    Hi everyone, I am considering getting an Eotech for my AR, my brother had one on his but recently sold it to use irons, he said it was a great sight but wanted to get back to basics. This is actually his highroad account. I want to get one for my AR and wanted to know what the highroad community thinks of them, to get a second opinion from a good source. I found one on ebay and i think its a good deal for the price considering my brothers sold for 400 and the seller is near me.

    What do you think?

    I haven't used one all that much. It's neat technology and probably allows for more accurate shooting than an Aimpoint due to the crosshair reticle versus plain red dot. Some people don't like them because they run through battery much faster than an Aimpoint.

    Do you think the one in that ebay auction is a good deal? Im only in high school so money is hard to come by, I would have just bought my brothers whose account this is but i didnt have the money then.

    I like my 511, a lot.

    The only downside is, it runs down the batterys in storage unless you remove them.
    They stay in "standby" mode even when turned off.

    But that one you linked on Evilbay is too high, with too much risk, IMO.

    You need to Beware of Chinese counterfits on Evilbay!

    I'd suggest you check out Optics Planet for the best EoTech prices from a real EoTech dealer.

    Two basic problems with Eotechs:

    1) Battery life is way shorter than the Aimpoints. Think weeks instead of years.
    2) Eotehc sights fail. I've seen 2 Rev F units quit working while shooting. No warning or anything, the reticle just went away. Battery swap didn't recover either one, although leaving the batteries out for 2 hours did.
    If it's just a red dot you want to check out, try Primary Arms. I wouldn't recommend their sights for duty use but for plinking they are fine and have good customer service.

    There are so many counterfeit optics out right now I'd only buy from a third party if they are willing to give me the serial number so I can contact the manufacturer and see if it's legit.

    Those problems are in the past. Doing your own research of failure rates of post-Rev F EoTechs will convince you that L3 has fixed those past issues and that these optics are now extremely reliable.

    Love my EOTech! The battery life is poor compared to other sights, but AAs are cheap:)

    I like my eotech. There may be sights with longer lasting batteries or a little bit more durable, but for close and fast in my opinion, nothing beats it.

    HOWEVER.

    If you are strapped for cash, consider this: With irons, you can be almost as fast, especially with some training.

    I'm an eotech fan. I prefer the 516's because they use the same batteries as my flashlight(s).

    I try to keep all the batteries the same if possible.

    The 512 is a good sight, that price is good, but not the best I've seen. You can do better if you're willing to look around.

    Check out the classifieds on the various gun boards. Consider the 517 as well, which is like the 512, but with the buttons on the side (easier to use with a magnifier) and a 7mm riser/mount built in. Will allow for lower 1/3 iron sight co-witness.

    I have used all the different optics that the Army has to offer on the ar platform after many years as an Infantryman and multiple deployments to the sandbox. The eo tech is my preference. I can afford to put any optic on my personal rifle i want, and i have chosen eo tech multiple times, for multiple guns, and i would do so again in a heartbeat!

    The last one that i bought was a 512, and it was $373 (and yes NIB) from www.dsgarms.com with the mil discount.

    Aimpoint. Too many bad reports on Eotech on another forum from trainers who see lots and lots of 5.56 fired every weekend.

    I have two Aimpoints - one on my FAL, one on my AR. My DMR clone has a scope. Next Aimpoint purchase will be an H-1 for my lightweight.

    As BSW mentioned, the Primary Arms is a (so far) a decent inexpensive RDS - have one on my M&P-1522.

    My eotech has run just fine for about 2 years now. BUT I do run irons with it just in case. They co-witness, so its good to go.

    I have not had any issues so far. Its true the battery life is low compared to the others though. I just keep an extra one handy. It is a good idea to just change the batteries every couple months if its going to be a defense rifle.

    BTW I think bushnell makes one that is very similar that may be worth a look.

    Eotechs are a bit to fragile for my taste. Battery life, as stated, is also way to short.
    All that aside I would never buy anything gun related on Ebay. Half the stuff is broken and the other half are knockoffs.

    A new Eotech, yes. I like the 516, personally (like rjrivero said, it takes CR123 batteries, same as most weapons lights, and you can get them in the photo section at Walmart). Battery life on the 516 isn't too bad---1000-1100 hours at a pretty bright setting, more if you turn the brightness down---and it does a lower 1/3 cowitness right out of the box. The AA models have slightly shorter battery life with AA lithiums, and much shorter with AA alkalines, but on the other hand AA's are cheap.

    I really like the Eotech reticle compared to a simple dot, and the dot is as precise as an unmagnified red dot can get (it is smaller than the diffraction limit of the human eye). Sight it in at 50 yards and you are within a couple inches of the line of sight all the way out to 225+ yards, and someday if you keep an AR for defensive purposes, the bottom center of the ring provides an excellent aiming point at in-the-home distances.

