The SIG Sauer SIERRA6BDX 3-18x44 Rifle Scope is a premium hunting and precision optic built around SIG Sauer’s BDX Ballistic Data Xchange technology. Designed for hunters and marksmen who want intelligent ballistic holdover support in the field, this 3-18x44mm rifle scope combines a versatile magnification range, 44mm objective lens, 30mm maintube, and BDX-R2 Digital Ballistic Reticle.

This SOSBDX63111 model features SIG Sauer’s BDX-R2 Digital Ballistic Reticle with integrated BDX Ballistic Data Xchange 2.0. When paired with a compatible SIG Sauer BDX-enabled rangefinder, the SIERRA6BDX system can provide an intelligent illuminated holdover point based on distance, ballistics, and environmental data, helping reduce manual holdover guesswork during long-range field use.

Built for demanding hunting conditions, the SIERRA6BDX 3-18x44 uses SIG Sauer’s Advanced HDX 6x Optical System, up to 95% light transmission, waterproof and fog-proof performance, argon purging, LevelPlex digital anti-cant technology, and KinETHIC kinetic energy transfer indicator. With 0.25 MOA adjustments, 60 MOA elevation travel, 60 MOA windage travel, and adjustable parallax, this scope is built for serious rifle setups that require a balance of magnification, portability, and ballistic intelligence.

Ideal For

  • Long-range hunting rifles
  • Precision field rifles
  • Lightweight rifle, shotgun, muzzleloader, and crossbow configurations
  • Shooters using compatible SIG Sauer BDX rangefinders
  • Users wanting an intelligent ballistic holdover rifle scope
  • Hunters wanting a versatile 3-18x44 scope
