A Khyber Pass Copy is a firearm manufactured by cottage gunsmiths in the Khyber Pass region between Pakistan and Afghanistan. They get their name from the Adam Khel Afridi, who live around the Khyber pass and were historically the most active arms manufacturers on the Frontier. The area has long had a reputation for producing unlicensed, home-made 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 rifles varies widely, ranging from as good as a factory-produced example to dangerously poor.
