Shaun of the Dead
The following weapons were used in the film Shaun of the Dead:
Winchester Model 1866 "Yellow Boy"
A Winchester Model 1866 "Yellow Boy" rifle with engraving sits upon the rack of "The Winchester" pub and is used by Shaun (Simon Pegg) to kill several zombies before it runs out of ammo. At a few moments David (Dylan Moran), Liz (Kate Ashfield) and Dianne (Lucy Davis) also hold this rifle.
Heckler & Koch G36C
The British troops are armed with Heckler & Koch G36C rifles, most fitted with export model carrying handle with the single 1.5x sight. Some are also fitted with standard G36C carrying handle, and at least one of the G36Cs is fitted with a suppressor. Each has three tac-lights attached to the three Pictanny rails on the foregrip, presumably to dazzle the oncoming zombies.
A Beretta 92FS is seen on the television show after the apocalypse, and in humorously bad FX, a police officer uses it to blow the back of a zombie's head up.
An unknown 12 Gauge Pump Shotgun is used by Enrique Ramirez on the "Zombies from Hell" advertisement.
