The Vortex Viper PST Gen II 3-15x44 FFP riflescope provides you with all the features of an elite, top-tier tactical riflescope, with exceptional performance at a percent of the cost. The 5x optical system delivers bright and crisp images across the magnification range with an impressive field of view for quicker target acquisition. Exposed turrets provide ample range of adjustment for dialing long-distance shots. It is available in either the EBR-7C (MOA) or EBR-7C (MOA) 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. The scope is on a 30mm tube. Adjustments are at 1/4 MOA.
