The AKM's barrel is installed in the forward trunnion and pinned (as opposed to the AK-47, which has a one piece receiver with integral trunnions and a barrel that is screwed-in). The forward barrel trunnion has a non-threaded socket for the barrel and a transverse hole for a pin that secures the barrel in place. The AKM has a barrel with a chrome-lined bore and four right-hand grooves at a 240 mm (1 in 9.45 in) or 31.5 calibers rifling twist rate. In order to maintain strength and durability it employs both longitudinal and latitudinal reinforcing ribs. As a weight-saving measure, the stamped receiver cover is of thinner gauge metal than that of the AK-47. Guide rails that assist the bolt carrier's movement which also incorporates the ejector are installed inside the receiver through spot welding. The receiver housing also features a rigid tubular cross-section support that adds structural strength. A rear stock trunnion and forward barrel trunnion are fastened to the U-shaped receiver using rivets. The AKM's receiver is stamped from a smooth 1.0 mm (0.04 in) sheet of steel, compared with the AK-47 where the receiver was machined from heavier gauge steel. The AK-47's chrome-lined barrel was retained, a common feature of Soviet weapons which resists wear and corrosion, particularly under harsh field conditions and near-universal Eastern Bloc use of corrosively primed ammunition. As a result of these modifications, the AKM's weight was reduced by ≈ 1 kg (2.2 lb), the accuracy during automatic fire was increased and several reliability issues were addressed. Notably, the AK-47's milled steel receiver was replaced by a U-shaped steel stamping. The AKMS (top) compared to an AK-47 (bottom)Ĭompared with the AK-47, the AKM features detail improvements and enhancements that optimized the rifle for mass production some parts and assemblies were conceived using simplified manufacturing methods. The GRAU officially designated the AKM as the 6P1 assault rifle. Despite being replaced in the late 1970s by the AK-74, the AKM is still in service in some Russian Army reserve and second-line units and several east European countries. The bolt carrier rides on the two rails, formed on the side of the receiver, with a significant space between the moving and stationary parts. The gas chamber is located above the barrel. The gas operated action has a large bolt carrier with a permanently attached long stroke gas piston. It is a selective fire, gas operated with a rotating bolt, firing in either semi-automatic or fully automatic, and has a cyclic rate of fire of around 600 rounds per minute (RPM). The AKM is an assault rifle chambered in 7.62×39mm Soviet intermediate cartridge. Like the AK-47, many variants of the AKM exist such as the AKMS, AKML, and AKMP. The AKM maintains the AK-47's wood stock, but has simpler individual parts that are favorable for mass production. It was officially replaced in Soviet frontline service by the AK-74 in the late 1970s, but remains in use worldwide. The production of these rifles was carried out at both the Tula Arms Plant and Izhmash.
Rubber ak 47 bayonet series#
Introduced into service with the Soviet Army in 1959, the AKM is the most prevalent variant of the entire AK series of firearms and it has found widespread use with most member states of the former Warsaw Pact and its African and Asian allies as well as being widely exported and produced in many other countries. It was developed as replacement to AK-47 introduced a decade prior. It is the most ubiquitous rifle of the Kalashnikov rifles. 'Kalashnikov's Automatic Rifle Modernised') is an assault rifle designed by Soviet small arms designer Mikhail Kalashnikov in 1959. Avtomát Kalášnikova modernizírovannyj, lit.
