DFX TECHNOLOGY AK47 / GP25 Avtomat Kalashnikova 1947 is a gas-operated assault rifle designed by Mikhail Kalashnikov, produced by Russian manufacturer IZH, and used in many Eastern bloc nations during the Cold War. It was adopted and standardized in 1947. Compared to the autoloading rifles used in World War II, the AK-47 was generally lighter, more compact, with a shorter range, a smaller 7.62 × 39 mm cartridge, and was capable of selective fire. It was one of the first true assault rifles, and remains the most widely used. The AK-47 and its numerous variants and descendents have been produced in greater numbers than any other assault rifle, and it remains in production to this day. The GP-25 Kastyor is an under barrel grenade launcher for the AK-series of assault rifle. They were first seen by the west in 1984 during the Soviet Invasion of Afganistan. The initial version was designated BG-15, and was fitted under the barrel of AK-74 assault rifles. The main production version, the GP-25 has a different sighting system. Development of the weapon began in 1966 at the Sporting and Hunting Arms Central Design and Research Bureau. Development continued into the 1970s, and in 1978 it was accepted into service.
