AO-63 Assault Rifle
The AO-63 () is a Soviet two-barrel AK derived assault rifle chambered for the 5.45×39mm round. It was designed by Sergei Simonov and Peter Tkachev, and manufactured by TsNIITochMash. It uses a side-by-side barrel configuration, and it can reach a maximum rate of fire of 6000 rounds/min when fired in two-round burst mode with a 0.01 second delay to increase ballistic performance, making it technically the fastest-firing rifle known. Development The AO-63 assault rifle was used by the Spetsnaz during the Abakan trials in May/June 1986, in search of a more accurate alternative to replace the standard issue AK-74. It was described in the official report as being highly accurate as well as simple and reliable; despite its accuracy and performance, it was later dropped out of the competition for unknown reasons, with the AN-94 emerging victorious. Overview The AO-63 is a gas-operated, 5.45×39mm caliber, twin-barrel assault rifle derived from the Kalashnikov rifle Kalashnikov ...

Sergei Gavrilovich Simonov
Sergei Gavrilovich Simonov (; 4 October 1894 – 6 May 1986) was a Soviet weapons designer who is considered one of the fathers of the modern assault rifle. Mostly known for the Samozaryadnyi karabin Simonova (), 1945 (self-loading carbine of Simonov, 1945), or SKS carbine, he also pioneered the assault and semi-automatic rifle field in the 1920s and 1930s, mostly under the supervision of both Vladimir Fyodorov and Fedor Tokarev. His early work preceded both the M1 Garand (of 1933), and the later M1 Carbine, AK-47, and M16 series. Biography Born in 1894 in Fedotovo (now Melekhovo), Simonov began work in a foundry immediately after completing his elementary school studies. By the end of World War I, after completing a basic technician's course of instruction, he began working on a pioneering automatic rifle designed by Vladimir Grigoryevich Fyodorov, the Fedorov Avtomat. After the Russian Revolution, Simonov continued further at the Moscow Polytechnic Institute, graduating ...

Spetsnaz
SpetsnazThe term is borrowed from rus, спецназ, p=spʲɪtsˈnas; abbreviation for or 'Special Purpose Military Units'; or () are special forces in many post-Soviet states. Historically, this term referred to the Soviet Union's Spetsnaz GRU, special operations units of the GRU (Soviet Union), Main Intelligence Directorate of the Soviet General Staff (GRU). Today it refers to special forces branches and task forces subordinate to ministries including defence, internal affairs, or emergency situations in countries that have inherited their special purpose units from the Chronology of Soviet secret police agencies, now-defunct Soviet security agencies. As ''spetsnaz'' is a Russian term, it is typically associated with the special units of Russia, but other post-Soviet states often refer to their special forces units by the term as well, since these nations also inherited their special purpose units from the now-defunct Soviet security agencies. Etymology The Russia ...

Multiple-barrel Firearms
A multiple-barrel firearm is any type of firearm with more than one gun barrel, usually to increase the rate of fire or probability of kill, hit probability and to reduce barrel erosion or overheating. History Volley gun Multiple-barrel firearms date back to the 14th century, when the first primitive volley guns were developed. They are made with several single-shot gun barrel, barrels assembled together for firing a large number of shots, either simultaneously or in quick succession. These firearms were limited in firepower by the number of barrels bundled, and needed to be manually prepared, ignited, and reloaded after each firing. In practice the large volley guns were not particularly more useful than a cannon firing canister shot or grapeshot. Since they were still mounted on a carriage, they could be as hard to aim and move around as a heavy cannon, and the many barrels took as long (if not longer) to reload.Matthew Sharpe "Nock's Volley Gun: A Fearful Discharge" ''A ...

Assault Rifles Of The Soviet Union
In the terminology of law, an assault is the act of causing physical harm or unwanted physical contact to another person, or, in some legal definitions, the threat or attempt to do so. It is both a crime and a tort and, therefore, may result in criminal prosecution, civil liability, or both. Additionally, assault is a criminal act in which a person intentionally causes fear of physical harm or offensive contact to another person. Assault can be committed with or without a weapon and can range from physical violence to threats of violence. Assault is frequently referred to as an attempt to commit battery, which is the deliberate use of physical force against another person. The deliberate inflicting of fear, apprehension, or terror is another definition of assault that can be found in several legal systems. Depending on the severity of the offense, assault may result in a fine, imprisonment, or even death. Generally, the common law definition is the same in criminal and tort la ...

Kalashnikov Rifle
Kalashnikov rifles (), also known as the AK platform, AK rifles, or simply the AK, are a family of assault rifles based on Mikhail Kalashnikov's original design. They are officially known in Russian as ''avtomat Kalashnikova'' (), and informally as ''kalash'' in Russian. They were originally manufactured in the Soviet Union by Kalashnikov Concern (formerly Izhmash). Rifles similar to the Kalashnikov and its Soviet variants were later produced in many countries friendly to the Soviet Bloc, with rifles based on its design such as the Galil ACE and the INSAS also being produced. The Kalashnikov is one of the most widely used firearm A firearm is any type of gun that uses an explosive charge and is designed to be readily carried and operated by an individual.

