rahtreelimbs - my .308 Win M600 Mohawk is SN 6669356 purchased new in 1974. On the barrel's right side, by the letters " R.E.P." is the letter "N" within a triangle. According to the DOM listing that makes its 'birthday' 1966. Problem is there are all sorts of letters and numbers stamped on the barrel so the question becomes 'which one is which'?
Can anyone tell for sure where the DOM letter would be stamped? Regards, Homesteader.
