I have a very good friend who is an army sniper (from Vietnam) with a bronze star and a couple of purple hearts. I have been taking him out shooting lately mid range distance 700-1000 yards. He has a m1a and keeps talking about this ART scope. I have tried to find a little bit about the scope. So if you have any information on one I would like to know. I have seen them in price from $700-1000 on bidding web sites with no bids. So what can I expect to actually pay for one. I am looking to purchase one for him.
