“The ultimate flexibility in bullet drop compensation”

  • Don’t settle trying to match your load with a BDC or busy MOA reticle.
  • Purchase a Kenton custom knob and hunt anywhere in the world using our calculator.

Benefits of a Kenton Custom knob and calculator:

  1. The calculator will compute the adjustment for changes in shooting altitude, temperature, bullet, or muzzle velocity.
  2. Provides the required adjustment in yards to your custom knob.
  3. Works with the main crosshair on any 1st or 2nd focal plane reticle and on any magnification setting.
  4. Calculates the required zero range when sighting in for a different bullet or new field conditions.

There is no other system which provides an inexpensive, flexible, and fast way to engage targets.
