Vortex Optics Viper HD 5-25x50 FFP VMR-4 (MOA) 30mm Tube Riflescope (VPR-52501)
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.
Key Features
- 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.
- Argon Gas Purged: Gas purged and O-ring sealed for fogproof and waterproof performance in all conditions.
- Fast Focus Eyepiece: Allows quick and easy reticle focusing.
- Aircraft-Grade Aluminum: Constructed from a solid block of aircraft-grade aluminum for strength and rigidity.
- Low Glare Matte Black Anodize: Corrosion and wear resistant anodization provides low-glare matte surface.
- Single-Piece Tube: Maximizes alignment for improved accuracy and optimum visual performance, as well as ensures strength and waterproofness.
- Waterproof: Designed to withstand harsh weather conditions.
- Fogproof: Nitrogen gas purging prevents internal fogging over a wide range of temperatures.
- Shockproof: Designed to withstand the highest levels of recoil and impact.
