Smyth Busters: Can an AR-15 Fire Full Auto With an M16 Carrier?
This "Smyth Busters" episode tackles the common misconception about turning a semi-automatic AR-15 into a full-auto machine gun by simply installing an M16 carrier. Brownells Gun Techs Caleb and Steve explain that while an M16 bolt carrier group has a longer shroud to trip the auto sear, it's insufficient on its own. They clarify that all necessary internal components are required for full-auto function, debunking the myth that adding a few parts is enough to convert an AR-15 into a machine gun. The video also touches on Brownells supplying conversion kits to law enforcement agencies with surplus M16s.
