590M mag to tube fed question

Can the 590M be converted from mag to tube fed? It looks possible but I'm not a shotgun guy so I figured I'd ask here!

I saw the 590M standoff (link below) and was curious because I like the look of it alot but am not sold on it being mag fed.

Any feedback is appreciated! TIA
