870 express 3 inch shells

All 870s will safely fire 3" shells when fitted with a 3" chambered barrel. Guns that were built as 2-3/4" only have a different ejector that may cause fired 3" shells to hang up on the front of the ejection port. Replacing the ejector will fix this; all 870 receivers are the same.

Somewhere along the production rem started to install 3" ejectors even on 2 3/4" wingmasters. Problem is no one knows what serial number it started at including remington. That is why some guys put an express 3" barrel on a old 2 3/4" receiver and it works fine with 3" while others don't because they still have the 2 3/4" egector.

Also some of the very early large frame 870's the ejection port was almost 1/4" shorter

Wingmasters will have M in the serial number to designmate a 3" mag receiver a V is a 2 3/4". There are two express receivers 2 3/4& 3" and 2 3/4- 3 1/2.
Not all of each version is stamped 2 3/4 & 3" some are plain, or stamped express or magnum . On 2 3/4-3 1/2 I have seen plain or stamped super magnum or express super magnum pending the year they were made. There may be other stampings out there also god knows with remington

question... when I went to verify my 870 thru the CFC 1-800 number today, It's a wingmaster and at the end of the serial number is a V and it is indeed a 2 3/4 as stamped on the side.. but they were telling me it should also have an A or B in front of the serial#.... no where near the Sn on receiver or barrel is there either letter.... above the sn on the barrel is a couple of squiggly symbols plus the letter A... but I don't think that is what they are looking for.... any ideas?

They did say call them back if it doesn't have it and they will figure it out... I hope...

All 870 barrels were date coded with a letter. Here is a chart and click the link it will show where. Some receivers had a letter most didnot. I found the barrel was the true date if one in front of the serial number on the receiver it was usually a range of like 5 years. She thinks all should have one and they don't.take care

No problem but I am pretty sure they use the same barrel date codes for all firearms produced in the same year but I am not 100% sure on that. take care
 
There has never been a express model in 12ga only chambered for 2 3/4'' they are all 3'' . going back to the late 70's or early 80's whenever they were conceived.
