Overview

The Barrett Optical Ranging System (BORS) is an exciting new development in long range shooting. The integrated electronic ballistic computer couples directly to the rifle telescope acting as the upper rear scope ring.

Barrett Optical Ranging System (BORS)

• Measures air temperature, barometric pressure, and bore line angle
• Calculates a ballistic solution for a specific user-selected cartridge
• Eliminates the need for "counting clicks", calculating mil dots as target ranges change, or using a handheld computer

• Takes the mystery out of bullet drop
