Which is pretty typical of most zombie movies...you never have enough ammo. Shoot 'em till you run out...then use the machete!
I saw a nice add-on shotgun butt that had several rounds of storage space inside. It looks like that one might have some.
I think that's jsut a sling mount, not a speed feed stock. Besides, if you are bringing a shotgun to a zombie apocalypse, I'd recommend an x-rail.

I'll take the AA12...

Seeing as the AA12 is a post 86 NFA item... no, you won't.
An x-rail just takes a bit of patience to acquire.
Umm...you can still own them...sure..it costs more and is a major hassle, but, can still own one.
Only as a post 86 dealer sample. Which means you need a business, an ffl, additional licenses for the nfa stuff, and a police department as a customer.
Or you could get a license to manufacture machine guns, and license the design.
Yes, technically it is possible.
Yep...and since we are talking about zombies attacking..I think I'll say fuck it to filing for all of that crap, and just raid the nearest national guard armory!
Or...I here these work well!

It's remarkably light on ammo.
