The Heras SPR 15-60x56mm Riflescope is an ideal choice for Bench Rest Shooting, F-Class, or any other shooting application that demands maximum precision. To ensure a lifetime of reliable service, the Heras SPR 15-60x56mm utilizes a one-piece tube design made from heat treated aircraft grade aluminum. This gives the Heras SPR ideal resistance to shock, recoil, and minor bumps and impacts. The Heras SPR’s optics feature premium glass lenses with advanced multi coatings to deliver superior light transmission with optimum brightness and true color across the entire light spectrum. Other features of the Heras SPR include a lockable windage turret, allowing the user to pull the turret up to make adjustments, and push it down to lock it in place to prevent unintentional adjustments. The locking turrets are perfectly complemented by the Precision Zero Rest Function that allows you to return to your original zeroing after making adjustments in the field.
