M16 / AR-15 Sporter-1
A crate with an M16 assault rifle is seen in the illegal weapon store in "The Waiting Game" (S09E07). The upper receiver seems to be slickside while the lower is slabside, so the exact model is supposed to be an original M16 or, maybe even more likely, a Colt AR-15 Sporter-1.

This rifle looks more like sporterized military rifle than a purpose-build sporter gun. It has a straight stock, so the base rifle was not a Gewehr 1898 or a Karabiner 98k.
