Rock island 03

[GBEAR1]

Does anyone know about what Rock Island serial number range were SA barrels being used. Also what date SA barrels? The rifle in question has a 309k receiver and SA 27 barrel. Thanks in advance

Too "early" - I believe they started about 375K and the percentage rose higher with the increased serial number.

I concur with Rick the Librarian. You more likely have a USMC rifle.

Hope this helps. Happy New Year!
