HD Optical System - Optimized with select glass elements to deliver exceptional resolution, cut chromatic aberration and provide outstanding color fidelity, edge-to-edge sharpness and light transmission.
Illuminated Reticle - Provides precise aiming under low-light conditions.
30mm Main Tube - For increased travel.
Exposed Locking Elevation Turret - Integrated locking mechanism prevents accidental adjustments. Elevation turret provides fast, accurate, easily read elevation adjustments.
First Focal Plane Reticle - Scale of reticle remains in proportion to the zoomed image. Constant subtensions allow accurate holdover and ranging at all magnifications.
RevStop® Zero System - For a rock-solid return to zero after turret adjustments.
Fully Multi-Coated Lenses - Anti-reflective coatings on all air-to-glass surfaces provide increased light transmission for greater clarity and low-light performance.
ArmorTek® - Ultra-hard, scratch-resistant coating protects exterior lenses from scratches, oil and dirt.

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.
