The Barrett Optical Ranging System (BORS) was an integrated ballistics computer manufactured by Barrett Firearms that aids snipers and long-range marksmen in taking precise and accurate shots. The system mounts directly to the riflescope and couples with the elevation knob. With the aid of the BORS, marksmen can rapidly account for temperature, barometric pressure and aiming at an upward or downward angle.[1]
