    Disguised within the form factor of a traditional riflescope lies the power of the SIG SAUER BDX Ballistic Data Xchange. The SIERRA3BDX riflescope provides an illuminated auto-holdover dot on targets when coupled with a BDX capable KILO rangefinder. Featuring exceptional SpectraCoat lenses, Level Plex digital anti-cant, and Kinetic kinetic energy transfer indicator, the SIERRA3BDX is incredibly simple to use. SIG SAUER’s BDX, just CONNECT THE DOT.
    Key Features:
    • Integrated BDX Ballistic Data Xchange. A rangefinder and rifle scope system that uses ballistics, environmental conditions and Bluetooth.
    • Automatic holdover dot on a Digital Focal Plane, combining Second Focal Plane studies, with an OLED illuminated ballistic holdover dot.
