Karjala28s
Karjala28s refers to a specific model of Kalashnikov-pattern rifle, the RK 62 variant, produced in Finland. The RK 62, itself a derivative of the Soviet AK-47, was adopted by the Finnish Defence Forces in 1962, hence the designation. The "Karjala" designation, meaning "Karelia" in Finnish, is a common naming convention for Finnish firearms, often referring to the region where they were produced or developed. The "28s" likely denotes a specific production batch or a minor variation within the RK 62 family, though official documentation detailing the precise meaning of such sub-designations can be scarce in public domain.
These rifles are chambered in 7.62x39mm, the same cartridge as the original AK-47. Finnish RK 62 rifles
