Not only are there counterfeit weapons, but there is counterfeit ammunition as well. Typically they are based on low-powered modern cartridges. .30 bore cartridges are compatible with 7.63×25mm Mauser or 7.62×25mm Tokarev. .32 bore cartridges are compatible with .32 Auto Colt Pistol / 7.65mm Browning (7.65×17mmSR). 12 bore cartridges are 12 gauge (18.5x70mmR) shotgun shells.  44 bore cartridges are compatible with the 7.92×33mm Kurz round for the World War Two era StG 44. Pakistan has a ban on rifles designed to fire military cartridges; the use of the 44 bore cartridge was a loophole in the law until specifically banned in 2012. It was used in AKM copies chambered or modified for it. It was a popular cartridge because it was easy to modify AKMs to fire it but still fed from standard AK magazines. Saquib brand makes 44 bore ammunition. The ammunition used in the Khyber Pass region is often underloaded, being made from a variety of powders or even old film (which contains nitrocellulose, a key component of smokeless powder); Khyber Pass Copy rifles cannot be expected to withstand the pressures generated by modern commercial ammunition. A few collectors have made extremely mild handloaded cartridges for their Khyber Pass rifles and fired them, at substantial personal risk. The packaging and headstamps are often forged versions of quality foreign brands like GECO ("Gustav Genschow & Co."), Golden Tiger (Vympel IIRC), China Sport (NORINCO), MEN ("Metallwerk Elisenhütte Nassau"), and PPU (Prvi Partizan Užice). Local counterfeits have colorful brand-name packaging like Buffalo, Diamond, Double Dragon, Double Star, Federal SKF, Goodluck, Gorilla, and Tiger SBR. The Khyber Arms Company, a local ammunition manufacturer, makes the Expert or X-Pert brand. It uses counterfeit Winchester ammunition packaging with cartridges stamped with fake NORINCO "State Factory 311" headstamps. New casings and bullet jackets are usually copper-washed steel, like Chinese ammunition. The casings are sometimes recycled from scrounged US or NATO military brass casings. 5.56mm NATO cases are cut-down and reshaped to make .30 bore rounds such as 7.63x25mm Mauser or 7.62x25mm Tokarev. 9×19mm Parabellum cases are cut down to make reloaded .380 ACP / 9×17mm Short or 9×18mm Makarov rounds.
