Greetings Arkansas Fan,
I sat down with the President, new VP of Ops, and the Director of sales for Federal/Mil of EOTech last month for a briefing on the reported issues, status of product improvement and quality control, and the state of the company. As expected, the new leadership staff was forthcoming in their descriptions of their own shortfalls and quality control measures. The VP of OPS described the company wide changes that have completely transformed the way that EOTech does business, focusing on quality control measures implemented that begin at the vendor level for the parts that EOTech purchases to build their optics. The discussion included the reported issues (cold WX distortion, reticle fade due to moisture incursion, parallax, and thermal drift), the causes, and the changes implemented to fix said issues.
Long story longer, barring a personal distaste for how EOTech previously conducted business, IMO you will not be disappointed with their products. The reported issues occurred at extreme temperature ranges under some fairly arduous conditions...and did not affect all of their optics. The new EOTech seems to have fixed their Sh!+.
I have been issued and used EOTechs for more than a decade and have never had an issue. I currently use an Aimpoint Micro T1 at work solely due to replacement of EOTechs due to serviceability. Our stuff gets beat up. For reference, I have a Trijicon ACOG on my personal rifle. I have also used Aimpoint Comp M2 and M4s as well as the older Trijicon Reflex sights on work guns.
Here are my personal thoughts on these optics. All are excellent depending upon what you are using them for (CQC, target shooting, home defense, medium range, etc), how you are using them (feed it often and keep it serviceable or armory clean after every outing at the local sporting gun club), and shooter preference ( "I like the way ______ looks better").
I wish you luck with your choice. Always remember...if you aren't happy with it, I know a few folks who will gladly take it off of your hands for a "used" price!
If anyone is interested in the non NDA part of the EOTech briefing that I sat in for, PM me and I will be happy to send it.
