How to quickly zero a rifle
During the Basic Carbine Course at @ravenadvisory students learn how to quickly zero their rifles by removing the bolt-carrier group and aligning the image of the target with the sight picture down range. @loftrick77 did this during the last course in Maxton, NC and was only a couple inches off from the bullseye at 25 meters.
