The heart of the B.E.A.S.T. is its i4F intelligent four-function elevation control. Initial adjustments with the primary elevation knob are lightning fast, in .50 MOA/.2 Mil-Radian increments. An integral fine adjustment lever provides additional elevation adjustments in .25 MOA/.1 Mil-Radian increments. XtremeSpeed provides 60 MOA (20 Mil-Radians) of adjustment instantly in a single rotation (120 MOA total travel) meeting, or exceeding, the effective range of any known cartridge at extreme distances.
