This riflescope is engineered for hunters and shooters who want to leverage digital technology for fast, precise aiming solutions. When paired with a Sig Sauer BDX rangefinder and the BDX app, the SIERRA3 BDX automatically calculates and displays the correct holdover point on the illuminated reticle, taking into account distance, angle, and environmental data. This system streamlines the shooting process, reduces manual adjustments, and enhances accuracy, especially at extended ranges. The rugged, waterproof build ensures reliable performance in challenging outdoor conditions.
