a few days ago i picked up a new blued mossy 590 w heat shield.
my question is if i can swap barrels with it to get a longer choke compatable bbl for pheasants, clays, and stuff of the sorts,
thanks in advance,
You can do that, but I belive in order to do so you'll need a mossberg 500 barrel ,and a Mossberg 500 magazine tube. Otherwise I don't belivethere is a choked barrel made directly for the 590. The other option is to have your current barrel gunsmithed to take mossberg choke tubes.
Might be worth it to just buy a cheap used Mossy 500 for hunting.
