Is there any way to buy automag rail blank extrusion

[Pneumagger]

I would like to buy some sort or rail extrusion for an automag. Basically a blank rail with no holes or slots in it.
It would be for my custom marker I'm making so I can do what's needed internally.
I wouldn't mind if it was

I don't know the first place to look for such a thing.
Does AGD have and unmilled extrusions?
