Gas Operation
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 1883 ...

M1 Carbine
The M1 carbine (formally the United States carbine, caliber .30, M1) is a lightweight semi-automatic carbine chambered in the .30 carbine (7.62×33mm) cartridge that was issued to the U.S. military during World War II, the Korean War, and the Vietnam War. The M1 carbine was produced in several variants and was widely used by military, paramilitary, and police forces around the world after World War II, most notably by the armed forces of South Korea and South Vietnam. The M2 carbine is the selective-fire version of the M1 carbine, capable of firing in both semi-automatic and full-automatic. The M3 carbine was an M2 carbine with an active infrared scope system. Despite having a similar name and physical outward appearance, the M1 carbine is not a carbine version of the M1 Garand rifle. On 1 July 1925, the U.S. Army began using the current naming convention where the "M" is the designation for "Model" and the number represents the sequential development of equipment and ...

Gas OPR
Gas is a state of matter that has neither a fixed volume nor a fixed shape and is a compressible fluid. A ''pure gas'' is made up of individual atoms (e.g. a noble gas like neon) or molecules of either a single type of atom ( elements such as oxygen) or from different atoms ( compounds such as carbon dioxide). A ''gas mixture'', such as air, contains a variety of pure gases. What distinguishes gases from liquids and solids is the vast separation of the individual gas particles. This separation can make some gases invisible to the human observer. The gaseous state of matter occurs between the liquid and plasma states, the latter of which provides the upper-temperature boundary for gases. Bounding the lower end of the temperature scale lie degenerative quantum gases which are gaining increasing attention. High-density atomic gases super-cooled to very low temperatures are classified by their statistical behavior as either Bose gases or Fermi gases. For a comprehensive listing of ...

Dissolution Of The Soviet Union
The Soviet Union was formally dissolved as a sovereign state and subject of international law on 26 December 1991 by Declaration No. 142-N of the Soviet of the Republics of the Supreme Soviet of the Soviet Union. Declaration No. 142-Н of the Soviet of the Republics of the Supreme Soviet of the Soviet Union, formally establishing the dissolution of the Soviet Union as a state and subject of international law. It also brought an end to the Soviet Union's federal government and General Secretary (also President) Mikhail Gorbachev's effort to reform the Soviet political and economic system in an attempt to stop a period of political stalemate and economic backslide. The Soviet Union had experienced internal stagnation and ethnic separatism. Although highly centralized until its final years, the country was made up of 15 top-level republics that served as the homelands for different ethnicities. By late 1991, amid a catastrophic political crisis, with several republics al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gewehr 41
The Gewehr 41 , commonly known as the G41(W) or G41(M), denoting the manufacturer ( Walther/ Mauser), are two distinct and different battle rifles manufactured and used by Germany during World War II. The Walther variant of the G41 was far more common and successful in German military service. They were largely superseded by the improved Gewehr 43, which was derived from the G41(W) although both rifles served concurrently until the end of the war. Background While the Germans experimented with semi-automatic rifles as early as 1901, they didn't consider introducing such a weapon until the Soviets began issuing the SVT-40 rifle in large numbers for their troops. German semi-automatic recoil-operated prototypes proved to be too heavy and not meeting military requirements during trials, while their experience with the Mondragón rifle during World War 1, and studies on captured RSC M1917 rifles, both of which had several flaws, left the German High Command skeptical of ga ...

M1895 Colt–Browning Machine Gun
The Colt–Browning M1895, nicknamed "potato digger" because of its unusual operating mechanism, is an air-cooled, belt-fed, gas-operated machine gun that fires from a closed bolt with a cyclic rate of 450 rounds per minute. Based on an 1889 design by John Browning and his brother Matthew S. Browning, it was the first successful gas-operated reloading, gas-operated machine gun to enter service. Operating mechanism Filed for patent in 1892, the M1895's operating mechanism is one of John Browning, John and Matthew S. Browning's early patents for automatic rifles; they had previously been working on lever-action rifles for Winchester such as the Winchester rifle#Model 1886, Winchester 1886. In a typical lever-action design, the operating lever lies under the rear of the gun, typically below the stock, and is hinged near the breech area. It is operated by rotating the lever down and forward, which causes the breechblock to slide rearward away from the barrel and eject the spent rou ...

John Browning
John Moses Browning (January 23, 1855 – November 26, 1926) was an American firearm designer who developed many varieties of military and civilian firearms, cartridges, and gun mechanisms, many of which are still in use around the world. He made his first firearm at age 13 in his father's gun shop and was awarded the first of his 128 firearm patents on October 7, 1879, at the age of 24. He is regarded as one of the most successful firearms designers of the 19th and 20th centuries and a pioneer of modern repeating, semi-automatic, and automatic firearms. Browning influenced nearly all categories of firearms design, especially the autoloading of ammunition. He invented, or made significant improvements to, single-shot, lever-action, and pump-action rifles and shotguns. He developed the first reliable and compact autoloading pistols by inventing the telescoping bolt, then integrating the bolt and barrel shroud into what is known as the pistol slide. Browning's telescoping b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hiram Stevens Maxim
Sir Hiram Stevens Maxim (5 February 1840 – 24 November 1916) was an American-born British inventor best known as the creator of the first automatic machine gun, the Maxim gun. Maxim held patents on numerous mechanical devices such as hair-curling irons, a mousetrap, and steam pumps. Maxim laid claim to inventing the lightbulb. Maxim experimented with powered flight; his large aircraft designs were never successful. Circa 1904 he designed a highly successful amusement ride called the "Captive Flying Machine" to fund his research while generating public interest in flight. Maxim moved from the United States to the United Kingdom at the age of 41, and remained an American citizen until he became a naturalised British citizen in 1899, and received a knighthood in 1901. Birth and early life Maxim was born in Sangerville, Maine on 5 February 1840, into a family of French Huguenot origin. He became an apprentice coachbuilder at the age of 14 and ten years later, took u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
General Purpose Machine Gun
A general-purpose machine gun (GPMG) is an air-cooled, usually belt-fed machine gun that can be adapted flexibly to various tactical roles for light and medium machine guns. A GPMG typically features a quick-change barrel design calibered for various fully powered cartridges such as the 7.62×51mm NATO, 7.62×54mmR, 7.5×54mm French, 7.5×55mm Swiss and 7.92×57mm Mauser, and be configured for mounting to different stabilizing platforms from bipods and tripods to vehicles, aircraft, boats and fortifications, usually as an infantry support weapon or squad automatic weapon. History The general-purpose machine gun (GPMG) originated with the MG 34, designed in 1934 by Heinrich Vollmer of Mauser on the commission of Nazi Germany to circumvent the restrictions on machine guns imposed by the Treaty of Versailles. It was introduced into the Wehrmacht as an entirely new concept in automatic firepower, dubbed the ''Einheitsmaschinengewehr'', meaning "universal machine gun" in ...