Gas-operated
Gas-operation is a system of operation used to provide energy to operate locked breech, Semi-automatic firearm, autoloading firearms. In gas-operation, a portion of high-pressure gas from the Cartridge (firearms), cartridge being fired is used to power a mechanism to dispose of the spent Casing (ammunition), case and insert a new cartridge into the Chamber (firearms), chamber. Energy from the gas is harnessed through either a port in the Gun barrel, barrel or a trap at the Muzzle (firearms), muzzle. This high-pressure gas impinges on a surface such as a piston head to provide motion for unlocking of the Firearm action, action, extraction of the spent case, ejection, cocking of the Hammer (firearm), hammer or striker, chambering of a fresh cartridge, and locking of the action. History The first mention of using a gas piston in a single-shot breech-loading rifle comes from 1856, by the German Edward Lindner who patented his invention in the United States and Britain. In 1866, Eng ...

AN-94
The AN-94 (, GRAU designation 6P33) is a Russian assault rifle. The initials stand for model of 1994, after its chief designer Gennadiy Nikonov, who previously worked on the Nikonov machine gun. The name refers to the Siberian city of Abakan. The AN-94 was designed as a potential replacement to the AK-74 series of rifles currently in service with the Russian Armed Forces. Due to its complex design and expense, it failed to fill its intended role as a replacement for the AK-74, but it is in limited use as a special purpose weapon. The AN-94 has the unique feature of delaying felt recoil for the first two rounds. This increases hit probability in adverse combat conditions. The AN-94 offers a unique two-shot burst function at a stated 1800 rounds per minute, with the second shot firing very close to the first round. This feature is often known as the "hyperburst" mechanism. Design and operation The most conspicuous identifying feature of the AN-94 is its magazine which is ...

AK-74
The AK-74 ( Russian: , tr. ''Avtomat Kalashnikova obraztsa 1974 goda'', lit. 'Kalashnikov assault rifle model 1974') is an assault rifle designed by small arms designer Mikhail Kalashnikov in 1974 as a successor to the AKM. While primarily associated with the Soviet Union, it has been used by many countries since the 1970s. It is chambered for the 5.45×39mm cartridge, which replaced the 7.62×39mm cartridge of Kalashnikov's earlier automatic weapons for the Soviet Armed Forces. The rifle first saw service with Soviet forces in the Soviet–Afghan War from 1979. The head of the Afghan bureau of the Inter-Services Intelligence (ISI), the intelligence agency of Pakistan, claimed that the American Central Intelligence Agency (CIA) paid $5,000 for the first AK-74 captured by the Afghan mujahideen during the war. , most countries of the former Soviet Union use the rifle. Licensed copies were produced in Bulgaria (AK-74, AKS-74 and AKS-74U), and in the former East Germany ...

Burst Mode (weapon)
In automatic firearms, burst mode or burst-fire is a firing mode enabling the shooter to fire a predetermined number of Cartridge (firearms), rounds, usually two or three rounds on hand held weapons to fifty or more rounds on autocannons, with a single pull of the trigger. This firing mode is commonly used in submachine guns and assault rifles. Other types of firearms, such as machine pistols, including the Heckler & Koch VP70 and Beretta 93R also have a burst mode. The burst mode is normally employed as an intermediate fire mode between Semi-automatic firearm, semi-automatic and Automatic firearm, fully automatic, although some firearms lack a "full auto" capability and use a burst mode instead. For instance, the M16 rifle, M16A4 (the standard-issue service rifle of the USMC) has, in addition to the semi-automatic mode, a three-round burst mode, which replaced the fully automatic mode of the previous M16 rifle, M16A1 and M16A3 models. The reason for this replacement was the mas ...

Rate Of Fire
Rate of fire is the frequency at which a specific weapon can fire or launch its projectiles. This can be influenced by several factors, including operator training level, mechanical limitations, ammunition availability, and weapon condition. In modern weaponry, it is usually measured in rounds per minute (RPM or round/min) or rounds per second (RPS or round/s). There are three different measurements for the rate of fire: cyclic, sustained, and rapid. Cyclic is the maximum rate of fire given only mechanical function, not taking into account degradation of function due to heat, wear, or ammunition constraints. Sustained is the maximum efficient rate of fire given the time taken to load the weapon and keep it cool enough to operate. Finally, rapid is the maximum reasonable rate of fire in an emergency when the rate of fire need not be upheld for long periods. Overview For manually operated weapons such as bolt-action rifles or artillery pieces, the rate of fire is governed primarily ...
