Sig Sauer Electro-Optics Sierra6 BDX 3-18x44mm 30mm Tube Illuminated BDX-R2 Riflescope

The Sig Sauer Sierra6 BDX 3-18x44mm riflescope packs a 6x erector system into a compact, lightweight package built for hunting and long-range precision shooting. As part of Sig Sauer's BDX (Ballistic Data Xchange) platform, this scope pairs with a compatible BDX rangefinder over Bluetooth to receive ballistics, environmental data, and range information, automatically illuminating the precise holdover dot for the shot at hand.

Optically, the 3-18x magnification range paired with a 44mm objective feeds Sig Sauer's HDX 6x optical system, treated with SpectraCoat anti-reflection coatings for edge-to-edge clarity. The second focal plane BDX-R2 reticle is illuminated and lays out holdover references for long-range work, with a generous 3.70" - 3.90" eye relief keeping the sight picture comfortable across the magnification range. Field of view runs 5.80 - 34.90 ft @ 100 yds across the power range.

Built around a 30mm main tube finished in matte black anodized aluminum, the Sierra6 is rugged enough for hard field use with fogproof and waterproof sealing. The side focus parallax knob allows quick correction from the firing position, and .25 MOA turrets dial corrections with confidence. The whole scope weighs in at 23.80 oz, making it a solid match for lightweight rifle, shotgun, muzzleloader, and crossbow platforms.
