Sig Sauer Sierra 6 BDX 2 3-18x44mm Riflescope BDX-R2 Reticle

The Sig Sauer Sierra 6 BDX 2 delivers ballistic data exchange technology that automatically calculates range, wind, and environmental factors for precise long-range shooting. This advanced riflescope integrates with Sig's Kilo rangefinder system to provide real-time ballistic solutions directly in the scope's display.

What Makes This Different

The BDX (Ballistic Data Xchange) system sets this scope apart from conventional optics by wirelessly connecting to compatible Sig rangefinders and environmental sensors. When paired with a Kilo rangefinder, the Sierra 6 BDX 2 automatically receives range data and displays precise holdover information on the illuminated BDX-R2 reticle. This eliminates manual calculations and reduces time between target acquisition and shot placement compared to traditional scopes requiring separate ballistic apps or manual adjustments.

Key Features

• 3-18x magnification range with 44mm objective lens for versatile engagement distances
• 30mm main tube construction provides increased adjustment range and light transmission
• BDX-R2 illuminated reticle with automatic ballistic holdover display integration
• Wireless connectivity to Sig Kilo rangefinders for real-time ballistic data
• Low-dispersion glass elements with multiple anti-reflective coatings
• Capped turrets with tactile click adjustments for repeatable tracking
• Black anodized aluminum construction rated for magnum cartridge recoil

Field performance centers on the scope's ability to process environmental data and display accurate holdover points instantly. The system accounts for temperature, barometric pressure, and angle compensation when calculating bullet drop. Hunters benefit from quick target engagement at varying ranges, while precision shooters gain consistent accuracy across different shooting positions and conditions. The scope maintains zero retention through temperature fluctuations and maintains clear glass performance in low-light conditions.
