Vortex Optics 1-4x24 FFP Viper PST Riflescope, Matte Black Finish with Illuminated EBR-5 MOA Reticle, 30mm Tube

Specifically designed for the military, law enforcement and committed precision shooting communities, the Vortex Optics Viper PST 1-4 x 24 FFP Riflescope, EBR-5 Reticle, MOA, Low Capped Turrets (PST-43109) offers the highest levels of performance and reliability. With features such as matched turret/reticle subtensions, CRS zero stop mechanisms and precision ranging reticles, the Viper PST is ready for any situation.

The Viper PST (Precision Shooting Tactical) is built on a precision-machined, one-piece aircraft-grade aluminum tube protected by a type-3 hard-anodized finish. The large diameter 30 mm tube provides additional strength and rigidity, as well as extra room for extreme range elevation adjustments. The construction is 100% waterproof, dustproof and fogproof - purged with argon gas to prevent internal fogging and corrosion.

This riflescope uses a first focal plane reticle. This style of reticle maintains its subtensions regardless of magnification change - the reticle appears to grow and shrink as the magnification changes. The main advantage to this style reticle is that the reticle subtensions used for ranging, holdovers and wind drift corrections are always accurate at any magnification. XR coatings deliver incredible image detail with extremely high resolution and light transmission. XD (Extra-low Dispersion) glass objective lens elements made of extra-low dispersion glass enhance image resolution and are carefully selected and precision crafted to exacting standards for true-to-life images of startling clarity and color accuracy.

This Viper PST riflescope does not have a parallax focus. The focus is factory pre-set at a distance of 100 yards. ArmorTek is an ultra-hard, scratch-resistant lens armor, chemically bonded on the outer glass surfaces. ArmorTek's unique stain-proof topcoat features a slippery surface that actually repels the oil and corrosive salts from fingerprints. Dust, dirt and smudges are easily wiped away without fear of scratching the optical glass beneath. The EBR-5 MOA reticle is a hash-marked ranging reticle using MOA based subtension lines for ranging, holdover and windage corrections.
