JMO, but the Army shot itself in the foot in the late sixties and decided now to put a band aid on it. The DoD was so pumped about improving the M16, they just chucked the M14 to Capitan Crunch or moth balled some for thirty + years. Just look around for USGI parts now compared to a year or two ago. Yea, they could start new production on new parts or whole rifles, but they probably won't. Some whiz will come up with a cheaper alternative. Just my thoughts one the matter, no inside scoop.
