A semi-automatic rifle is an autoloading rifle that fires a single cartridge with each pull of the trigger and uses part of the fired cartridge's energy to eject the case and load another cartridge into the chamber. This is in contrast to bolt-action rifles, which require the user to cycle the bolt manually before they can fire a second time, and fully automatic rifles which fire continuously until the trigger is released.
The AK-74 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 StG 44 is a German assault rifle developed during World War II by Hugo Schmeisser. It is also known by its early designations as the MP 43 and MP 44. The StG 44 was an improvement of an earlier design, the Maschinenkarabiner 42(H).
A semi-automatic firearm, also called a self-loading or autoloading firearm, is a repeating firearm whose action mechanism automatically loads a following round of cartridge into the chamber and prepares it for subsequent firing, but requires the shooter to manually actuate the trigger in order to discharge each shot. Typically, this involves the weapon's action utilizing the excess energy released during the preceding shot to unlock and move the bolt, extracting and ejecting the spent cartridge case from the chamber, re-cocking the firing mechanism, and loading a new cartridge into the firing chamber, all without input from the user. To fire again, however, the user must actively release the trigger, and allow it to "reset", before pulling the trigger again to fire off the next round. As a result, each trigger pull only discharges a single round from a semi-automatic weapon, as opposed to a fully automatic weapon, which will shoot continuously as long as the ammunition is replete and the trigger is kept depressed.
An automatic rifle is a type of autoloading rifle that is capable of fully automatic fire. Automatic rifles are generally select-fire weapons capable of firing in semi-automatic and automatic firing modes. Automatic rifles are distinguished from semi-automatic rifles in their ability to fire more than one shot in succession once the trigger is pulled. Most automatic rifles are further subcategorized as battle rifles or assault rifles.
The AEK-971 is a selective fire 5.45×39mm assault rifle that was developed at the Kovrov Mechanical Plant (KMZ) by chief designer Stanislav Ivanovich Koksharov, also known as Sergey Koksharov, in the late 1970s and 1980s.
The two most common assault rifles in the world are the Soviet AK-47 and the American M16. These Cold War-era rifles have been used in conflicts both large and small since the 1960s. They are used by military, police, security forces, revolutionaries, terrorists, criminals, and civilians alike and will most likely continue to be used for decades to come. As a result, they have been the subject of countless comparisons and endless debate.
The AK-107 is a Russian 5.45×39mm assault rifle developed from the AK-100-series. It features a "balanced" operating system, similar to that used in the AEK-971. In this case, the designation AK does not indicate Avtomat Kalashnikova but Alexandrov/Kalashnikov. The revised designation indicates the incorporation of a new gas system, designed by Youriy Alexandrov, for Kalashnikov-pattern rifles.
The Zastava M70 is a 7.62×39mm assault rifle developed in the Socialist Federal Republic of Yugoslavia by Zastava Arms. The M70 was an unlicensed derivative of the Soviet AK-47. Due to political differences between the Soviet Union and Yugoslavia at the time, namely the latter's refusal to join the Warsaw Pact, Zastava was unable to directly obtain the technical specifications for the AK and opted to reverse engineer the weapon type. Although the M70 was functionally identical to the AK, it had unique in-built features that better enabled it to fire rifle grenades. These included a thicker receiver, a new latch for the dust cover to ensure it would not be jarred loose by a grenade discharge, and a folding grenade sight bracket over the rifle's gas block, which also shut off the gas system when raised.
The Saiga semi-automatic rifles are a family of Russian semi-automatic rifles manufactured by Kalashnikov Concern, which also manufactures the original AK-47 and its variants, Saiga-12 shotguns and Dragunov sniper rifle. Saiga rifles are a sport version of the Kalashnikov rifle, and are marketed for hunting and civilian use. They are sometimes referred to as Saiga Sporters.
An assault rifle is a select fire rifle that uses an intermediate-rifle cartridge and a detachable magazine. Assault rifles were first put into mass production and accepted into widespread service during World War II. The first assault rifle to see major usage was the German StG 44, a development of the earlier Mkb 42. While immediately after World War II, NATO countries were equipped with battle rifles, the development of the M16 rifle during the Vietnam War prompted the adoption of assault rifles by the rest of NATO. By the end of the 20th century, assault rifles had become the standard weapon in most of the world's armies, replacing full-powered rifles and submachine guns in most roles. The two most successful modern assault rifles are the AK-47 and the M16 designs and their derivatives.
The AO-38 is a 5.45×39mm assault rifle and AK derivative designed by Peter Andreevich Tkachev and first to use the Balanced Automatic Recoil System (BARS) to improve stability giving better accuracy over AK-74's. Its derivatives are the AK-107 and AEK-971.
Project Abakan was a Soviet/Russian advanced assault rifle program in rival to the US Advanced Combat Rifle that took place between 1980 and 1994.
Peter Andreevich Tkachev was a Russian weapons engineer for TsNIITochMash. He is known to have worked on and modified various weapons such as the AO-38, AO-46, AO-62 and AO-63 assault rifles as well as developing the Balanced Automatics Recoil System (BARS) used in the AK-107.
The AK-100 family is a series of Kalashnikov rifles, based upon the AK-74M, intended for export sales. The family of rifles offers the AK-74M system, in multiple cartridges and lengths.
Tilting bolt action is a type of locking mechanism often used in self-loading firearms and, rarely, in straight-pull repeating rifles. Essentially, the design consists of a moving bolt driven by some mechanism, most often a piston with gas pressure from the gas port behind the muzzle. The bolt drops down into receiver recess and locks on bolt closing. Tilting the bolt up and down locks-unlocks in the breech. This tilting allows gas pressure in the barrel from firing the gun to lower to safe levels before the cartridge case is ejected.
AVB-7.62 is a battle rifle designed by Anatoly F. Baryshev that is derived from his weapon operating system. It is characterized by significantly reduced recoil.
The Kalashnikov SR-1 is a semi-automatic rifle designed and manufactured by the Kalashnikov Concern. It is based on the AK-107 assault rifle.
