What does 30R mean on a Winchester GI barrel? Look s like serial # states with 77....made in 1962
I'm passing on it.. Too expensive...Hey I puchased an M1A in Camp Lejeune about 12 years ago. It was built in 98 but it too came with a Winchester Barrel. I did some research on here. I was told by one of the "Gun Professionals" on here that it was a left over barrel from when Winchester suplied barrels for the M14. Im thinking mine was made in 61 or 62. I cant remember. Anyway he said it would be a great barrel since it was ment for the M14 platform that would shoot full auto. I have had it for about 400 rounds and it still shoots great. Good luck.
