So often we look at firearms parts, barrels especially, and wonder what the letters, numbers, and markings correspond to. Manufacturer? Batch? Date? Testing Proof? Could be anything.
Remington found an easy way to decipher these markings, with a clever twist.
All information on the markings on your firearm can be found in the link below.
BLACK POWDERX is the name of the game with deciphering the manufacturing month on your Remington firearm that was manufactured after 1921. To decipher the year look at the letter to the right of the month letter. These markings and others can be found on the LEFT side of the barrel. On the RIGHT side of the barrel markings that show magniflux, proof mark, and test are found. Knowing that these markings are there tends to give a soft and fuzzy to the life of your firearm. These markings also show if the firearm has been repaired or not and when the repair happened.
Note: While these markings can be trusted, the firearm needs to have the original barrel for the markings to be true to the firearm. Remington states, “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”
