Is this a normal ASA / Expansion Chamber setup?

Is that an expansion chamber screwed into the ASA?

It is. I label it unusual but I see it occasionally.

That's a cheap remote setup if I've ever seen one

Wild setup. Buddy Really Dislikes forgrips.

I used to shoot a Black Dragun as a teen, such a cheap wanna be E-spyder but damn I thought I was cool. mine was semi auto only but got checked for full auto couple times, actually shot pretty quick with a Egg ontop, only blended every few... haha
