Disguised within the form factor of a traditional riflescope lies the power of the Sig Sauer BDX Ballistic Data Xchange. The Sierra3bdx riflescope provides the hunter with an illuminated auto-holdover dot on targets when coupled with a BDX-capable KILO rangefinder. Featuring exceptional SpectraCoat lenses, LevelPlex digital anti-cant, and KinETHIC kinetic energy transfer indicator, the Sierra3bdx is incredibly simple to use. Range a target, put the holdover dot on the target, pull the trigger, and impact.
Integrated BDX Ballistic Data Xchange
The Integrated BDX Ballistic Data Xchange is a rangefinder and riflescope system that uses ballistics, environmental conditions, and Bluetooth to illuminate the exact holdover dot.
Automatic Holdover Dot
Automatic holdover dot on a Digital Focal Plane, combining Second Focal Plane stadias, with an OLED illuminated ballistic holdover dot that automatically scales with zoom to subtend on target at any magnification level.
Motion Activated Illumination
Features MOTAC (Motion Activated Illumination) that powers up when it senses motion and powers down when it does not. It provides for optimum operational safety and enhanced battery life.
Anti-Reflection Lens Coatings
The Spectracoat's highly efficient, ultra-wide broadband, anti-reflection lens coatings reduce surface reflections to extremely low levels across the entire visible spectrum providing superior light transmission.
KinETHIC Kinetic Energy Transfer Indicator
KinETHIC assists in assuring an ethical hunt by indicating when energy on target drops below a threshold that can be set by the hunter using the SIG BDX App.
Auto LevelPlex
New for BDX riflescopes, the Auto LevelPlex automatically increases digital level sensitivity on longer shots.
Waterproof and Fogproof
Dependable waterproof (IPX-7 rated for complete immersion up to 1 meter) and fog-proof performance.
