Markings of Exported Chinese M14 Type Rifles
Early U. S. import Polytech Industries and Norinco manufacturer and model markings are marked on the receiver heel. Heel markings have been observed on Polytech Industries M14/S rifles with serial numbers as high as 028XX. Serial numbers of Chinese M14 rifles are usually stamped above the stock line on the scope mount side, below and slightly behind the rear sight elevation knob. A typical Chinese export M14 is Norinco serial number 9914. The serial number is stamped on the left hand side of the receiver and electro penciled on the left receiver leg. There are no other markings on the receiver. The importer markings, Century Arms in this case, are stamped on the barrel. A very few Norinco rifles imported into the United States have no manufacturer stamping whatsoever. Norinco M14 type rifle model numbers are M-14, M14 Sporter and M305. Some Norinco M14 type rifles have the marking CJA SFLD MICH on the side of the receiver. This marking has been found on Norinco M14 type rifles imported into both the United States and Canada. The Polytech Industries model number is denoted M14S or M14/S. Polytech Industries rifles have a better reputation for receiver surface machining and finish as compared to the Norinco stamped rifles.
The following serial numbers have been observed on Norinco and Polytech Industries M14 type rifles in the United States:
Norinco M-14, M14 Sporter - 00006 to 960XX for Century Arms International imports with some receivers having a letter C prefix, e.g., C08610.
Polytech Industries M14/S, M14S - 00001 to 25### for KFS and CJA/IDE imports and C-1245 for Century Arms International imports
