Just now saw this post had to read thru
As of June 2016 Eotechs were still the only red dots for SF guys. I say that because June 2016 my team time ended and I retired last October (2016).
I still talk to the guys on my old team as of right now they still have EOTechs.
If there is something other than Aimpoints coming? I do not know But if so chances are it will take awhile to outfit all of SF /SOCOM.
Just how long...Here is a example, the RISII (front sight post version) rail although adopted round 2009 I did not see one for every SF guy until 2014!
Any new gear usually goes to teams up for combat rotations first, rest of everyone else waits inline.
EOTech issues; I have seen a ton everything from the battery connector debacle around 2008 that effected a lot of them, to dots going off for no reason.
Even the coating coming off the lens in bad weather. Now ... I would say 75% of the time no issues.
And as far as the whole temperature zero shift issue. Really not a issue for SF since during a 6 month deployment to the middle east, Unless you zeroed in the summer and
stayed thru winter without zeroing its a non-issue.
Guys still use them because: That's all they know and have for red dots. And if they have a bad one usually just swap it out for a working one.
And really I would say for real combat OPS most guys run Elcans anyways.
FYI We had both Eotechs and Aimpoint Comp M4s around 2010 but SOCOM decided we only needed one red dot Optic. And turned in the Aimpoints.
So here we are 2017 looking for a new CQB optic.
