At 1:12 into Stargate SG1 S9E16, Teal'c is seen firing a weapon more like a weapon of the Tau'ri. But I don't recognize it from earlier missions...He usually uses the Staff Weapon.
What is this weapon?
According to the Internet Movie Firearms Database, it's a Heckler & Koch MP7 (with added sights).
I've seen him use the same P90s the rest of the team uses, but this time they had different gear.
