Sig Sauer Sierra3 BDX 4.5-14x44mm | BDX-R1 | 30mm

The Sig Sauer Sierra3 BDX is a digitally enhanced variable-power riflescope that integrates the BDX Ballistic Data Xchange system for range-based holdover. It pairs a Second Focal Plane BDX-R1 digital ballistic reticle with SIG’s LevelPlex anti-cant, KinETHIC energy indication, and MOTAC motion-activated illumination to support field use. The scope is built for practical long-range and medium-range applications, including hunting and precision target shooting, where ballistic compensation and quick target engagement are priorities.

The Sierra3 BDX brings digital ballistic tools into a traditional riflescope form factor: automatic, magnification-scaled holdover dots and app-driven ballistic profiles simplify range-based aiming in dynamic field conditions. Its combination of electronic functionality and conventional glass optics is intended to reduce on-target calculation and let the shooter focus on follow-through and shot execution.
