DFX TECHNOLOGY AK74 / GP25 Avtomat Kalashnikova 1974 is a gas-operated assault rifle designed by Mikhail Kalashnikov, produced by Russian manufacturer IZH. Also known as the small-caliber Kalashnikov assault rifle, it was officially adopted by the Soviet Army in 1974 as the "5.45mm Avtomat Kalashnikova, obraztsa 1974 goda", and is no more than the older AKM, itself a development of the venerable AK47, re-chambered for a new round, with very minor modifications. The most visible modification is the large and effective muzzle brake, which further reduces already moderate recoil of the new round, and improves the controllability of the rifle in the full automatic mode. The rear sight, while being of the same old design, was accordingly recalibrated for the new cartridge with much flatter trajectory. The wooden buttstock was slightly lightened by two oval cuts on both sides. The pistol grip was made from plastic, and the forend initially was made from wood. The stamped steel magazines were replaced by the plastic magazines of the very distinctive red-brown color. 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. Links Manufacturer
