Barrett BORS (Barrett Optical Ranging System) is an integrated electronic ballistic computer that mounts directly on the riflescope and couples with the elevation knob. The BORS measures air temperature, barometric pressure, and bore line angle. It can be adjusted manually for different cartridges/loads and can eleminate the need for "counting clicks". The Barret BORS system allows the shooter to return to tactical concerns. The computer on the Barrett BORS is put into action by simply turning the elevation knob until the LCD displays the target’s range.
Barrett BORS even determines if the rifle is canted. In fact, the only thing this portable mastermind can’t do is pull the trigger.
The Barrett BORS kit includes the Barrett Ballistic PC Software and a Barrett BORS data cable that allows the user to program custom loads on their personal computer and transfer them directly to their Barrett BORS.
