I picked up a Stevens LA Serial #F08XXXX with a 308 bolt head (came off a 270). I want to convert it to a 223 bolt head. I suspect it is old enough to have the large firing pin? I went to Savage Arms parts finder and typed in the serial number and get a message that the finder does not go back farther than F4XXXXXX. Any help pointing me in right direction is appreciated.
