Want to trade my brand new 21 or 20 inch barrelfor an 18.5" barrel.
Mossbergsays its a 20 but it measures 21 inches. It is blued and new and blued but would trade for any 18.5 that they installed on the 510 Bantam.
Thanks

you might want to verify, but I don't think the 18.5 off of a 510 will fit a 500 or vice versa. The distance from the breach to the barrel nut isn't the same. As a matter of fact, here is the measurement from my 510 so you can check your 500 and see. With the barrel installed, the distance from the front of the receiver to the barrel nut is 9 and 7/8 inches
The limited research I did says they will.
Found out that Mossberg says barrel is a 22" but it measures 21" from where I measured it at.

Limited research aside.....have you measured your barrel from receiver to barrel nut? I suggest you measure your barrel before you possibly waste your time. The 510 mini has a short magazine tube and measures 9 7/8", my 500 measures 14.5" so the barrels won't swap. Unless you have a short tube 500 which I don't think I've ever seen.
I have both guns and the barrels will not interchange on mine.
