EOTECH Optics Issues

No sight is 100% perfect, period. Half the retards sending the sights back are making money off them. A guy at the local gun shop was bragging how he paid $350 for his and Eotech cut him a check for $550. Nice $200 profit.

No sight is perfect, sure, but in this case they were flat out lying about the specifications. And how exactly is making a $200 profit on it retarded? It won't get you rich quick, but it seems like a solid return on investment.
 
The reason i sent mine back was that i was planning on selling to re try aimpoint after having lasik to get rid of astigmatism and i got more money from the refund then i would ever have gotten on the ee form my 10 years old eotech. Now that i have given aimpoint another shot i made my decision to buy another eotech
 
Cowitness with Iron Sights, zero them together. When your eotech wanders you can tell by looking through your irons. Mine doesnt wander. Besides it talks about wandering zero in you zero in ambient. If you show up to the desert and zero it in 40 degrees Celsisus its not going to shift. Its when you zero in 40 degrees Celsisus and then take it to -40 degrees celsius. All Militaries everywhere zero their rifles to new environments anyway, you go to the Ghan you zero in the ghan, you go to the arctic, you zero in the arctic.

Yep.

I'm not saying I think the problem is OK, it should have been identified and fixed a long time ago if it had been found... however your logical reasoning is why I don't see why there is so much of a problem... especially for the bulk of Canadian civilians who probably are fine-weather shooters and never take their gun outside of a range... (If I was to hazard a guess, I would imagine that a good percentage of Eotechs in Canada are mounted on restricted firearms...)

I understand it to a greater degree for law enforcement, even if it is an unrealistically small likelihood that a rifle acclimated and zeroed at 40 degrees Celsius to be shot in a life or death scenario after sitting and acclimating to some of the coldest weather our planet can throw at us.... a difference of 80-100 degrees celcius... all without rechecking zero...? Seems like anybody that has legitimate fears of this happening might have seen too many action movies...

Anybody want to edja-macate me if I am wrong in my thinking here?

Do you know how hot it gets inside a trunk of a car in the summer? Or how cold it can get in the mountains of Afghanistan or at night.

Will the HWS hold zero as temperature changes?
EOTech’s sights experience a point of impact shift away from the point of aim when the sight is exposed to a temperature different from the temperature at which the sight was zeroed. After zeroing the sight at or near ambient temperature (73°F), the zero position will shift during operating temperature changes. The sight has the potential to shift approximately +/- 5 Minutes of Angle (“MOA”) at -40°F and 122°F. Due to thermal drift, the sight may not return to zero. The sights have the potential of approximately a +/- 2 MOA zero shift upon return to ambient (73°F) after being exposed to any temperature between -40°F and 122°F.

This shift results from natural thermal expansion or contraction that is present in various materials as they are heated or cooled, and is greater the more extreme the temperature change. For example, when a sight is zeroed at 70˚ F then acclimated to 50˚ F, less shift will occur. On the other hand, if zeroed at 70˚ F, then acclimated to 0˚ F, more shift occurs. The shift may not be significant to shooters who use their sights at close-quarters ranges. For instance, 5 MOA is a shift of 1.25 inches at 25 yards, and is 5 inches at 100 yards. It also is worth noting that thermal effects are evidenced to varying degrees in common optics, as well as in rifle barrels and ammunition as the environmental conditions change. In all events, to achieve optimum accuracy, the sight zero should be verified whenever the sight is exposed to marked temperature changes, and the sight should be re-zeroed as necessary.

Yup, they admit that now, but all the hate exists because they refused to acknowledge this for the longest time.

That said, I still rock my EoTech! Just love that Donut of Death on my Big TV Screen...

For people who shoot at the range its not an issue 99% of the time. But military people in the desert shooting day or night could be an issue. The fact that they lied and life/death is on the line makes me not want to support this company.
 
Despite the refund. I understand the concept of making money out of an old/used sight but...

Did you guys actually experienced issues with your sights?

Thanks guy. looking forward to hear about that.

P.S. I got a few eotechs on my firearms with the years and never had any of the describe problems.
