The Viper PST Gen II brings you all the features of elite, top-tier tactical optics at a fraction of the cost. The 5X optical system delivers bright and crisp images across the zoom range with an impressive field of view for quicker target acquisition. Exposed turrets provide ample range of adjustment for dialing long-range shots and always match the reticle. After a day of dialing at extended ranges, the integrated, mechanical, RZR zero stop will bring you back to your exact zero every time with positive engagement. More on the EBR-7C MOA reticle Designed to maximize long-distance shooting and ranging abilities, the EBR-7C MOA 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 MOA specifications are kept to the tightest tolerances possible. The fine center crosshair subtensions on the EBR-7C MOA reticle were carefully chosen to provide the optimum balance between precision aiming and low-light visibility. Includes windage reference dots on drop lines. With the Vortex VIP Warranty, you get a Very Important Promise. The Vortex VIP Warranty is about how its handled, not how it happened.
