 m.o.a dot and T-reticle and I thought that was nice...resembling an A.C.O.G. also didn't hurt my feelings either. I can honestly say now, after a 8 hour day on the range and a few hundred rounds down-range, why did I waste the money on that Bushnell first, for the price. It is a nice optic, but by comparison, there is no comparison... out-right. This thing kicks as$, simply put, 50 yards, punches sight-in diamonds out in no time, 100 yards, 9, 10 and x are no real challenge. Highly impressed and would easily and emphatically recommend this sight to anyone willing to man up and spend the money on a quality sight. Installed on a Stag-Arms M-4 Flat-top lefty and couldn't be happier."

"The sight is awesome as everyone says. The only thing for me is that I ended up buying an EOTech 4x magnifier. This model works fine with the magnifier, but EOTech makes the 517 model for better compatibility with the magnifier. The issue is that the 512 sits a bit lower than the magnifier on the rail, but it does not interfere with functionality as far as I can tell so far. However, the 517 is raised 17mm so as to line up exactly with it. It also has the buttons on the side so the magnifier won't block them. I use the flip to side mount so I can still get to the buttons. So, all I can say is that this sight is sweet, but if you are going to mount a magnifier too, it may be best to spend 20 extra bucks and go with the 517. The 512 works for me though and if you do get the magnifier to use with it, you won't have a problem anyway."

"I bought this a few years ago for my AR-15 build and was pleased with it...at first. It works and is durable; it still works fine after over a thousand rounds through the rifle. My only gripe is that it eats batteries. This model uses AA batteries and I am having to change out dead ones every couple of months. Overall, when it has fresh batteries it works great and is a very accurate sight but it goes through batteries way too fast compared to just about any other \"red dot\" sight on the market."

"This is by far one of the best holographic sights that I have ever purchased. I put it on my Stag Arms AR-15 model 1, and it has done well for the 2 years that I have used it. For those of you on the fence with this all I got to say is that you will not be disappointed in this sight. Some of the concerns that I had with it were that it might not be high enough to look over the fixed front sight post. I installed it in a matter of seconds and the sight is high enough to see over it. This is handy if you are planning to install a flip up rear sight. I have dropped my rifle several times and have had the sight bang off the ground and it still holds zero. Hopefully my review helped you."

I checked here for this scope and wow, I was blown away by the cheaper price. When I received it, it was so easy to mount, and very easy to adjust for correction. Now I am loving this scope on top my AR-15. Got 5 shots within 1.5 inches!!! Now that's shooting."

"I choose the 512 becuase of the AA batteries. Standing at 25 yards I had a grouping the size of a baseball. At 50 yards the size of a grape fruit. Well built and stays true. Was $100 cheaper on CTD then my local store. EoTech is a great product and has a great following. If you're wanting a red dot sight aim for one of these. They're worth it. Will take up the whole rail on your AR-15 receiver."

The image being projected was \"fuzzy.\" Note in the product description that CTD isn't the contact for bad gear; all RMAs go through EOTech. I've been calling them for close to a week know and can't get any one to ever call me back. I just keep getting voice mail box after voice mail box.

"I bought this for my BFG-50, but it cannot be zeroed in. The manufacturer blames my rifle for having too high of a picatinny rail.

Look for some other sight if you have a high rail on your rifle."
