The world of long-range shooting and hunting just received a game-changing innovation in the form of the SIG Sauer Sierra3BDX riflescope and the entire BDX system. This unique setup enables users to get on target with the first shot, thanks to an incredible ballistic calculator. In conjunction with the rangefinder, the SIG Sauer Sierra3BDX riflescope takes a user's unique ballistic profile, loaded with rifle and ammo selections, and calculates the trajectory together with range. A bright spot illuminates the reticle with the exact holdover point needed. Second focal plane reticle Weight: 25.9 ounces 6.5-20x52mm size Adjustment value: 1/4 MOA Otherw Mfg: Sig Sauer, Inc.
