It takes data from thousands of tables and accounts for a number of real-time external factors automatically giving the shooter the exact yardage at which a bullet will hit its target. [ 1 ] Since the BORS is mounted directly to the scope and coupled with the elevation knobs, the computer can interact with the scope by simply turning the ...
