Well, fwiw, this SonsofLiberty supposed Expert Armorer apparently is not up to speed on how to operate a torque wrench properly! Sadly, that would seem to indicate, no one else there does either or his improper use and mistakes would have been caught and corrected during training! Makes you wonder, if they cant even torque a barrel nut on correctly, what else are they doing wrong?
