A high-tech Texas gun designer has started shipping its first generation shooting system that combines a hunting rifle with a Linux-based scope that takes so much guesswork out of hitting targets a quarter mile away that even novices can do it.
TrackingPoint Xact System consist of the rifle and electronic scope that accounts for distance, temperature and movement before freeing up the trigger to shoot, the company says.
