AK47 Is Assault Rifle Designed By Mikhail Kalashnikov
AK-47 (Avtomat Kalashnikova stands for 1947, Russia: Автомат Калашникова образца 1947 года) is an assault rifle designed by Mikhail Kalashnikov, produced by Russian arms makers IZhMASh, and is used by many Eastern bloc nations during the Cold War. This rifle was adopted and used as the standard rifle of the Soviet Union in 1947. [2] Compared with the gun used during World War II, the AK-47 has a smaller size, with a shorter range, wearing a bullet with a caliber 7.62 x 39 mm smaller, and have the choice of shot (selective-fire). AK-47 assault rifles, including one ofThe key changes in AKM, as compared to AK, were the introduction of the stamped steel receiver instead of the milled one, and improved trigger/hammer unit, with added hammer release delay device (often incorrectly referred as a rate reducer). Other changes were the redesigned, slightly raised buttstock and the pistol grip, and the addition of the removable muzzle flip compensator. This spoon-like compensator is screwed onto the muzzle and utilized the muzzle blast to reduce muzzle climb during the automatic fire. The compensator could be replaced by the screw-on "PBS-1 noiseless firing device", generally known as a silencer. This silencer requires a special, sub-sonic ammunition with heavier bullets to be used. Another change from AK to AKM was a slightly improved rear sight, with settings from 100 to 1000 (instead of the 800 on AK) meters. Both 800 and 1000 meters, however, are way too optimistic for any practical use, since the effective fire is limited roughly to 300-400 meters, if not less.
In the 1974, Soviet Army officially adopted the 5.45mm ammunition and the appropriately chambered AK-74 assault rifle as its new standard shoulder arm. The AKM, however, was never officially declared obsolete and removed from service, and is still in Russian army stocks. Some non-infantry units of the Russian Army are still armed with 1960s vintage AKM assault rifles. There's also an increasing interest in the 7.62mm weapons since many troops were disappointed by the effectiveness of the 5.45mm ammo during the local conflicts in the 1990s. Some Russian special forces troops (mostly police and Internal Affairs Ministry), currently operating in Chechnya, are using the venerable 7.62mm AKM rifles. the first and remains a rifle of the most widely produced
