Just looking for thoughts regarding this, in Marcus's Shop there's two Machine Guns (Components are Barrel5, Body3, Mag5, and Stock5, with what looks like the Tediore Material, it's not bright enough for an Atlas, and it matches with the materials on the Assault Shotgun and Repeater on the rack on the side opposite where Marcus stands. To compare the third Machine Gun in the room (Built with Barrel2, Body5, Mag2, and Stock1), has an Atlas Material of I believe Grade 2.

An interesting find I think, what are your words on this? ---Some Person.
