Leupold 3.5x10 mil dot and 30mm tube or Leupold Mark IV M1 (with 1/4" click adjustment for both windage and elevation). I prefer the latter over the Mark IV M3 which has the bullet drop compensator (BDC). The BDC works for 168 grains, but what if you handload and your trajectory is different? Granted the M1 is slower, but it is more precise and with a precision rifle, shot placement takes precedent over speed.
