590A1: Convert to 5 Shot Tube

[buckonz]

I have a Mossberg 590A1 shotgun. It shipped with a tube that I believe can hold 9 shells.

If I wanted to convert it to 5 shot capacity, what tube (Mossberg Part#) should I get? If there isn't one, does anyone know what the standard 590A1 tube part# is so I can get that and "plug" it?

Thanks in advance.

If you really want to decrease capacity with a plugged tube (I can't see why anyone would) except for when hunting and the max would be 1 in the pipe and 2 in the mag, at least for waterfowl.
Use the same kind of stick that mossberg supplies with a 500. Nothing more than a dowel that fits in the magtube.
