Hi Mike, I see this is out dated to April 2014. I will provide you with a link supported by Remington Society. Here you will find a conversion and listing chart for your interests. Defer to the society on line to enhance your education within Remington.

Here is the link. It appears you will need more Alphabetic Characters to satisfy the date and year of the manufacture of the weapon. One must disassemble and look for stamped characters. Here is a link for that concern. The next link will demonstrate where to find the code and its definitions. The final piece of information would be the Remington Arms direct link to contact.

Cary Call Remington and give them the serial number, they will tell you when it was born, however keep in mind they due make errors.

What is the barrel code and the serial # letter prefix? I am assuming your second letter in the barrel code is 'Q' based on what you say above 1978 or 1996. If it is a 1978 then the prefix letter in the serial number on the receiver will most likely be 'V'. If it is a 1996 then the prefix letter in the serial number on the receiver will most likely be 'B' or possible 'C' Please always keep in mind that if you bought your gun used or second hand it may have had the barrels swapped and this can cause much confusion.example is a 1996 barrel will fit just fine on a 1978 receiver or vice versa!!!!!

Jaydaddy1 wrote:How can I tell if I have a 78 or 96? In addition to what TuJays said, the barrel date stamps usually take long enough to repeat that you can get a pretty solid idea of which potential date applies to your gun based on its features. For example, in the mid-1980s, Remington implemented some minor design updates to the action on 12ga 870s, including a 'U'-shaped cut-out in the shell carrier that prevented a certain type of malfunction from binding the gun's action.

If your 870 is a 12ga, and you're trying to figure out whether it was made in 1978 or 1996 (which are on opposite sides of the '80s), your shell carrier will give you a strong clue. Other things that help separate 1978 from 1996 are screw-in chokes (introduced in 1986), Express models (1987), and nickel-plated finishes (1992). A decent overview of which models and features were available when can be found. Keep in mind that barrels can be changed, guns can be refinished, and old parts can be replaced with new ones, so these things won't always reflect a specific date with 100% surety. However, if you can identify several features that line up with one of your date possibilities, you should be able to identify the correct one fairly confidently. If you want to be absolutely sure, call or email Remington and have them look up your gun's serial number.

From several different sources, of which Remington is one of them, that tells me it was manufactured in November 1998, 1969, or 1925. 1998.how can that be? It's because you're taking the first two letters from the serial number, and looking them up as if they were a barrel date stamp. These are two different things, but most of the 'guides' online don't explain this very well, if they even try.

Some even call the barrel date stamp a serial number. I've been trying to gather enough information to put together a complete, well-explained guide to dating 870s. I'm close, but I'm having trouble finding help with the last few details. Remington of course just stonewalled me when I tried to email them directly about it. In any case, an 'RS-' serial number points to a manufacture date of 2009/2010 (not sure exactly which) or later.

I'm aware of that change, but I've been unable to determine exactly what year that happened. If anyone can share their serial number prefixes for 870s with confirmed manufacture dates from 2008 - 2011, it would really help me out with this project. Anyway, it's not as if the serial number prefixes were ever all that precise anyway. For the time being at least, 'RS' can simply be considered the successor prefix to 'AB'. And at least Remington seems to have changed the serial number prefixes & suffixes at the same time, so we can easily work out whether or not the serial number suffix is indicating a gun's chambering.
