    • Best sight to get right out the box.
Style: 512.A65
The EOTech 552 is considered the same model as the military version which includes the ability to see the reddot with night vison. This version, the EOTech 512 is considered the same as the military version, but without the night vision capabilities. A lot of folks will say that this fact alone makes this entire system worthless. Given that nighvision optics are rather expensive and impractical, at least in applications of civilian usage with the EOTech, this version is the ultimate one in terms of normal people wanting the same capabilities and power of the EOTech. I bought the 512 version and got it on my Bushmaster XM15. Overall I am very please with the sight system. I have since upgraded my BUIS to have a folding ARMS #41-b and the Matech rear sight. It's a very good combination and allows for clear picture without the front sight getting in the way. I mainly shoot 25 yards and 100 yards at the range. Overall the EOTech allows me to hit on target without much thought. You can keep both eyes open and have a clear picture of the target and unlike other options, you don't have to look at it dead on to acquire the target. The EOTech keeps on target and you don't have to look dead on. When others use the EOTech on mine, I notice they close one eye, try to align it and all that and be way off target. Not sure why people do this, but in all you don't have to be careful when you aim with the EOTech. The more relaxed and calm you are, the easier it is with the EOTech. When your battery dies, key thing is that the EOTech works very well with the BUIS of most weapons. You can easily flip up the BUIS, and aim really well without having to physically remove the EOTech from the gun. Zeroing the EOTech is super simple. However, it's rather hard to do with hands. You'll want a dime to adjust the sight. Once you do, you won't have to adjust it again unless you take it off the rails. I have the EOTech along with the G-33 zoomer to allow 3x magnification of the eotech. This is an excellent combination of medium range and long range. With the G33 you can zoom in, and keep it at 1x when you aim. There are really three negatives with the EOTech. One, it's very large, by itself that's okay on most rifles. However, that brings up the second issue that if you want to add a zoomer or any other accessories, you really lose a lot of real estate on your rails. The third problem is that you need batteries for it to operate. While that is okay given that most rifles these days have stocks and handguards that allow you to easily carry spare batteries. My overall thought is that you definitely don't want to run the EOTech without a BUIS in place in case the batteries run out. In all, I am very pleased with the EOTech. I can see why it was chosen by the military for usage on the field. My advice is that if you are not into long ranges, you'll want to get the EOTech. You can easily add a zoomer to get that long range in, but the only disadvantage is the space and weight. Otherwise you're going to have a blast with this and it'll last you a lifetime. ... show more

    • Adding sight to sighting
Style: 512.A65
Was skeptical about holo sights on my 5.56 AR-15 carbine, having been brought up on peep sights and some scope work. Leery of battery life. Easily installed this on my AR-15 top rail, and like the turn off/on buttons. No interference with the charging handle or other buttons, including a Magpul BAD lever. The reticle in the screen is bright, and brightness can be increased or decreased. My eyes had some difficulty putting the center dot on the front post (my eyes' focus), so obtained some dayglo white paint, and put a tiny dot on the rear-facing top 1/32" of the front post. It helped me a lot. Both target aimed and rapid (semi-auto) fire allowed me to use both eyes, and at 70 yds. my groups were 4" or less initially. Have gotten them down to 3" or less with about 10% centered bullseyes. Not bad for an old geezer like me, but I want to go to 100 yds. in my next session. Adjusting the sight was quite easy (well-marked knobs!), and in 2-click increments, took 12 shots (2 shots per segment) to zero in. Recoil (62g) didn't disturb the reticle, and windy dust didn't bother it either. The "coat" I got for it helps protect it and keep it clean in carry or storage. So I can recommend this slightly expensive item, and research indicates its type is battle-tested and rugged, as well as being a popular model. The price isn't bad: about the same as a good scope. But no telescope "wobble" when you fire. I still like peep-and-post shooting some of the time, but the holo sight is a useful aid to improving sighting and scores. Too early to tell about the battery life (two inexpensive AA batteries). So I'll keep the EOTech 512.A65. ... show more

    • Gold standard of reflex sights
Style: 512.A65
Since writing my initial review - I have taken this sight to the range 6+ times. I can actually shoot groups @ 50 yards (150 feet) where the holes in the paper are actually touching each other. I am not talking about just doing this once and a while - I am talking about actually shooting out the bulls-eye on my target. I swear to God, it feels like my rounds are guided to the target by a magnet! I haven't had to adjust my sight since I sighted it in the first time - I just instinctively shoot high (aim a tad higher than the target) when shooting at targets beyond 100 yards or more. I am very satisfied with this purchase: the HWS really is the gold standard when it comes to red dot sights. below is my initial review: it covers everything from my experience buying the cheap EOTech knockoffs to co-witnessing your sights (the right way) to the rail adapter on the HWS. Please read if you are considering purchasing the HWS because I present you with a lot of specifics about how to set this sight up the