But the M-16 is chambered in 5.56×45mm NATO and is a fully automatic sub-machinegun but the puny (in comparison) AR-15 is chambered in 223/5.56mm NATO (almost a 22L rifle) and is a semi-automatic (one bullet with a single pull of the trigger).
The Washington Post Devil is in the details that make a vast difference.
Any rifle modified beyond the original specs is no longer an AR-15. So there's that.
