The Viper PST Gen II brings you all the features of elite, top-tier tactical optics, with exceptional performance 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, are available in MOA or MRAD 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.SpecificationsMagnification 3 15Objective Lens Diameter 44 mmEye Relief 3.4 inchesField of View 41.2 8.6 feet/100 yardsTube Size 30 mmTurret Style TacticalRZR Zero StopAdjustment Graduation 1/4 MOATravel per Rotation 25 MOAMax Elevation Adjustment 75 MOAMax Windage Adjustment 40 MOAParallax Setting 20 yards to infinityLength 14.3 inchesWeight 28.1 ouncesOptical FeaturesXD Lens Elements Extra-low dispersion (XD) glass increases resolution and color fidelity, resulting in crisp, sharp images.XR Fully Multi-Coated Proprietary coatings increase light transmission with multiple anti-reflective coatings on all air-to-glass surfaces.First Focal Plane Reticle Scale of reticle remains in proportion to the zoomed image.
