Tranquillizer Weapon

A tranquillizer gun (also spelled tranquilizer gun or tranquilliser gun), capture gun, or dart gun, is a non-lethal gun used for capture via a special chemical.[1] Tranquillizer guns shoot darts filled with tranquillizer that, when injected, temporarily sedates an animal, so that it may be handled (or captured) safely. The tranquillizer can be a sedative, anaesthetic,[2] or paralytic agent. Tranquillizer guns have a long history of use for capturing wildlife without injury. Tranquillizer darts can also be fired by crossbow or breath-powered blowgun.
