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 Leupold Mark 4® rifle telescope acting as the upper rear scope ring.

• 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
• Allows the shooter to focus on environmental conditions, assess the tactical situation, and quickly engage multiple targets at varying ranges
• Takes the mystery out of bullet drop

Leupold Mark IV 3.5-10x40mm LR/T M1
