Eh.. I just wonder how it would hold up to the .308 shock.
My rifle has an Eotech that has already done 2 tours of Iraq, on an M4, and a year and a half of hog hunting on the 308.
It was decommissioned from service when the battery terminals smacked loose, and they then upgraded the rifle it ran on with the XPS2, or 3, so the one I have went to the parts bin, even though it worked fine after the terminal was repaired.
After tour #2 ended, the armorer was told to clear out the bins of 'old, useless gear.' And, so it was deemed that the 512 would either be blown up or buried in the desert, or sent home. And that is how it eventually made its' way to me. Decommed, and signed off.
A year and a half of my hog hunting with the 308, and who knows how much abuse it saw riding with the Army. Holds a zero like a champ. And, FWIW, it's zero is pretty much the same whether it is mounted on an M4 or a 308. I guess rail height in relation to the barrel is pretty equal out to 75yds or so.
They are really well built. The only improvement one can do is the foam behind the battery terminal mod. This fixes any issue with the battery contacts.
