If you heard the controversy from a while back pertaining to the EOTech sight loosing/shifting zero under temperature extremes, you might be interested in watching my latest video where I explore that issue. Be sure to let me know your thoughts as well! Howard youtu.be/Q4N8l_sLtC8 |

Good Test, Howard.
Your EOTech has sure held a ZERO - and your dead-eye shootin' is well, dead-on!

Good video, Howard. I like the "real world" conditions of the test, even though it cost you in the amount of time that you had to spend. Thanks.

Howard, is this the kind of sight that our military uses in the field? I know nothing about red dots and optics. Thanks.  |

Another well done video. I will have to say that your test has proved to me that the EOTech sight is one excellent product.

Thanks guys! This was a test I wanted to do for several reasons. First, and foremost, the rifle in the video is the one I keep ready at hand while I’m at work. If, God forbid, we ever get an active threat call, that is the one I’ll grab as I’m responding to it. I built it specifically for that purpose. It is as light and fast handling as I could make it, and I wanted a sight that would allow very quick target acquisition; especially at close range. The EOTech fills that role nicely. Even though my rifle typically sits comfortably in my office, I wanted to KNOW it would hold its zero if it happened to be subjected to very hot or very cold temperatures.
Shortly after I built my rifle, stories started to circulate about the EOTechs loosing zero under extreme temperature variations. The first reports came from the military, and before long some Federal Law Enforcement agencies joined the chorus. Ostensibly the military tested their sights and found something like a 6 MOA shift at extreme hot and cold temperatures. There was reportedly a law suit filed against EOTech for “covering up” the defect in their sights. This all lead to some local agencies dumping their EOTechs even though they had served them well to that point. This was all a little too much for me to swallow. As a former Sniper and current long-range precision shooter, I am pretty well acquainted with the deviation to a bullet’s point of impact imparted by environmental factors. I also know, as mentioned above, that the temperature’s effect on ammunition is likely to exceed any variance attributable to the sight. In short, it is unrealistic to expect a rifle/sight/ammunition zeroed in North Carolina, at sea level, in 75 degree weather to shoot to the same point of aim in the mountains of Afghanistan in 110 degree weather.
I suspect a lot of decisions regarding the EOTech sights were made by people with little or no knowledge of interior or exterior ballistics. As is so often the case, once reports/rumors/tall tales start making their rounds, the piece of gear that is vilified becomes the excuse for any/every instance of poor performance (anybody remember the Winchester Silver Tips in the aftermath of the FBI shootout in Miami?). Again, I wanted to test the EOTech sight for myself, and I wanted to share the results. I hope maybe it will encourage others to test their own gear rather than relying on the stories/rumors told by others.
Howard
