I was asking because I bought a used 20 last month and while it had a speed bead syn. stock, it has a 20 3/8" barrel from the receiver to the end of the barrel and I wondered what it was. It reads Remington 870 express Magnum on the receiver. I have since switched the stock to a SureShot, changed the trigger spring and am taking it in to be drilled and tapped for a marlin base this week.
