I'm selling off my National ordnance corp. M1 carbine. This is not a universal one, that is the EXACT same as a USGI, the barrel, slide, bolt, stock etc are all USGI parts, the barrel is tapped to blank adapt it but you can't tell from the outside. If you want a Choat fiberglass stock you can have it for another $30.00. Price out the carbines and you know this is cheaper then a Khar arms or USGI.
