Need to know fast if I have a major issue. Just traded a guy and I have a little time to trade back if there is a problem.

Upon receiving it, the EO 512 rev F would turn off when I mounted it. (Would be on, then shut off when I torqued it down properly)


Decided the battery might be the problem. Installed new batteries and it seemed to work perfectly.

Then I head to the range and hour ago. I will admit all I have on hand are new, but bullshit cheap bulk batteries.

At the range it went dim from the recoil on my first shot, but then was perfect after that. Then I take a break to go to my truck to get something, after I return to the gun it has gone dim again. Not off, but at lowest setting probably.


Would premium batteries solve this? Is this  a real problem? Eject?

Mine would do that when the batts are running low.  It could also be a problem with the unit.  I would put some new Energizer Litium and try it again.  If the same problem occurs....RETURN IT

My first thought is that it isn't working right.

My second thought is to check to see if its real.

Ok how do I check if its real? I checked the obvious (no button in middle, no reticle change)

Open the batt compartment and take a pic of the contacts....as well as the glass, rear, side (L & R), top, bottom and front.

We can tell...

I would give it back unless you got one hell of a deal, it might be something as simple as needing to clean the battery contacts or as complex and needing to be thrown in the garbage.

Ok doing that now

I love eotechs but the battery cases and contact points are weak and in my opinion a fairly poor design.

I have one case that is almost brand new (no corrosion, no loose springs or rubber shock pads) which won't deliver more than 1.2v with fresh batteries. So clearly a shitty connection somwhere on a VERY simple circuit.

Solution: I took a bare piece of 16 gauge copper wire and bent it into a shape like O-O and dropped it into the bottom of the battery compartment (the part which is towards the front of the rifle) so that the wire sat on the little foam pads and spring contacts. Then I set my batteris on top and it now delivered the full 3v.
Then I clamped it shut on the optic.

It was a tight fit but this solved the problem.

So far from the pictures that you posted especially the one from the bottom, that unit is authentic.

I see you have the GG&G covers over the lenses.Was the whole top of the housing replaced with one from GG&G? if so Eotech will not warranty it if the cover has been changed.

I think this is an internet myth, has EoTech stated this somewhere?

Call EoTech.  They helped with a problem we had on a 512.  It sounds like someone may have put in the wrong batteries in yours and fried the board.  $65 will get it fixed for ya.

The unit looks like a real Eotech.  It is almost certainly the battery contacts.  That is the weakest link for this optic.  I have had 5 Eo's and only one had BC issues.   It was a 512.   I sent it back, and got fantastic CS.  They fixed it and sent it back in 7 days, and they did not charge me because all it needed was a drop in replacement contact.

It still works to this day....about 4 years old now.

I only run Energizer lithium batteries in mine.  They are much lighter and do not shift around, thus possibly damaging the contacts.

I agree. If it turned off when you torqued it down, something is probably twisting or shifting out of the way from the battery terminals...

I have four, two of them have been back for repair and one is dimmer than the rest and needs to go back.  It's so bad that in full daylight the sight washes out.  I just haven't' gotten around to doing it yet as I have a spare.  

Customer service from them has always been top notch.
