What bayonet fits the Mossberg 590 special purpose??

The same one that fits on a M16/AR15
I got one at a gun show with a sheath for $40.
I know you can get them cheaper online,but I was buying a bunch of other stuff for my AR.

i have seen pics with both an M7 and a M9, both are usually available on ebay. the M9 has the trick wire cutter/sheath in case you barbed wire your house. various manufacturers.
