Had to shoot our qual course on my city issued carbine today, and the primary optic(Eotech ) took a big crap on me. I've been using this on the carbine for awhile, been through 2 carbine courses with it and have had no issues. Today, about 15 rds into the qualification course the recticle went bye bye..turned it back on, fired a few more, crapped out again. This happened about 5 times. The batteries are new. I later opened the battery box, cleaned the contacts, and re assembled. Seemed to run fine , beat on it a bit, turned on and off a few times, seems ok. Part of our shooting course involves a little running. I ran from the 100 yd line to the 25, and prepared to engage the target..guess what, sight crapped out again. At this point, I flipped up my back up irons and finished the course . Well, after that, I popped mr. Eotech off and replaced it with my personal Aimpoint T1. This isnt the first Eo to crash in our unit. Pretty annoying.

That sucks. Which model of EOTech? At least it happened in practice rather than when you needed it.

 

[diving dave]

Its the AA battery version with the Night vision capability..I think it the 552? I know of another officer who had same issue, related to springs compressing in the battery box. I suspect this one will be going back to the factory.

There is a little fix that may help out. Take out those little springs in the battery box and carefully stretch them out/pull them apart. That should help out a little bit until you get them fixed.

MIght try that.But the end of the battery compartment ,where the contacts are, looks like the rubber piece there is glued on though...Since it belongs to the city I might not mess with it. Hope I dont start one of those"Eo vs. Aimpoint" threads, but I have a ML2 and a micro T1..Both have run without a problem.

That rubber piece and the springs come out. I disassembled ours plenty of times.

Eotech had a link on their site about returning a model for failed contacts. I remember finding it by googling it after an Aimpoint nut friend of mine was trying to stoke the Ford vs. Chevy fire in us. I don't believe it is for your model, but you could probably get some sympathy warranty work out of it.

 

[LKirchoff68]

I am not sure which model he has, but at the team match we ran this weekend Jamesb74's Eotech did the exact same thing. It would mainly stop working after a lot of moving (ie. running and climbing obstacles.)

 

[diving dave]

Well after chatting with our range guys and some checking with Eotech I have found out the following..looks like all the models made after 3/07 have had changes made to the springs and battery contacts, to prevent the vanishing reticle . I looked on the under side of the issue optic, it was made in 6/06. Our unit has about 9 of them..Next week I'll try to find out if they need to go back, or something that can be just switched out.

 

[ArtFWTx]

Let me know what you find out about EOTech servicing these units. I know several guys who have older EOTechs made before that 3-07 date.

Well atleast you had back-up irons. I was at the range the other day and a local epartment guy was there w/ his G36 and an
EoTech, but NO irons at all. I asked what the departments idea was if/when the primary quit. All he said was "good question".
Said he was going to bring it up. BTW local SWAT uses Noveske's w/ irons for back-up. Not sure what their primary optic is.

Let me know what you find out also.

Yes mine took a big crap also in the 140 yd stage. We started at the beginnning and crawled over a low wall and then hit the deck to put 10 rounds in the target had to do this three times advancing down the range.
I checked the EO before we started to make sure it was on. Then climbed the first wall hit the deck and it was dead. Walked the shots in to the target. jumped over the second wall and it was on so proceeded. Then over the third one and it was dead again. And my dumbass hadn't sighted the BUIS after my hunting trip so I couldn't trust them in this case.

I know its my own stupid fault for not being prepared.

But after I send this in if that is the resolution I am selling it and getting an Aimpoint. I guess I am going to drink the Kool-aid on this one. I can't trust it again now that it has failed in the heat of things.

What was your manufacture date?
Before or after 3/07?

this is where these things usually end up. Fastest car in the race don't mean shit if it spends even so much as the last lap, let alone 20 laps, in the pits.

 

[Jamesb74]

It was before 3/07.
It says 6/06 on the bottom.

True. I learned two things from this.
Don't trust EO
and always make sure your damn sights are ready.

Now my 6.8 wears a Millet DMS until I can get a Talon. At least if the DMS fails it is just the illuminuated reticle the optic will still keep working. and then the BUIS is always there.

Actually, I prefer the hot chick analogy. EOTechs are high maintenance. LOL.
Ever since they switched to L3, the problems really started showing up. I want to see how the new XP models hold up. Don't see how it can be so hard to fix the battery compartment issues.

Allright, I'm confused, has the problem been fixed or not?

The 1st quote makes me think the problem is with older, pre 3/07 units.
The 2nd makes me think the problem is still continuing to this day.

I'm asking because I've got a brand new, still in the box, 556.A65/1 with a manufacture date of 8/08 waiting to go on my Xtreme build.
Is this one going to be OK or should I sell it and get something else?

Unfortunately, the only way to tell if it is going o work is to try it. Most EOTechs work fine, but their failure rate is definitely higher than Aimpoints. We have EOTechs on our Patrol Carbines and they work great, but we take care of them replace the batteries quarterly. I also periodically take the battery compartment off and take out the battery springs and clean them up and stretch them out a little bit. The battery compartment has been the biggest weakness with the EOTechs and no one has really figured it out. Most people think it is something to do with the battery springs and I agree with it. I think their new XP series is the step in the right direction. At least I hope for their sake or else they will be in some serious trouble.if they can't get their shit together. I'm going to give the XP series a try once they come out because I feel that when they work, EOTechs are the best red dot sights out there. But if the problems continue with the XP series, I'll stick with the Aimpoints.

I suggest you stick with the recommended batteries and quarterly or twice a year, take the battery compartment off and clean it up and stretch out the springs.

Thanks, what the hell, I'll stick with it and see what happens.
Maybe Wolff should start making some extra power replacement springs for EO battery compartments.
