You can not use the night piece you see on the scope in the pictures during the day. The picture shows the day time eye piece next to the scope. It is not green with the day eye piece its clear just like any other scope. Its 2.5x10x56 just like any other scope on the market. There about $7500 and mostly the Gov buys them. Get it while you can.. Have a lot of people interested.. Dealer cost is $6500
