Sorry - the 16 will never be available from the CMP for the same reason you can't get a 14 - the BATF says that "once a machine gun always a machine gun" and they cannot be "downgraded" to to a semi-auto.
Not true. Replace the automatic sear with a semi-automatic sear and the M4/M16 is legal again.
Unless Obama brings back the "Five Deadly Sins" of an eeeeeevil assault rifle: 1) detachable magazine 2) pistol grip 3) bayonet lug 4) flash supressor 5) folding stock.
Not if I’m president. I’ll have 3/4 of the BATF behind bars doing hard time and M14s/M16s out to law abiding civilians with 2, 1000 rounds of Lake City to each CMP owning M14/M16 citizen.
