Sig Sauer Sierra4 BDX 6-24x50mm 30mm Tube SFP BDX-R2 Rifle Scope

The Sig Sauer Sierra4 BDX riflescope brings digital ballistic compensation to long-range hunting and precision shooting. Built around Sig Sauer's BDX (Ballistic Data Xchange) ecosystem, the Sierra4 BDX pairs with a compatible BDX-enabled rangefinder or Kestrel unit to deliver real-time hold points through an integrated network of 194 individually addressable LEDs embedded in the BDX-R2 Digital Ballistic Reticle.

The scope covers a 6-24X magnification range behind a fast 50mm objective, all built on a rugged 30mm main tube for serious elevation and windage adjustment. The Sierra4 BDX delivers over 48 MOA of total elevation travel, giving long-range shooters the dial-in range they need for distance work. The Second Focal Plane (SFP) reticle keeps subtensions consistent at every magnification setting, and click adjustments come in precise 0.25 MOA increments for fine dialing.

Measuring 13.9 inches overall and weighing 24.4 ounces, the Sierra4 BDX is finished in non-reflective matte black to blend with virtually any rifle platform. The illuminated reticle uses red illumination for clear aiming points in low light, while the digital ballistic network makes holdovers intuitive once the scope is paired and zeroed. This is new Sig Sauer factory production, ready to mount to your favorite long-range rig.
