I have had no issues with my optic to date and the only reaason I'm looking into selling it is I won some EoTech with thier millionth sight promotion they had on Facebook.  I know there were some that had issues but this one has been true up to date and I would think it would have had a problem by now if it was going to have one.  Just looking to see what the going rate is before I post it in the EE. Thanks for any input. Last I saw they were going for $250.

Which optic is it?  The original stg. 556 low scope or the higher E4/ original AUG looking one?

It's the lower one.

$250 is the ballpark. I sold mine off a couple of years ago for that price and mine was a dead nuts spot on unit also. It still works to this day as I keep in touch with the buyer.

as they get harder to find the price "could" walk upward some for the proven units.

$250 is usually about what I see them sell for. I'm glad I opted for the optic equipped model when I bought mine, at the time it was only ~$100 more.
