I am selling my mint condition Eotech 558 model for 650. They retail for 750 to 800 after taxes. I'm firm on the price. Some People complained about the battery life on the EXPS3-0. With about 600 to 800 hrs of battery life. So the made the same model but with AA batteries for more life. Abiut 2000 hrs. I know it still doesn't compare to holosun and others with about 50k hrs but its an eotech. It comes with a limited edition box. It had a g33 with it but sold it. Well you can reach me at 830-262-1689 and I can meet you off of 410 and bandera. Also this is the night vision model. I will not respond to TGT messages. Too many bots. Text for faster response.
