Sig Sauer Sierra6BDX 2-12x40mm Riflescope BDX-R2 Reticle

The Sig Sauer Sierra6BDX 2-12x40mm riflescope delivers precision shooting capabilities with integrated ballistic data exchange technology. This advanced optic combines traditional magnification with smart rangefinding features that automatically calculate holdover adjustments. Hunters and precision shooters gain a significant advantage through the BDX system's ability to communicate with compatible rangefinders for instant ballistic solutions.

What Makes This Different

The Sierra6BDX stands apart from conventional riflescopes through its integrated BDX (Ballistic Data eXchange) technology that wirelessly connects to Sig Kilo rangefinders. When paired with a compatible rangefinder, the scope automatically illuminates the correct holdover point on the BDX-R2 reticle based on actual range and environmental conditions. This eliminates guesswork and manual calculations that plague traditional long-range shooting setups. The 30mm main tube provides superior light transmission and tracking reliability compared to standard 1-inch tube scopes.

Key Features

• BDX technology wirelessly pairs with Sig Kilo rangefinders for automatic holdover calculations
• 2-12x magnification range with 40mm objective lens for versatility from close to extended range
• Illuminated BDX-R2 reticle with multiple brightness settings for low-light conditions
• 30mm main tube construction delivers enhanced durability and precise tracking
• Black anodized aluminum housing provides corrosion resistance and low-glare finish
• IPX-7 waterproof rating ensures reliable performance in adverse weather
• Compatible with standard 30mm scope rings and Picatinny rail systems

Field performance centers on the scope's ability to deliver first-round hits at extended distances through its smart ballistic system. The 2-12x magnification range handles everything from timber hunting at close range to precision shots beyond 500 yards. Fog-proof nitrogen purging maintains clear optics in temperature extremes, while the illuminated reticle remains visible during dawn and dusk hunting periods when game is most active.
