Sig echo 1-2 30mm thermal reflex sight.....just purchased and then came across a better opportunity a few days later....purchased from original owner and its cosmetically a little rough but it functions as it should. Just paid 710 plus fees to total 780 September 24th which you can see in one of the pics attached. Selling for 679 or best offer. My loss is your gain.....may consider trade offers but prefer cash
