Product Info for SIG SAUER SIERRA3BDX 45-14x44mm Riflescope SOSBDX34111

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 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 target, pull the trigger, impact. SIG SAUER's BDX, just CONNECT THE DOT.

Advanced optical systems comprising both High Definition (ED) and High Transmittance (HT) glass for ultra-high resolution, optical performance and light transmission.

Activated through motion sensing technology, MOTAC immediately powers up illumination when it senses motion and powers down when it does not in order to extend battery life.

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.

Stealth ID
Electro-Optics industrial design inspired by our legendary firearms; deflection armor trapezoidal surfacing breaks up the shape and visibility of the optic along with pistol slide serrations and grip checkering to add function to the form of all SIG SAUER electro-optics.
