Ok so I was planning on getting a VX1 leopold, (3-9x40) as the other leopolds are out of my price range, but I have stumbled on a deal on a Mark AR leopold, for within 20$ or so of what I expected to pay for a VX1.. the Mark AR has the same lenses as the Mark 4's, and has a BDC. (admittedly it has a .223 bdc drum, but that is easily remedied.. (it's for a .308) So what do you all think? anyone have any experience with the Mark AR's?
