Substitute weaponry

Substitute weaponry was the primitive modification to the Daleks' gunstick, which fired bullets instead of energy beams.

History
A group of Daleks whose armament circuits were disabled on Exxilon were forced to use substitute weaponry.

The Third Doctor managed to dismantle one from a destroyed Dalek and convert it into a gun, which was later given to Bellal. (TV: Death to the Daleks)

Behind the scenes
The weapons were created from a Beretta M38 with the flights from two-inch mortar bombs and shot actual pellets.

The props were later used as early props for the original Star Wars movie though this original design appears not have been used on-screen. The mortar fins were re-used on Ponda Baba's custom DL-21 blaster pistol prop (not seen on-screen either). This blaster type with the fins was eventually used on screen for Hoth soldiers in Empire Strikes Back.
