I'm pretty certain that the Artillery barrels that were made, and proofed, at the Erfurt plant were shipped to DWM without sights, the rear sight for certain. As you can see from the photo below, it's not possible to screw on an Artillery barrel with rear sight attached as it "overhangs" the receiver.
