Regarding Chinese parts for the M14 at SEI
At SEI, we repair our M14s with USGI replacement parts.
The Chinese parts we have are take-offs from Polytech and Norinco's that were legally brought into the U.S. in the 1980's.
We can supply those take-off parts to those who want to keep their rifles with orginal parts. Please contact us to check inventory and for another other needs.
