Designed to maximize long-distance shooting and ranging abilities, the VMR-4 reticle can be used to effectively determine ranges, holdovers, windage corrections, and moving target leads. Ultra-precision laser etching on the glass reticle ensures that specifications are kept to the tightest tolerances possible. The fine center crosshair subtensions on the VMR-4 reticle were carefully chosen to provide the optimum balance between precision aiming and low-light visibility. Includes windage reference dots on drop lines.
