Model 500 shotguns with g serial number use a specific magazine tube with a ring system around the external diameter of the magazine tube. They have a letter prefix and then 6 numbers, like this: Alpha comes before bravo, and 100000. My best guess from reading what i could find was it was manufactured in the early 80s.
