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.
