Vortex Viper PST 4-16x50mm FFP Riflescope with EBR-1 (MRAD) Reticle

The Viper PST (Precision Shooting Tactical) riflescope boasts features associated with top-tier riflescopes, yet comes in at a street price under the $1,000 mark. Matching reticle and turret measurements allow accurate, fast dialing of shots. The one-piece 30mm tube, precision-machined from a single solid block of aircraft-grade 6061-T6 aluminum, offers ample windage and elevation adjustment. The Viper PST series delivers the performance and features tactical shooters demand at an economical price.

The Enhanced Battle Reticle is a hashmarked ranging reticle using MRAD based subtension lines for ranging, holdover, and windage corrections.

• First Focal Plane
• 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.

Internal Mechanism Design Features

• CRS Zero Stop: 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.
• 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: Professional-grade illumination: designed for daytime, low light and night vision devices. The top three settings (8, 9 and 10) are visible in the daytime, depending on the background color. Settings below 8 are for low light use when the users eyes have adjusted to lower light levels. Lowest settings are intended for use with night vision devices.
• 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. Positioned at the left side of the eyepiece.
