The Barrett BORS Optical Ranging Computer is an integrated electronic ballisticimage computer that couples directly to your Leupold Mark IV riflescope, acting as the upper rear scope ring. This Barrett ballistic computer puts science at your fingertips. From environmental factors to the angle of your rifle, the constantly-adapting Barrett BORS System instantly takes care of the data work so you can focus on the task of putting lead on target. The BORS Barrett Optical Ranging System for Leupold Mark 4 draws from thousands of tables and taking into account a number of real-time external factors, automatically giving the shooter the exact yardage at which a bullet will hit. This ballistics system from Barrett is like having an army of ballisticians behind every shot.

The BORS measures air temperature, barometric pressure and inclination to calculate the ballistic solution for the specified caliber and cartridge. Eliminates the need to count clicks as the distance is shown on the LCD screen.
