~*Sold*~ Pictures will be up when I get home from work. I am selling an Eotech 512 series that takes AA batteries. I bought it used from the barons den in Eugene and it came with no manual or box. It's been used, but not abused. It has the older flat controls like the one in the picture (if you can see it). It also has the night vision setting. This sight has never given me a single problem and it holds zero perfectly. I'm asking $275 O.B.O. This has also been posted on craigslist and preference will go to whoever puts cash in my hand the quickest. Actual picture will be on later tonight. Until then, a stock photo: stu - To answer your question, no. I have had no problem with the batteries draining prematurely. It is still running the same batteries I installed when I bought the sight a year and a half ago and it they still work great.
