Sig Echo Rv50-lrf 2.5-20x50mm Bdx

The SIG SAUER Sig Echo RV50-LRF 2.5-20x50mm BDX is a precision rifle scope engineered for serious long-range shooters who demand reliability in demanding field conditions. Built on SIG SAUER's proven optics platform, this scope serves law enforcement precision teams, military marksmen, and civilian competition shooters who require glass that performs from close quarters to extreme distance. The variable magnification range and integrated ballistic ranging system make it equally at home on a precision rifle as on a tactical platform where versatility cannot be compromised.

This 50mm objective scope delivers superior light transmission and optical clarity across its full 2.5-20x magnification range, critical when engagement windows close quickly or light fades. The integrated BDX (Ballistic Data Xchange) system allows shooters to input real-world environmental data—wind, elevation, temperature, and ammunition characteristics—then calculates precise holdover and windage solutions instantly, eliminating traditional ballistic card guesswork. The 50mm objective and multi-coated glass design maximize edge-to-edge resolution and contrast, while the robust one-piece tube construction withstands the recoil and rough handling inherent to tactical deployment. Weighing 6.63 lbs, the scope maintains optical performance without adding excessive weight to precision platforms.

This optic excels for shooters running .308 Winchester, 6.5 Creedmoor, or similar cartridges where confirmed first-round hit probability justifies premium glass investment. The variable zoom accommodates both 100-yard tactical applications and 1,000-yard+ distance work, making it ideal for precision rifle teams operating across multiple engagement scenarios. Installation requires standard 30mm rings and compatible Picatinny rails; verification with your specific rifle platform and ammunition load is recommended before field deployment to establish baseline accuracy and BDX calibration.
