The Viper PST 6-24x50 Second Focal Plane boasts features associated with top-tier scopes. The one-piece, shock proof 30mm tube, precision-machined from a single solid block of aircraft-grade aluminum, offers ample windage and elevation adjustment. Matching reticle and turret measurements allow accurate, fast dialing of shots. The EBR-1 is a hashmarked ranging reticle using MOA based subtension lines for ranging, holdover, and windage corrections.
