SIG Sauer SIERRA3BDX 6.5-20x52mm (30mm) BDX-R1 Illuminated Riflescope

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 Sierra 3 BDX is incredibly simple to use. Range a target, put the holdover dot on target, pull the trigger, and impact!

  • HDX™ advanced optical system with both High Definition (ED) and High Transmittance (HT) glass for ultra-high resolution and light transmission
  • KinETHIC kinetic energy transfer indicator tells when energy on target drops below threshold set by hunter using SIG BDX app
  • Auto LevelPlex automatically increases digital level sensitivity on longer shots
  • BDX-R1 Digital reticle
