Deal of the Day by Webyshops: VORTEX Viper PST 4-16×50 FFP Riflescope

Specifically designed for the military, law enforcement and committed precision shooting communities, the¬†VORTEX Viper PST 4-16×50 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.
