I'm considering moving my current AR scope to a bolt action and trying one of these out. There are a lot of AR marketed scopes out there now, but with the Mark 8 at $3000, it's not all reasonable. I'm considering the 2.5-8x Nikon M223 or the Luppy Mark AR 3-9. I lean towards the Nikon because I have a Nikon tactical on the gun now that is nearly perfect except it's big. And, the M223 2.5-8 is small. The Mark AR offers custom turrets and that's a puls because I do not shoot 55 gr at all. both scopes have BDC's tuned around the 55. I don't see that the Nikon offers any fix though.

Has anyone used either? I'd like to hear more about these specific scopes, especially relating to longer range shooting (past 400 yards).
