Post the results of your zero drift.
The only FACT I care about is that my sight holds zero.
I don't have to read anything online to confirm this FACT.
If I have an issue, I will send it back.
I don't have any Eotechs, and neither do I sell them, or recommend them to any of my customers. All of my professional customers that have them in their inventory, are in the process of returning them to the manufacturer, and replacing them with Aimpoints. And by professional customers, I am referring to those guys and gals that spend their lives kicking in doors and going toe to toe with bad people, I guess you would refer to them as "operators".
I happy for you if your sight works for you, what with you doing cqb and all.
If by fact, you are referring to the exact sight you own, it is unlikely that you will find anything posted about it online, unless you posted something about it.
If by fact, you are referring to Eotech sights in general, including the same model as the one you own, you are just showing your complete and utter ignorance, given that the manufacturer has admitted that the zero drift is a real thing. Maybe you should post your sight back to them so they can see what they did when they built your sight, and use that knowledge to fix all the other ones.
The feeling at CANSOF/JTF2 and other organizations is that this issue could sink the company (Eotech, not L3), and if that occurs, there will be nowhere for you to send your sight when you eventually experience an issue with it.
Regards.
