Ok guys, these threads requesting the date of manufacture are getting a little out of hand and thus we've agreed that we will no longer be dating any rifles with an F or G serial number prefix. This is because these guns aren't that old and the letter prefix itself will give you a relative idea of when the rifle was manufactured. The "dating" service is intended more for dating and documenting the older collectable guns that are no longer in production and were made prior to 1980.
No Letter Prefix = made between 1958-1967
"F" prefix with a serial number lower than F498821 = 1989 thru Nov. 1st, 1995
"F" prefix with a serial number higher than F498821 = Nov. 1st, 1995 through the end of 2002
"G" prefix started in 2003 with the introduction of the AccuTrigger
"H" prefix started in January of 2010
"J" prefix started in late July/early August 2013