    I'd be leery of a used Eotech because you don't know if it's one of the earlier, less reliable issues or if it's been abused.

    FWIW, the Eotech model numbers can be a bit confusing, so here's a rundown:

    Eotechs come in two basic flavors: (1) those that are set up for a lower-1/3 cowitness right out of the box, and (2) those that are set up for an absolute cowitness out of the box and need an aftermarket 7mm riser to do a lower-1/3. Within each of those two categories, some models have the capability to go ultra-dim for use with night vision equipment, and some don't (with NV capability jacking up the price quite a bit).

    The following models are set up for a lower-1/3 cowitness out of the box, thanks to a built-in 7mm riser: Eotech 516, 517, 553, 556, 557. As far as I know, all other models (including 512, XPS series, etc.) are set up for absolute cowitness, so if you want a lower 1/3 cowitness you'll need a 7mm riser, like a LaRue QD mount.

    Battery requirements are as follows:
    • 516: two CR123, 1000hr runtime at brightness 12 (longer at lower settings)
    • 517: two AA, 600hr runtime at brightness 12 with alkaline, 1000hr with lithium
    • 553 (similar to 516 but with NV setting and QD base): two CR123, 1100 hours runtime at brightness 12
    • 556 (similar to 516 but with NV setting): two CR123, 1100 hours runtime at brightness 12
    • 557 (similar to 517 but with NV setting and multi-dot reticle): two AA, 600hr runtime at brightness 12 with alkaline, 1000hr with lithium

    The XPS series all run off a single CR123 battery and are set up for absolute cowitness (they need a 7mm riser to do a lower 1/3). The designations are as follows:
    • XPS2-0 single dot in circle (traditional Eotech reticle), no NV setting
    • XPS2-1 single dot only (no circle), no NV setting
    • XPS2-2 two dots in circle, no NV setting
    • XPS3-0 single dot in circle (traditional Eotech reticle), NV setting
    • XPS3-1 single dot only (no circle), NV setting
    • XPS3-2 two dots in circle, NV setting

    FWIW, if you ever find yourself looking at Aimpoints, their model designations are a bit easier to understand. Basically, the CompM series has rubber armor and night vision settings; the CompC series is the same optic but without the armor and NV, making it much cheaper; and the Micro is a scaled-down model for light weight and small size (Micro T-1 has NV capability, Micro H-1 does not). You can get various models with 2 MOA, 3 MOA, and 4 MOA dots (I prefer as small as possible). All Aimpoints will need a riser to mount properly; LaRue Tactical makes some of the best Aimpoint mounts, but there are other players in the market as well.

    I love my EOTech on an AR and prefer it over a conventional RDS. They are not cheap however, and battery life is shorter than many RDS. Plenty of battery life for hunting and range use, but on the low side for "duty" use.

    I've heard of the durability issues, mostly from an instructor who hates them. I have not seen any issues other than with the early N battery models. Anyway, you need BUIS, even if you have the almighty Aimpoint - it isn't immune to rocks.

    Mostly agree. I would never buy anything electronic or anything from an individual or unknown seller. However, a few well-known dealers have accounts there and for some odd reason sell at better prices than they do on their own website. Case in point, the PWS FSC devices sold by Red's Trading Post on ebay.

    For the OP, a really good, high quality RDS for $150 is the Vortex Strikefire. If your budget is at all limited I would get that instead, with its much longer battery life and unlimited lifetime warranty.

    I've had both Eotec and Aipoint and perfer the Eotec by a mile regardless of the shorter battery life. The Eotech gives a much wider FOV.

    I am confused by this statement. What does field of view have to do with a RDS? When using an RDS, no matter why type, you should be shooting with both eyes open. The only interference with your FoV is the actual casing which is about the same on most RDS.

    I have a EO, 2 ACOG REFLEX sights and a 2x7 Leupold mounted on AR's. My favorite is the EO it might have something to do with the guns but I think more to the small 1 min dot. As far as batteries there is no doubt that the Relex sight are superior with the tritium and fiber optics and if I ever have to go to man hunting they may be my choice but even then as some combat tested shooters say they choose the EO.
    I just like the variable intensity and the small dot, when I take it out I just turn it on and leave it, if I buy another it will probably be the shorter mod. that takes the 3v bat. and has side controls.

    As a high schoolers on a budget (we've all been ther!), can I presume this is for fun mostly rather than duty?

    If so, I've had Great luck with some of the knock off products.

    Check out the PrimaryArms.com Aimpoint knock offs in particular. You get a lot of range time, the look and fun at a fraction of the cost.
