On a film crew, an armorer is the person responsible for all the weapons and firearms used during the production. Armorers work with the producer, director and property master to create a list of all the weapons that will be needed. Sometimes the prop master is also the armorer. Often they research the style of weapons used according to the period and the kind of movie. For specialty weapons the armorer consults with the production designer and the prop maker. The armorer is responsible to make sure all weapons are used comply with federal and local laws. For scenes outside the studio, armorers work with police departments to get the necessary permits. To get the weapons they need, armorers may rent or lease them from licensed armories. Many movie armorers also have their own collection of weapons they may use. Armorers explain safe weapons handling to actors and crews making certain all safety rules are met. It is their responsibility to make sure nobody is hurt while weapons are being used.
