Mine are the 6.5-20x50 LR and the 8.5-25x50 LR. I also have them on a couple black guns with the mark ar dials. You can have the standard scopes converted by sending them in to leupold. The dials are like 60.00, not sure what the fee is to have them upgraded to take the turrets. I have never done that to any of mine. If you want one right out of the box to take turrets get the cds or lr/target models.
