M14 Numbers on the side of receiver.
I've got a M1A,M14 rifle and their is no markings on the rear of the reciever. However, their are some numbers on the left side of the reciever where the stock is covering. (31234520). Who is the maker of this receiver?
The barrel has Winchester 7790190-APR-63-35R on the top left side of it. And has the national match marks on it towards the receiver. The stock has the national match, Defense eagle acceptance stamp on the left side and firing proof "P" stamp under the stock.
Whats the probability that this is a true national match rifle?
