Using barrel codes (such as those listed above) to date the manufacture are reliable on Remington rifles, as the company rarely changed barrels on a customer’s rifle.

Using these barrel codes to date a shotgun is somewhat unreliable, as shotgun barrels are often interchanged at random. One needs to be sure that the barrel is original to the gun before trusting the Barrel Code listing, above.

(*) On 8/9/99, stopped stamping the barrels with the date code. They continued to mark the date code on the end flap of the shipping box. They resumed stamping the date code on the barrel on 10/1/01.
