Guys, you may want to dump your EOTech sights.... linkLooks like the sight may not hold zero in extreme hot or cold, as well as it not being adequately sealed against humidity. Suit in Federal court by Uncle Sam VS L-3 and EOTech for not disclosing this defect even though the company knew about it since 2006. |

I did not see if it was one specific model or all models of there sights. Since it says back to 2006 i will assume it affected the older models like 511 and 512 . It also has the part where the FBI did some test in 2015 where it found the EoTechs it had were faulty. Did they test brand new versions or the old models it had is stock?
I do not have enough information as to what models ( like the ones i own) are affected to trash can them. But this will make resale prices drop no one wants to buy a broken sight.

From what I understand, the thermal drift issues only crop up at the far ends of the temperature spectrum so on that end many folks may be just fine as long as their AO doesn't hit those temps. The humidity problem (infiltrating the casing and causing problems with the electronics) seems more problematic to me from a prepping standpoint. All in all, if the issue isn't likely to effect yo in your AO then you may very soon have the opportunity to pick up some Holosights very cheaply. If it is likely to effect you, dump 'em now while you have the chance  |

I havent read all of the reports, but it seems the issue is a matter of several MOA of drift. In very extreme temps. Since that is still probably better than the amount of drift I personally would cause in temp extremes, I am not that worried.
I need to read up more on the humidity problems, though.

My friend bought a new eotech, can't recall what model, a few years ago. He's a typical hobby shooter who only goes to the range once every two months or so and is putting at the most 200 rds down range. He had the fogging issue. Also had another friend many years ago with the battery issue. Regardless of the thermal drift problem happening at extreme temps, fuck those guys for endangering MIL and LEO lives. Glad I've been an aimpoint fanboy from the start.

I need to read up more on the humidity problems, though. Same here. I have a 10 year old one that uses those funky "N-type" batteries, a 512, and a couple of XPS models. It gets pretty hot & humid around here, but so far I haven't noticed any MOA shifts or fogging problems when shooting in our muggy summers. |

I might elaborate further if I have time, but I've had zero issues with my xps's which I have used heavily as a civilian shooter. My marines that opted to use eotechs never reported any issues, either (I believe we had the old 512s). Obviously quantity over quality can always have an effect, but I'm not ready to throw them under the bus.

Obviously quantity over quality can always have an effect, but I'm not ready to throw them under the bus. If you have ones that have performed well and reliably for you through thick and thin then I wouldn't see a reason to ditch them. The temperature extremes issue is pretty much a non-starter as a concern for most civ shooters, and rightly so. It's the humidity issue that would concern me as a civ, and that seems to be a design flaw that rears it's ugly head on a case by case basis; ie it's not easy to predict. For the record; I've had an EOTech. I absolutely LOVED it when shooting. LOVED IT. It just ate batteries like candy when compared to an AImpoint (I still don't own an Aimpoint) when left on in storage. I'm not bashing EOtechs by any stretch. |

I have two 512's and I don't think I'll be dumping them...its just more something to keep in the back of your head if the weather's real cold. For instance there have been threads like this splattered all over the net for awhile.... www.ar15.com/archive/topic.html?b=3&f=18&t=609452...where cold weather will either stop EOTech from working period or where users will report a shift in POI in cold weather. Always noticed those threads here and there, but never really thought to much about it. Sort of paying a little more attention to them now, did a couple searches as a result of that article and I'm reading them. On the POI shift I've been noticing in the posts that most of the months that these are posted in are in December and January. I live in TX though, not Michigan or Montana so it doesn't get super cold here and plus the only times I really shoot when it's really cold in winter is when hog or deer hunting (and usually I'm using a scoped rifle). Would probably never have bought a new EOTech again anyway, but this somewhat seals the deal. Will just shift gradually towards Aimpoint or maybe check out that Trijicon MRO. I kinda think that's more the middle ground rather than hurriedly dumping them. They aren't any worse than they were 6 months ago when Aimpoints and EOTechs were ' the optics used by Tier 1 units' and Primary Arms and Vortex were barely capable of mere range use.  (meaning that the EOTech's I had still worked back then). |

I decided to return my 511 and 512 for refund. I had to estimate the purchase price, since both sights were more than 6 or 7 years old. I decided on $325 for the 511 and $425 for the 512. I filled out the online form on the EOTech site, and within 2 days (I filled it out on a weekend) had recieved an email reply showing a return authorization for both sights. Shipped both sights (I shipped them separately) on January 12 and they were recieved in Ann Arbor on the 14th. Now, we wait to see how long it takes a check to get here. Per the reply I recieved, I will get a refund of the purchase price plus $15 shipping (I presume for each sight).
So far so good. The online forms were easy to fill out and the refund was promptly agreed to. We'll see how things shake out, I'll keep you all updated.

My 512's been solid, outside of eating batteries like a hippo at a buffet. Never had any fog issues and the coldest I've had it out shooting was -15F; from what I could tell it held zero.
That said, my next one will be Triji or Aimpoint. I'm tired of buying funky batteries and having them chewed down in a weekend.

That said, my next one will be Triji or Aimpoint. I'm tired of buying funky batteries and having them chewed down in a weekend. Batteries were somewhat of an issue, and to my knowledge neither of my sights every had the thermal drift, but the more I thought about the whole mess the madder I got. I mostly sent them in on principle, not because of any issue I've uncovered. My 511 was mostly for funsies, but the 512? It was supposed to sit on my wife's patrol rifle, bumping around in the trunk of her squad car, waiting patiently through 0 degree weather and 140 degrees of humid horror (I never actually stuck a thermometer in the trunk while the car baked in the middle of a parking lot, but you can imagine...), and the promise EOTech made was that if the worst day of her life happened and her getting home safe to me (or a bunch of panicked citizens getting home safe to their loved ones) was dependant on her ability to put a bullet into a bad guy, that sight would do it's job if she did. Well, as far as I can tell, L3 continued to knowingly crank out a product that demonstrated serious potential for accuracy issues (I've read as much as 10 MOA of permanent drift in some sights). So fuck 'em. Products that don't live up to their promise get sent back with extreme prejudice. |

Actually thought about sending my EOTech's in for a refund for quite awhile after those posts in November, what finally did it was actually that I got a wild hair to get something new and something had to go.
Only issue I ever had with mine was the short battery life.
At any rate I received my check today...yea!!!
So it's actually not a scam (where they just took my EOTech, threw up deuces and told me to get bent and then sold it at a discount rate along with thousands of others to the Saudi military to use in Yemen or something).
Was going to get a Trijicon MRO or an Aimpoint of some flavor, however I'm probably gonna use the money for another 2 day pistol class instead though.
Skill/training trumps gear....yada yada.

Received my ' Yeah, you're approved and you can send it back to us' email on Dec 23rd and I shipped it that same day. Heard nothing back from them when they recieved the package in the first week of January, so a I sent them an email on January 13th confirming that they'd gotten it and I got a generic email back on Jan 15th saying that it was all being processed. Left it alone and kinda semi-forgot about it til now. If you sent yours around the same time hopefully it shouldn't be too much longer. |
