Barrett Optical Ranging System For Nightforce 5.5-22x Riflescopes 66979 puts the science of long range shooting right in your hands. The Barrett BORS Optical Ranging System is an integratedimage electronic ballistic computer that couples directly to the Nightforce 5.5-22x 50mm and 56mm rifle scopes, acting as the upper rear scope ring. This constantly adapting Barrett ballistic computer accounts for every factor - from environmental data to the angle of your rifle, the Barrett BORS System instantly takes care of the calculations, so you can focus on the task of putting lead on target. The BORS Barrett Optical Ranging System for NightForce Scopes without Zero Stop draws from thousands of tables and taking into account a number of real-time external factors, automatically giving the shooter the exact yardage at which a bullet will hit. This ballistics system from Barrett is like having an army of ballisticians behind every shot.

The BORS measures air temperature, barometric pressure and inclination to calculate the ballistic solution for the specified caliber and cartridge. Eliminates the need to count clicks as the distance is shown on the LCD screen.

Barrett 66979 Integrated Scope Computer fits the Nightforce 5.5-22x NXS. Designed primarily to withstand military operations, BORS is rugged and able to operate with a variety of calibers and rifles. Scope and scope rings not included. This model of Barrett BORS must be used with Barrett Scope Rings.
