However an even keener reader notices that despite the sterling record of auto-weapons owners for over fifty years, and despite: registration, police approval, state approval, special taxes, waiting periods, and extensive background checks, in 1986, ownership of newly manufactured automatic weapons was prohibited to civilians
An AR-15 and M-16 sure look alike. The AR can be modified (only cost $45) to be fully auto and that's the only real difference that I know of. There probably are some other military manufacturing mods though.
