Barrett Bors Ballistic Computer
BORS is an integrated electronic ballistic computer that mounts directly on your rifle scope and couples to the elevation knob. Just turn the elevation knob until the LCD displays the target’s range. The BORS’ three internal sensors will have automatically calculated your ballistic solution. It compensates for aiming up or down, temperature, and barometric pressure changes. It even tells you if the rifle is canted. Place the cross-hair on the target and fire with first-round confidence.
Currently, BORS is dimensioned for and compatible with non-illuminated Leupold Mark IV tactical scopes in 3.5-10, 4.5-14, 6.5-20 and 8.5-25 powers. BORS is available either by itself or factory installed on the 4.5-14 power Leupold. BORS comes preloaded with most popular cartridges. The BORS kit includes the Barrett Ballistic PC Software and the BORS data cable that allows the user to program custom loads on their PC or laptop and transfer them directly to their BORS.
