Why we like this product

  • Integrated BDX Ballistic Data Xchange rangefinder and riflescope system uses ballistics, environmental conditions, and Bluetooth to illuminate the exact holdover dot needed
  • Automatic holdover dot on a Digital Focal Plane, combining Second Focal Plane with an OLED illuminated ballistic holdover dot that automatically scales with zoom to subtend on target at any magnification level
  • Features MOTAC motion-activated illumination that powers up when it senses motion and powers down when it does not
  • SpectraCoat anti-reflection lens coatings reduce surface reflections to extremely low levels across the entire visible spectrum providing superior light transmission
  • Innovative KinETHIC kinetic energy transfer indicator assures an ethical hunt by indicating when energy on target drops below a set threshold
  • LevelPlex automatically increases digital level sensitivity on longer shots without the need for an external bubble level
  • Dependable waterproof IPX-7 rated for complete immersion up to 1 meter and fog-proof performance

The Sig Sauer SIERRA3BDX 3.5-10x42mm BDX-R1 Digital Riflescope takes traditional riflescopes into the future with the ability to provide an automatic holdover dot. Using Bluetooth technology, your BDX-capable KILO rangefinder provides real-time ballistic solutions and transfers those solutions directly to the riflescope in the form of an automatically illuminated holdover dot. Place the dot on the target, press the trigger and impact. The SIERRA3BDX features LevelPlex a digital anti-cant system that utilizes an integrated digital level with cant indicators inside the riflescope that is 6x more accurate than a traditional bubble level. A new and innovative KinETHIC Kinetic Energy Indicator allows the shooter to set a threshold in either ft-lbs or fps for an ethical harvest of game animals. The BDX system will compute the distance ranged and will indicate to the shooter when you drop below those set thresholds so you know not to take the shot until you can close more distance. Weighing at about 1.5 lbs and in a 4.5-14 power range, this scope is built for any hunting scenario.
