No. None were.
The 1934 NFA makes the matter (unconstitutionally) complicated. ALL M-14 rifles were originally select fire. Therefore, they were and always are (by the unconstitutional NFA 1934) machine guns. Selling them to We the People, as was done with the M1, M1903, and some other weapons would require (unconstitutionally) registering them with the BATF, payment of a transfer tax, etc.
Until the unconstitutional 1986, 1968, and 1934 acts of Congress are discarded and sanity returns, we won't see surplus M2, M14, M16, M4 etc being sold by the CMP.
Thanks. I understood they would have required the tax stamp and wondered if any were.
The trouble now is the “in common use” caveat in the recent SCOTS decisions. The select fire rifles are not in common use only because they are banned. If surplus M-14 and M-16 rifles could be had, they would certainly be in common use.
