Leave nothing to chance.

This constantly adapting ballistics computer puts science at your fingertips. From environmental factors to the angle of your rifle, BORS instantly takes care of the data work so you can focus on the task of putting lead on target.

The Barrett Optical Ranging System (BORS) is an integrated ballistics computer that mounts directly on the riflescope and couples to the elevation knob. drawing from thousands of tables and taking into account a number of real-time external factors, it automatically gives the shooter the exact yardage at which a bullet will hit. In other words, it’s like having an army of ballisticians behind every shot.

Once the distance to the target has been estimated, the computer can be put into action by simply turning the elevation knob until the LCD displays the target’s range.

BORS

Three internal sensors automatically calculate the ballistic solution. BORS compensates for temperature, change in barometric pressure and aiming at an upward or downward angle. BORS even determines if the rifle is canted.

The BORS kit includes the proprietary Barrett Ballistic Software* that’s pre-programmed with a library selected by Barrett. It also includes a BORS data cable that allows the user to program custom loads on a personal computer and transfer them directly to BORS.

Designed primarily to withstand military operations, BORS is rugged and able to operate with a variety of calibers and rifles.
