Moar EO Tech for Everyone!

I love the G.33, but their HWSs? After all their issues?

L3 Technologies, parent company of EOTECH, has confirmed they have been awarded a $26.3 million contract to supplied the latest version of their EOTECH holographic weapon sight and G33 magnifier to USSOCOM. The five-year indefinite delivery, indefinite quantity contract will see an unspecified number of optics and magnifiers manufactured at EOTECH’s plant in Ann Arbor, Michigan.

...

The selection mirrors a similar set up recently adopted by the German KSK, around the same time. Germany selected the EOTECH EXPS3-0 and G33 Magnifier for their new G95K (Heckler & Koch 416A7). Incidentally, this set up was tested by members of the Germany Army at the US Army’s Yuma Proving Ground in August 2018...

Is the new stuff actually trustworthy or... what?

I might say that's tinfoil, but the amount of BS I see in contract-related shit in my career is stunning (my favorite: long detailed evaluation of suitability among 6 big vendors; the demonstrably worst vendor is selected, six months later the guy who made the selection is a VP at the selected vendor).

Therefore, I am entirely cynical now, believe anything in this domain.

Eh, it’s $26M on an IDIQ.  That is a ceiling price.  It’s not like we pay them all $26M up front.

Shoobie, 

When was this?  That’s a clear ethics violation depending on the dollar value.

A Soldier without bullets is just a tourist!

Years ago. And not USG. The place had ethics issues. National newspaper articles on chief officers fucking up stuff. We got posters about it, and were told to tell our employees about ethical behavior. I told my folks that the sort of unethical behavior the company worried about was above their pay grade, so drive on and don't invest too much of your 401 (k) in company stock.

Nope...the issue isn’t solvable.  Their website even says so.... ridiculous. 

For example.... it was 65 yesterday here in my AO....this weekend teens..... for sure getting zero shift on an eotech.

 

we switched to aimpoint all the mechanical zero shift related issues magically went away.

Will the HWS hold zero as temperature changes?

  1. 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. For sights manufactured after October 2016, the typical shift will be between approximately 1.4 and 1.8 minutes of angle (“MOA”). Due to manufacturing variations, however, a particular sight has the potential to shift a maximum of approximately 3.5 MOA at -4°F and 122°F. Sights manufactured prior to October 2016 have the potential to shift approximately +/- 5 MOA at -40°F and 122°F.

    Due to thermal drift, sights 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.

    Shifts result 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 73˚ F then acclimated to 50˚ F, less shift occurs. On the other hand, if zeroed at 73˚ 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, 3.5 MOA is a shift of .875 inches at 25 yards, and is 3.5 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.

Ugh, I just reread that. I remember when it came out, and this part still makes me angry

1) Thanks for explaining angles to us all

2) Thinking 3.5 moa is NBD is so  

3) It's not us! Stuff happens. Strictly true, functionally bullshit. 

4) Sure, just ask the enemy if you all can re-zero before the fight because it's hotter than expected this afternoon.
