RPK Machine Gun
The RPK (russian: Ручной пулемёт Калашникова/РПК, Ruchnoy Pulemyot Kalashnikova, link=no, English: "Kalashnikov hand-held machine gun"), sometimes retroactively termed the RPK-47, is a Soviet 7.62×39mm light machine gun that was developed by Mikhail Kalashnikov in the early 1960s, in parallel with the AKM assault rifle. It was created to standardize the small arms inventory of the Soviet Army, where it replaced the 7.62×39mm RPD light machine gun. The RPK continues to be used by the armed forces of countries of the former Soviet Union and certain African and Asian nations. The RPK is also manufactured in Bulgaria, Romania and Serbia. Design details Operating mechanism The RPK functions identically to the AK-47. It also uses the same 7.62×39mm ammunition. It has a similar design layout to the Kalashnikov series of rifles, with modifications to increase the RPK's effective range and accuracy, enhance its sustained fire capability, and strengthen ...

Bipod
A bipod is a V-shaped portable attachment that helps support and steady a device, usually a weapon such as a long gun or a mortar. The term comes from the Latin prefix ''bi-'' and Greek root ''pod'', meaning "two" and "foot" respectively. Bipods are designed to support the weight of the weapon's front portion and barrel, and provide significant stability against unwanted side-to-side movements (i.e. canting) while allowing free movements pivoting around the transverse axis ( pitching). Most modern bipods have foldable and/or telescoping legs, and allow some limited movements around the vertical axis ( panning) and even the longitudinal axis ( tilting). A bipod by itself, with only two supporting legs, is not completely stable and needs to be reinforced by at least one more point of support to be steady, especially against the horizontal shearing force from recoils. This third point of support is typically the buttstock that is firmly pushed/braced against the shooter's body, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oxford University Press
Oxford University Press (OUP) is the university press of the University of Oxford. It is the largest university press in the world, and its printing history dates back to the 1480s. Having been officially granted the legal right to print books by decree in 1586, it is the second oldest university press after Cambridge University Press. It is a department of the University of Oxford and is governed by a group of 15 academics known as the Delegates of the Press, who are appointed by the vice-chancellor of the University of Oxford. The Delegates of the Press are led by the Secretary to the Delegates, who serves as OUP's chief executive and as its major representative on other university bodies. Oxford University Press has had a similar governance structure since the 17th century. The press is located on Walton Street, Oxford, opposite Somerville College, in the inner suburb of Jericho. For the last 500 years, OUP has primarily focused on the publication of pedagogical texts and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rotating Bolt
Rotating bolt is a method of locking the breech (or rear barrel) of a firearm closed for firing. Johann Nicolaus von Dreyse developed the first rotating bolt firearm, the "Dreyse needle gun", in 1836. The Dreyse locked using the bolt handle rather than lugs on the bolt head like the Mauser M 98 or M16. The first rotating bolt rifle with two lugs on the bolt head was the Lebel Model 1886 rifle. The concept has been implemented on most firearms chambered for high powered cartridges since the 20th century. Design Ferdinand Ritter von Mannlicher, who had earlier developed a non-rotating bolt straight-pull rifle, developed the Steyr-Mannlicher M1895, a straight-pull rifle with a rotating bolt, which was issued to the Austro-Hungarian Army. Mannlicher then developed the M1893 auto rifle which had a screw delayed bolt and later the Mannlicher M1900 operated by a gas piston. This was an inspiration for later gas operated, semi-automatic and selective fire firearms (such as the M1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gas-operated Reloading
Gas-operation is a system of operation used to provide energy to operate locked breech, autoloading firearms. In gas-operation, a portion of high-pressure gas from the cartridge being fired is used to power a mechanism to dispose of the spent case and insert a new cartridge into the chamber. Energy from the gas is harnessed through either a port in the barrel or a trap at the muzzle. This high-pressure gas impinges on a surface such as a piston head to provide motion for unlocking of the action, extraction of the spent case, ejection, cocking of the 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, Englishman William Curtis filed the first patent on a gas-operated repeating rifle, but subsequently failed to develop that idea further. Between 18 ...

Mikhail Kalashnikov
Mikhail Timofeyevich Kalashnikov ( rus, Михаи́л Тимофе́евич Кала́шников, p=kɐˈlaʂnʲɪkəf; 10 November 1919 – 23 December 2013) was a Soviet and Russian lieutenant general, inventor, military engineer, writer, and small arms designer. He is most famous for developing the AK-47 assault rifle and its improvements, the AKM and AK-74, as well as the PK machine gun and RPK light machine gun. Kalashnikov was, according to himself, a self-taught tinkerer who combined innate mechanical skills with the study of weaponry to design arms that achieved battlefield ubiquity. Even though Kalashnikov felt sorrow at the weapons' uncontrolled distribution, he took pride in his inventions and in their reputation for reliability, emphasizing that his rifle is "a weapon of defense" and "not a weapon for offense". Early life Kalashnikov was born in the village of Kurya, in present-day Altai Krai, Russia, as the seventeenth child of the 19 children of Aleksandra F ...

War In Donbas (2014–2022)
The War in Donbas, russian: Война на Донбассе was an armed conflict in the Donbas region of Ukraine, part of the broader Russo-Ukrainian War. In March 2014, immediately following the Euromaidan protest movement and subsequent Revolution of Dignity, protests by pro-Russian, anti-government separatist groups arose in the Donetsk and Luhansk oblasts of Ukraine, collectively called the Donbas. These demonstrations began around the same time as Russia's annexation of Crimea, and were part of wider pro-Russian protests across southern and eastern Ukraine. Declaring the Donetsk and Luhansk People's Republics (DPR and LPR, respectively), armed Russian-backed separatist groups seized government buildings throughout the Donbas, leading to armed conflict with Ukrainian government forces. Ukraine launched a military counter-offensive against pro-Russian forces in April 2014, called the "Anti-Terrorist Operation" (ATO) from 2014 until it was renamed the "Joint Forces ...

War In Iraq (2013–2017)
The War in Iraq was an armed conflict between Iraq and its allies and the Islamic State (also known as ISIS or ISIL) which began in 2013 and ended in December 2017. Following December 2013, the insurgency escalated into full-scale guerrilla warfare following clashes in the cities of Ramadi and Fallujah in parts of western Iraq, and culminated in the Islamic State offensive into Iraq in June 2014, which lead to the capture of the cities of Mosul, Tikrit and other cities in western and northern Iraq by the Islamic State. Between 4–9 June 2014, the city of Mosul was attacked and later fell; following this, Prime Minister Nuri al-Maliki called for a national state of emergency on 10 June. However, despite the security crisis, Iraq's parliament did not allow Maliki to declare a state of emergency; many legislators boycotted the session because they opposed expanding the prime minister's powers. Ali Ghaidan, a former military commander in Mosul, accused al-Maliki of being the one ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
