Specifically designed for the military, law enforcement and committed precision shooting communities, the VORTEX Viper PST 4-16x50 FFP Riflescope, EBR-1 MRAD Reticle (PST-416F1-M)
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 30mm 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 model 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.
The Viper PST FFP riflescope uses a side focus parallax adjustment which, when properly set, eliminates parallax errors. Parallax is a phenomenon that results when the target image does not quite fall on the same optical plane as the reticle within the scope. When the shooter's eye is not precisely centered in the eyepiece, there can be apparent movement of the target in relation to the reticle, which can cause a small shift in the point of aim. Parallax error is most problematic for precision shooters using high magnification.
Matching (mrad or MOA) turrets and reticles facilitate fast, accurate range calculations. Unique, stackable shims provide a zero-stop under the elevation turret, and the patent-pending fiber optic Radius Bar turret rotation indicator visually tracks revolutions.
Tall uncapped turrets are O-ring sealed for absolute waterproof performance and feature precision-machined turret screws. Finally, the Precision-Force system, using the heavy-duty aluminum alloy erector tube and a single zero-memory chromium vanadium erector spring, provides precision and predictable tracking.
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.
Designed to maximize long distance shooting and ranging abilities, the EBR-1 MRAD 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 mrad specifications can be kept to the tightest tolerances possible. The fine center crosshair subtensions on the EBR-1 MRAD reticle were carefully chosen to provide the optimum balance between precision aiming and low light visibility.
Born from an intimate understanding of riflescope design, forward-thinking engineering, and open ears to a market incredibly vocal about what it wants in a riflescope, the Viper PST riflescope delivers the performance and features tactical shooters demand at an economical price.
The Viper PST 4-16x50 FFP Riflescope comes with 4-inch sunshade, CR2032 battery, CRS shims and the VIP Unconditional Lifetime Warranty.
First focal plane subtensions remain consistent throughout the magnification range
Optically indexed lenses delivers optimum image sharpness and brightness with true reticle use for full ranging and holdover from edge to edge because of computer-controlled alignment during construction
XD Lens Elements provide the edge-to-edge sharpness needed to differentiate details at any distance
XR Lens Coatings increase light transmission with multiple coatings on all air-to-glass surfaces
30 mm tube provides greater strength and wider adjustment lattitude as compared to a 1-inch tube
One-piece tube maximizes alignment for improved accuracy and optimum visual performance as well as strength and waterproofness
Aircraft-grade aluminum construction from a solid block of 6061-T6 aircraft-grade aluminum delivers increased strength and rigidity
Waterproof, fogproof and shockproof
Type-3 hard-coat anodization is durable; the low-glare matte helps camouflage the shooter's position
ArmorTek - ultra-hard, scratch-resistant coating repels oils and corrosive salts on outer glass surfaces
Customizable Rotational Stop (CRS) prevents dialing more than one rotation below your zero so you don't lose the zero when dialing large amounts of elevation corrections
Tall uncapped turrets make range calculation and shooting adjustments fast and accurate with subtension marks that match the reticle
First focal plane reticle - scale of reticle remains in proportion to the zoomed image. Constant subtensions allow accurate holdover and ranging at all magnifications - no shift in point of impact during zoom
Single spring construction fully constrains (without over-constraining) the optical system for predictable, improved accuracy throughout the range of elevation adjustment
Glass-etched reticle protected between two layers of glass (not made from wire) for optimum durability and reliability
Illuminated reticle - electronic illumination aids in low light visibility of reticle (Battery included)
Illumination control can be turned on or off with a single click between each intensity level - allowing access to a preferred illumination setting without having to progress through each intensity level
MagView bar combines a fiber optics magnification indicator with raised rear-facing magnification references for clear viewing in low light conditions
Radius bar fiber optic turret rotation indicator provides illuminated and tactile point of reference for turret rotations
Fast focus eyepiece allows quick and easy reticle focusing
Side parallax uses an adjustment mechanism on the left side of the riflescope to fine-tune focus to eliminate parallax shooting error
The EBR-1 MRAD reticle uses mrad based subtension lines for ranging, holdover, and windage corrections
