The Barrett Optical Ranging System (BORS) is an exciting new development in long range shooting. The integrated electronic ballistic computer couples directly to the rifle telescope acting as the upper rear scope ring.

Barrett Optical Ranging System (BORS)

• Measures air temperature, barometric pressure, and bore line angle
