 A Khyber Pass copy is a firearm manufactured by cottage gunsmiths in the Khyber Pass region between Pakistan and Afghanistan.The area has long had a reputation for producing unlicensed, homemade copies of firearms using whatever materials are available – more often than not, railway rails, scrap motor vehicles, and other scrap metal.The quality of such firearms varies widely, ranging from as good as a factory-produced example to dangerously poor.
