To me it looks like the standard stock of the M1014 JSSG / Benelli M4 S90.
I just did some research into “converting” the Benelli M4 and what a mess.
There was a run of M4s that had that stock only it didn’t use the collapsible tube and was a fixed stock. I believe the standard stocked M4s have the collapsible tube, but getting a hold of that stock can be pretty expensive. Then I guess you’ll need to get a few more parts to stay compliant. You’d be looking at well over $2000 total for an M1014.
I have to correct myself, it is the standard stock of the M1014 JSSF and the standard stock of the Benelli M4 S90 all over the world except in the US of A;)
