When used together Sig Sauer KILO BDX rangefinders and SIERRA3BDX combine to create the most advanced optics system available on the market today. Simply configure your ballistics profile in the BDX app, pair your KILO BDX rangefinder with the app, and then bond it to your SIERRA3BDX. When you range your target the KILO BDX rangefinder automatically sends your specific holdover data to your SIERRA3BDX giving you an illuminated holdover dot. It’s simple and fast.

These rangefinders include many of the legacy features that the KILO name was built on: Lightwave DSP™ digital rangefinder engine, Hyperscan with 4 times per second scan rate, RangeLock, and the Lumatic auto-adjusting display.

Available in 2.5-8x32mm, 3.5-10x42mm, 4.5-14x44mm, 4.5-14x50mm, and 6.5-20x52mm, the SIERRA3BDX have the look, feel, weight, and size of traditional scopes. They feature HD glass for superior resolution and optical clarity, 30mm main tubes, side-focus parallax adjustments, and the LevelPlex digital anti-cant system. The BDX-R1 Digital Ballistic Reticle is the evolution of holdover, providing a ballistic solution out to 800 yards with 1 MOA of accuracy.
