I concur with the other comments that it’s some kind of custom job (although it doesn’t have to be Khyber Pass specifically, Iraqi & Syrian gunsmiths do cool stuff as well) - the gas tube is way too short, the handguard’s a bit shorter too, there’s… something going on with the rear sight, and the magazine looks off as well (although I’m not sure if it’s 7.62x25 exactly, maybe 8mm Kurz? Dunno)
