Sig Sauer BDX Combo Kit

Everything you need to get the most accurate and ethical shot every time.

The Sig Sauer BDX Combo Kit is a three-piece ranging and aiming solution for modern hunting rifles. The combo kit comprises the SIERRA3BDX riflescope, KILOBDX rangefinder, as well as the SIG BDX (FREE) app — available for Android and iOS smartphones. When combined, the three pieces work in concert to provide an accurate aiming point perfect for any hunting situation.

How does BDX work?

The BDX rangefinder and riflescope system is simple, fast, and intuitive. Simply download the “SIG BDX” app available for Android or iOS smartphones, pair the KILO BDX rangefinder and SIERRA3BDX riflescope, set up a basic ballistic profile, and then you’re ready to shoot or hunt. Once you are in the field, range your target as you normally would, and the KILO BDX rangefinder will utilize onboard Applied Ballistics Ultralight™ to instantly send your dope to the scope via Bluetooth. Using your basic ballistic profile the ballistic solution is calculated for your target and will instantly illuminate on the BDX-R1 Digital Ballistic Reticle with windage and elevation holds in the SIERRA3BDX riflescope. A blue LED on the riflescope power selector indicates that the BDX system is paired, and when the reticle has received new ballistic holdover and windage data from the rangefinder.
