100 percent replacement, ouch, this little goof up by Eotech will end up costing tax payers a good ammount of money. I'm gonna say it first, glad I carry a M68 on my duty, and personal weapons

Was it the 553 or the 552 series? (my guess was the 552, which I've had no problems with either)

How will it cost the taxpayers ? Doesn't Eotech have the liability for the repairs ?

After extensive testing and discussions with EOTech, we've determined that the shut-off problem with the SU-231/PEQ reflex sight is systemic, which has resulted in a decision to temporarily stop further fielding of that item. A synopsis of the problem is as follows:

1. At the Shot Show, it was brought to the SOPMOD PMO's attention that a specific unit had seen an inordinate number of failures on the SU-231/PEQ Reflex Sight made by EOTech. The failure is characterized by the sight shutting off in the middle of weapon fire.

2. Upon returning from the Shot Show, we made a number of calls out to various units informing them of the potential failures and asked them to keep an eye out. Since that time, we've received several notifications of similar failures. EOTech has been able to replicate this failure at their factory. At the same time, SOPMOD pulled ten sights from Supply and tested them. We were able to replicate the failure on eight of those ten sights and have sent all the tested sights to back to EOTech.
The initial failures occurred at 1,500 round on the low end and 7,500 rounds on the high end. The root cause is that after the DT/OT but prior to the MS-C, EOTech changed suppliers for the battery contacts on the main housing.
Although EOTech's Quality procedures require them to maintain control of their suppliers, which includes qualification of parts, the new parts were of lesser quality than the parts that were in the DT/OT sights. The result is that the battery contact on the positive side is becoming fatigued and is failing due to weapon shock (see attached photo).

3. EOTech has qualified a new supplier of the battery contacts and has installed these new components into some SU-231/PEQ's, which have been able to withstand 10,000+ rounds of simulated fire on their simulator.
Additionally, they made some improvements to the battery housing. They are in the process of sending those sights back to Crane for validation.
Over the next few weeks, we are going to test a number of these upgraded sights received back from EOTech, to include 10,000+ simulated rounds on each sight plus an immersion test to make sure the seal is not compromised.
Once we are convinced that the quality is back to the original baseline, we will commence with a 100% warranty repair of all sights that are still at Crane, which exceeds the total number of SU-231/PEQ's that have been issued.
EOTech has indicated that they can do the warranty repair on-site at Crane.
Once the sights have been repaired and returned to "A" condition, we will be sending out SOPMOD Maintenance Contact Teams to every Command Unit that has been fielded SU-231/PEQ's and will do a one-for-one exchange. For deployed units, we will perform the one-for-one exchange when they rotate back from overseas. In the meantime, I am generating a message to send out to all components alerting them of the problem with the recommendation that all operators temporarily cease using them until they can be replaced.
Additionally, I am requesting that no further SU-231/PEQ's be fielded until the matter is resolved. Additionally, I am asking all concerned to cease fielding the SU-231/PEQ's until the matter is resolved.

Oh shit

So does this mean everyone who owns a 553 will eventually have to send it in for replacement? Is this free?

Aimpoint FTW


Seriously though...I like the EO but like the AP more. EO's are quick and unique w/ their reticle and wish I could get the durability and hours of an AP w/ an EO reticle.

i was having this issue back in the fall with my 553...i sent it in a few weeks ago and they sent me a brand new one within a few days.

i didn't realize it was a larger problem. i am extremely happy with EOtechs customer service and will continue to use them.

Tag for the I told you so factor

On the bright side those who have been wanting one will probably be able to get a real good deal on a factory refurbished model in the near future,

Almost every company will have somehting like this happen a time or two in their history. The mark of a good company is how they deal with making it right.

Don't know why anyone should be surprised by this...
This has been observed by Certain folks for years as a known issue with these sights...

Springs compressing by the batteries due to recoil.....


As I sit here and fondle my 4 yr old M2 Aimpoint that is on it's second battery.....

Game on all your EO Tech Lovers....

Mine did this in rifle league a couple of times, I took out the springs and stretched them, everythings fine now, no more issues.