proper way. ******* I made the mistake of purchasing one of the mislabeled EOTech clones for my 6.8mm SPC M4A3 only to realize that the old adage, "you get what you pay for," applies specifically and directly to weapon sights. What this experience taught me is that I really like the EOTech design. You can't get a better sight for an AR-15/M-4 design than EOTech because these sights were specifically designed to work with that platform/firearm. The Chinese knockoff was a disaster - it couldn't stand up to recoil and had a cheap plastic battery compartment. I sent it back, grew a pair and bought the real deal (512 HWS). I couldn't be happier with my purchase. I paid $365 for mine, new, right out of the box. I took it to the range yesterday and the thing was already sighted in for my rifle (I had to make some fine adjustments for targets at the 100 meter range but I was impressed). The EOTech sights do come looking a little grainy compared to other reflex sights that use LED projectors. I called the company (just to make sure I didn't get a defective unit - very good customer service by the way) and they said the granular look of the reticule comes from the lasers in the sight. This was their (L3's) explanation: LED's are good BUT they are not as good (in terms of accuracy, durability and exactness) as lasers. Most cheaper units (like ATN, the EOTech knockoffs, AimShot and NcStar) use LED reflection to produce a sight picture - the trade off is that there is no compensation for the angle of reflection (producing an image that does not adjust or reflect evenly). This is why the red dots on those sights often look like an oval or have edges that look blurred and distorted. This is also why those red dot sights are notoriously difficult to sight in (and remain sighted in after several hundred rounds are put through your weapon). Aimpoint and L3 have corrected this problem by using lasers but the trade off is that this design is more expensive. A lot of people say the price difference is due to the little sticker on the side of these products - they don't know what they are talking about. Let them find out the hard way. If you are a serious shooter - L3 and Aimpoint should be the natural choices you gravitate towards. I've been involved in the sport (competitive shooting) since I was honorably discharged from the military. Over the course of that time, I've purchased Barsaka, Bushnell, ATN, EOTech Knockoffs and some other cheaper brands. If I had ponied up the money right from the jump - I would have actually saved money and time because I wouldn't have wasted the expense, rounds and time sighting in 6 other sights (all costing around $100). Co-witnessing your sight: Many people talk about co-witnessing their red dots with their Iron sights. This seems redundant and pointless. The entire point of a red dot sight was to reduce the amount of time it took to accurately sight-in on a target. If you are still using your Irons (both back and front in conjunction with a red dot in between), you take the same amount of time to sight in as if the red dot wasn't even there (because you are doing the exact same thing). True Co-witness with a red dot is using the front sight as a lower referent point (meaning the pin of the front sight) to center your red dot both horizontally and vertically. L3 built this sight with that exact purpose in mind. This sight is built 1.6 inches above the rail, which means you can still see the front sight in the sight picture but it appears exactly low enough to not obscure your target (you want to be able to see above and below your point of aim - this is the main problem with "irons"). This consideration is something most amateurs don't account for when they "Co-Witness" their weapons the wrong way. With EOTech sights, your front sight pin should line up with the "tick" at the 6 O'Clock position on the reticule circle. That's why I described your front sight's pin as a reference point, not as a point of aim. It's an easily (and quickly) referenced position to place your aiming reticule when shooting so you can instinctively shoot your zero every time. Another Consideration: Lastly and maybe most importantly, there is a huge difference between the rail adapter on my EOTech and that of the rest. The attachment profile (when you take it off and then put it back on) leaves a 1 MOA differential @ 100 yards. This means - at a 100 yard target - your error in point of aim will be 1 inch off your original sight in. On most of my other sights, due to defects in the design of the adapter, I had as much as 20 MOA in differential - meaning my shot was almost 2 feet off when I reattached my Baraska sight. Consequentially - cheaper sights mandated that they stay permanently attached to your weapon in order to remain accurate (and even when I did this - I would lose zero if I dropped my weapon or "nudged" the sight the wrong way). You really don't have to worry about this problem with L3 products or Aimpoint red dot sights - you can take them off and reattach them without losing zero (within 1 MOA differential). In conclusion: Look, I know this review has gone on forever. I am trying to help you avoid the mistakes I've made (and save you some green). These are considerations and conclusions I've come to after several years of experience with all different types of reflex/holo/red dot products. L3 designed their weapon sights to survive shock, explosions (within reason) and the tender loving care of combat. The ringing endorsement of the Special Operations community in the US military should seal the deal with all reasonable people because green berets and navy SEALs know how to put products, like a weapon sight, through it's paces. If these weapon sights are good enough for the Special Operations Community - they are good enough for anything I could possibly use them for. I hope you make the right choice.
