Bullet Drop Compensator

All of the professional lit-reticle riflescopes have a built in adjustment that compensates for bullet drop. The elevation dial is calibrated for bullet drop in increments from 100 yards to 500 yards. This innovation eliminates the need for complicated ballistic calculations and puzzling aiming patterns. In case the user needs to take a shot at different distances, the alignment process is simplified to the quick turn of a knob.

Bullet drop compensation is only possible for certain caliber's, with specific weights and muzzle velocity:
