    So what are you using instead of Eotech?
    (e.g. Aimpoint Comp M4S, Elcan SpecterOS3.4x )

    The latest Eotech's they're talking about 1 to 5MOA.
    The Aimpoint Comp M4S advertises as 2MOA, Aimpoint Micro H-1 as 4 MOA.
    Have a look over here eotechlawsuit.com. They have all the information regarding the failures and the court documents from the US Gov vs L3/EOTech lawsuit. The shift that Eotech admits to in your link is what they want you to focus on, which they admit to as between 2-6 MOA, not five. What they don't want to talk about is how the sight is not sealed from the elements and reticle fade or failure is common. They also don't want you to know about the failure to return to zero after the optic has experienced "thermal drift" can be as much as 2 MOA. Nor do they want you to know that the parallax error can be as much as 4 MOA, and that has nothing to do with temps. That is all about head position and reticle position within the viewing screen. So Add that up, 6 moa for "thermal drift", another 2 MOA for failure to return to zero, plus the possibility of a 4 MOA parallax error from reticle position. I come up with a worst case scenario of 12 MOA, and that's if the reticle hasn't faded or disappeared.

    By all means, let me drop $800 for a sight that doesn't work as advertised with known defects dating back to 2006. The answer is Aimpoint and has been for decades. Parallax is an issue with all optics, but EOTech marketed theirs as "parallax free" which is a lie. I'm sure you'll see POI shift with other reddot type optics, but thus far none have proven to be as bad as EOTech.

    I haven't heard of reticle fading problems, at least none not related to battery life or extreme sunlight.

    Several people still swear by their Eotechs, for non-professional use.

    The 6MOA error seemed to be for the older models, whereas the 5MOA seemed to be Eotech's position on their models manufactured after 2014.

    There's this from elsewhere:

    It affects all the sights, including the latest ones. There does not appear to be a fix for the issues at this time, and given that the issues are a result of the technology, unless there is a major advance in holographic laser technology, or L3/Eotech change to a different technology, there is unlikely to be a fix.

    It is also a mistaken belief that it only occurs at temperature extremes, as shifts of 2 to 6 MOA due to thermal drift can occur within the given temperature range, and paralax error up to 12 MOA at 0C and 20 MOA at -15C can occur.

    What does it mean for someone who only takes their gun to the range? You may have to re-zero it whenever you go to the range. If you hunt with the sight, it could result in a missed shot, or a wounded animal.

    Whether you can live with that is up to you. You currently have the option to return the sight to the manufacturer for a full refund plus $15 shipping.

    Some people are returning their sights, because they have experienced issues, some because they no longer work, some because they can get more for the sight than they paid for it, some because they want to try something different, and some because they believe that the company committed an inexcusable act by knowingly selling faulty sights to people who put their lives on the line for their country and fellow citizens.

    Just because you haven't seen the issues listed above does not mean they aren't happening. Anyone foolish enough to keep a high dollar optic that DOES NOT WORK as indicated my the MANUFACTURER is fair game for open mockery. EOTech/L3 is offering a full refund to everyone with one of their POS products. You'd have to be a fool not to cash in and start again with a clean slate and a full wallet.

    Dig around online and have a look at the goat roping show that has been going on for nearly 8 months now. EOTech's largest distributor told them to get stuffed late last year as they apparently had not had communications form EOTech since April of 2015. LE departments are wising up and dumping them by the truck load. EOTech apparently is receiving two plus USPS truckloads per day of returns. The EOTech lawsuit site is very clear in describing the issues and what EOTech knew about for nearly a decade but failed to disclose or fix. Selling optics to LE and MIL who's lives are at stake while knowing your optics do not perform as advertised is some shallow sh*t. I for one will never buy another EOTech product on that fact alone.

    Are there any optics that don't (actually) have these issues under such extreme temperatures?

    Supposedly the new EO has solved all of this. The only legacy issue is that it's still in the 600 hour range for batteries compared to 2k+ for most of the others. That said it has the biggest and brightest dot on the market so you have to pick your trade off.

    Non-holographic optics for one.

    So basically anyone purchasing a holographic optic can expect this behavior?
