Description
New, sealed, SIG SAUER BDX long-range shooting package featuring the SIERRA3BDX 6.5-20x52mm SFP riflescope, KILO2800BDX laser rangefinder, and SIG SAUER ALPHA MSR scope mount.
This is much more than a scope and rangefinder—the BDX system allows the rangefinder and riflescope to communicate wirelessly and automatically provide a ballistic holdover solution.
The magic of this setup is SIG’s Ballistic Data Xchange (BDX) technology.
After setting up your rifle/ammunition ballistic profile, the system dramatically simplifies making a corrected shot at an unknown distance:
1. Range the target with the KILO2800BDX.
The rangefinder determines the target distance and calculates the ballistic solution.
2. The KILO2800BDX wirelessly sends the solution directly to the SIERRA3BDX scope.
3. The scope automatically illuminates the correct holdover point in the reticle.
Instead of ranging the target, checking a ballistic chart, calculating your drop, dialing elevation, and then getting back on target, the BDX system can essentially turn the process into:
RANGE → AIM AT THE ILLUMINATED HOLDOVER → SHOOT
That is the real advantage of BDX.
WHY IT’S SO USEFUL
For hunting or practical long-range shooting, targets don’t always wait around while you work through a ballistic solution. BDX integrates the rangefinder, ballistic calculation, and riflescope into one system.
