You got a good deal imo. I think at $300 new they are a good deal. Its got a t2 1/2 moa elevation turret marked in yardages for a 223, but also has moa markings so you can run it on other cartridges too. From what I understand its a vx2. Im running one on a 270 win and like it so far.
Correct. The 6-18x40 is the only Mark AR that has 1/4 moa...I have the 6-18x40 on an AR and it shoots submoa all day! Great scope... But its a leupold So you allready knew that!
And yes Ebay is about the best place to buy them new and they are 300 on there... Good deal!
