The Sig Sauer Sierra3 6.5-20x52mm BDX SFP Rifle Scope blends traditional optics with cutting-edge technology, redefining what’s possible in precision shooting. At its core lies the BDX (Ballistic Data Xchange) system, an intelligent link between your riflescope and a BDX-capable KILO rangefinder. Once connected via Bluetooth®, the scope displays an illuminated holdover dot, calculated automatically based on range, ballistics, and environmental data, giving you near-instant targeting precision. Simply range the target, connect the dot, and fire.
Engineered for clarity and performance, the Sierra3 BDX features SpectraCoat™ lens technology, providing ultra-wide broadband anti-reflective coatings for exceptional light transmission across the visible spectrum. The result is superior visibility and brightness, even in low-light conditions. Built with a 30mm main tube and a versatile 6.5-20x magnification range, it’s ideal for long-range hunting and shooting.
The BDX-R1 reticle sits on the second focal plane, combining traditional stadia lines with an OLED illuminated ballistic dot that scales automatically with zoom, ensuring consistent subtension at any magnification. For added confidence, LevelPlex™ digital anti-cant technology now features Auto LevelPlex, boosting sensitivity for longer shots. Meanwhile, KinETHIC™, Sig Sauer’s kinetic energy indicator, promotes ethical hunting by notifying you when shot energy drops below a custom threshold.
Equipped with MOTACâ„¢ (Motion Activated Illumination), the scope powers up when movement is detected and powers down when idle, preserving battery life while maintaining operational readiness. The housing is IPX-7 rated, ensuring waterproof and fog-proof performance in all conditions, and it's nitrogen purged for reliability in the field.
Built tough, feature-rich, and backed by Sig Sauer’s Infinite Guarantee, the Sierra3 6.5-20x52mm BDX is not just a scope, it’s an intelligent shooting solution that lets you simply connect the dot.
