LAS VEGAS — An electro-optics targeting system released last year by Sig Sauer has many of the elements that Army, Marine and special operations forces are looking to have in their long-range and advanced optics.

The BDX, or Ballistic Data Xchange, system was on display this week at the company’s range day during the annual Shooting, Hunting and Outdoor Trade Show here.

The system allows shooters a way to adjust their aim point inside the scope with the use of an external range finder and smartphone application. A shooter can work with a spotter who uses the range finder and makes the adjustment or can use the range finder themselves before settling in behind the scope.
