Instead of an M1 turret,and sending your scope in, Leupold now has knurled turrets that connect to the coin slot style adjustment. You can get them with your given ballistic data, or simply mils or MOA.
I just ordered one for a 2.5-8 that runs exclusivey MK262 Mod 1, and another that is set for MOA.
It was 50 for the generic MOA dial and 60 for the MK 262 turret.
I will let y'all know when I get them and test them out at the range. for accurate comeups.
