It is the Expanse upper complete with full auto bcg. Not sure if the dust cover, etc can be added? I think I read that it can?

[Lazarus]

What is the expanse? Is that like Colts version of "Sport"models?

 

[MILSURP Collector]

Expanse is their no frills entry level model. Non chrome barrel and you can add the forward assist and dust cover. Don't know about BCG specs
I'd spend a little more and get the 6920 OEM

With no forward assist, does this orifice operate as an exhaust port...I'm confused?

It is set up to install the forward assist if you want, if not leave it as is.

They put a polymer plug in its place held in place with standard forward-assist roll pin.
