C12 pulse rifle
From Tardis Wiki, the free Doctor Who reference
After spending nearly a century stranded on Earth, Commander Brak managed to build himself a C12 pulse rifle in secret and concealed it on his person; he used it to attack a Sontaran envoy who had denied him an honourable execution, goading the other Sontaran into delivering a killing shot with his own rifle.
