BORS是一种安装在狙击镜上的综合弹道计算机·专门为1000米以上的远程狙击任务设计。

BORS (Barrett Optical Ranging System) 巴雷特光学测距系统

BORS自行测算气压、气温和枪的倾斜角度等数据.狙击手只要把弹药型号输进操作方便的BORS系统，确定好目标距离，调整瞄准镜角度.等待正确射程显示在BORS显示屏上.即可把目标置于瞄准具的“十”字线中心开始精确射击。此外，计算机还能根据首发射击结果.对瞄准仪进行修正。目前，BORS的第一批次型号BlockI.整合了测距仪的BlockII，具有夜视、广角和稳定图像的BlockIII都相继出台。巴雷特公司还计划将BORS系统用于美军“未来单兵战斗系统”(OMW)上。

BORS (Barrett Optical Ranging System) is an integrated electronic ballistic computer that mounts directly on the riflescope and couples with the elevation knob. In other words, it’s like having an army of ballisticians behind every shot. By taking care of all the science, BORS frees the user to focus on the thrill of putting lead on target.

The computer BORS is put into action by simply turning the elevation knob until the LCD displays the target’s range.

Three internal sensors automatically calculate the ballistic solution. BORS compensates for temperature, changes in barometric pressure and aiming on an upward or downward angle. BORS even determines if the rifle is canted. In fact, the only thing this portable mastermind can’t do is pull the trigger.

The BORS kit includes the Barrett Ballistic PC Software and a BORS data cable that allows the user to program custom loads on their personal computer and transfer them directly to their BORS.
