SIG Sauer announced the SIG BDX rangefinder-riflescope system back in May. As seen with many of its other releases, SIG brought the innovation.

How does the BDX — which stands for “Ballistic Data Xchange” — work? Start with a download of the “SIG BDX” app available for Android or iOS smartphones. Once you have that, pair your phone with the KILO BDX rangefinder and SIERRA3 BDX riflescope, set up a basic ballistic profile, and you’re ready to shoot.

In the field, range your target as you normally would. The KILO BDX rangefinder utilizes 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. It also indicates when the reticle receives a new ballistic holdover and windage data from the rangefinder.

We tested the KILO1800 BDX Rangefinder with the SIERRA3 4.5-14x44mm riflescope at the 2018 Athlon Outdoors Rendezvous. It almost makes things too easy, but we’re not complaining. MSRP on that kit is $1,079.99, which is pretty insane (cheap) when you consider what you’re getting. MSRP on other kits start at $839.99.
