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 machine gun to enter service. Operating mechanism Filed for patent in 1892, the M1895's operating mechanism is one of 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 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 round. The potato digger mechanism, in effect, bears some simila ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heavy Machine Gun
A heavy machine gun (HMG) is significantly larger than light, medium or general-purpose machine guns. HMGs are typically too heavy to be man-portable (carried by one person) and require mounting onto a weapons platform to be operably stable or tactically mobile, have more formidable firepower, and generally require a team of personnel for operation and maintenance. There are two generally recognized classes of weapons identified as HMGs. The first are weapons from World War I identified as "heavy" due to the weight and cumbersomeness of the weapons themselves, which prevents infantrymen from transporting on foot, such as the M1917 Browning machine gun. The second are large-caliber ( 12.7×99mm, 12.7×108mm, 14.5×114mm, or larger) machine guns, pioneered by John Browning with the M2 machine gun, designed to provide increased effective range, penetration and destructive power against covers, vehicles, aircraft and light buildings/fortifications beyond the standard-caliber ...

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 1 ...

303 British
The .303 British (designated as the 303 British by the C.I.P. and SAAMI) or 7.7×56mmR, is a calibre rimmed rifle cartridge. The .303 inch bore diameter is measured between rifling lands as is the common practice in Europe which follows the traditional black powder convention. It was first manufactured in Britain as a stop-gap black powder round put into service in December 1888 for the Lee–Metford rifle. From 1891 the cartridge used smokeless powder which had been the intention from the outset, but the decision on which smokeless powder to adopt had been delayed. It was the standard British and Commonwealth military cartridge for rifles and machine guns from 1889 until the 1950s when it was replaced by the 7.62×51mm NATO. Cartridge specifications The .303 British has 3.64 ml (56 grains H2O) cartridge case capacity. The pronounced tapering exterior shape of the case was designed to promote reliable case feeding and extraction in bolt-action rifles and machine guns a ...

30-06 Springfield
The .30-06 Springfield cartridge (pronounced "thirty-aught-six" ), 7.62×63mm in metric notation, and called the .30 Gov't '06 by Winchester, was introduced to the United States Army in 1906 and later standardized; it remained in military use until the late 1970s. The ".30" refers to the caliber of the bullet in inches. The "06" refers to the year the cartridge was adopted, 1906. It replaced the .30-03, 6mm Lee Navy, and .30-40 Krag cartridges. The .30-06 remained the U.S. Army's primary rifle and machine gun cartridge for nearly 50 years before being replaced by the 7.62×51mm NATO and 5.56×45mm NATO, both of which remain in current U.S. and NATO service. It remains a very popular sporting round, with ammunition produced by all major manufacturers. History In the early-1890s, the U.S. military adopted the smokeless powder .30-40 Krag rimmed cartridge. The 1894 version of that cartridge used a round-nose bullet. Around 1901, the U.S. started developing an experimental riml ...

30-40 Krag
The .30-40 Krag (also known as .30 U.S. and .30 Army) was a cartridge developed in the early 1890s to provide the U.S. armed forces with a smokeless powder cartridge suited for use with modern small-bore repeating rifles to be selected in the 1892 small arm trials. Since the cartridge it was replacing was the .45-70 Government, the round was considered ''small-bore'' at the time. The design selected was ultimately the Krag–Jørgensen, formally adopted as the M1892 Springfield. It was also used in M1893 and later Gatling guns. History and development Though the U.S. Navy and Marine Corps had adopted limited numbers of smokeless powder and bolt-action rifles, the .30-40 was the first cartridge adopted by the US Army that was designed from the outset for smokeless powder. It was patterned after .303 British, to which it is very similar geometrically. After a brief experiment with a 230-grain bullet loading, the .30 Army loading was standardized in 1894 using a metal-jacketed ...

7×57mm Mauser
The 7×57mm Mauser (designated as the 7 mm Mauser or 7×57mm by the SAAMI and 7 × 57 by the C.I.P.) is a first-generation smokeless powder rimless bottlenecked rifle cartridge. It was developed by Paul Mauser of the Mauser company in 1892 and adopted as a military cartridge by Spain in 1893.Jim Wilson "A Perfectly Delightful Cartridge: 7×57 mm Mauser" ''American Rifleman'' November 2009 pp.53–55 It was subsequently adopted by several other countries as the standard military cartridge, and although now obsolete as a military cartridge, it remains in widespread international use as a sporting round. The 7×57 Mauser (originally known in Britain as the .275) was a popular stalking cartridge and sporting rifles in this chambering were made by the famous British riflemakers, such as John Rigby, Holland and Holland, Westley Richards and others. British cartridge nomenclature designated caliber in inches, and the cartridge was known as the .275 bore after the measurement o ...

6mm Lee Navy
The 6mm Lee Navy (6×60mmSR), also known as the 6mm U.S.N.Hanson, Jim, ''The 6mm U.S.N. - Ahead Of Its Time'', ''Rifle Magazine'', Vol. 9, No. 1 (January–February 1977), pp. 38-41 or .236 Navy, is an obsolete American rifle cartridge. It was the service cartridge of the United States Navy and Marine Corps from 1895 (replacing the .45-70 Government round) to 1899, when it was replaced by the .30-40 Krag. History and development By 1894, the U.S. Navy desired to adopt a modern small-bore, smokeless powder service cartridge and rifle in keeping with other first-line naval powers for both naval and marine forces.Sampson, W.T., ''Annual Reports of the Navy Department: Report of Chief of Bureau of Ordnance'', Washington, D.C.: U.S. Government Printing Office (1895), pp. 215–218 Naval authorities decided that the new cartridge should be adaptable to both rifles and machine guns.

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 pioneered the development 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. Browni ...

North Yemeni Civil War
The North Yemen Civil War ( ar, ثورة 26 سبتمبر, Thawra 26 Sabtambar, 26 September Revolution) was fought in North Yemen from 1962 to 1970 between partisans of the Mutawakkilite Kingdom and supporters of the Yemen Arab Republic. The war began with a ''coup d'état'' carried out in 1962 by revolutionary republicans led by the army under the command of Abdullah as-Sallal, who dethroned the newly crowned Imam Muhammad al-Badr and declared Yemen a republic under his presidency. The Imam escaped to the Saudi Arabian border where he rallied popular support from northern Shia tribes to retake power, escalating rapidly to a full-scale civil war. On the royalist side, Jordan, Saudi Arabia, and Israel supplied military aid, and Britain gave covert support, while the republicans were supported by Egypt (then formally known as the United Arab Republic) and were supplied warplanes from the Soviet Union.Sandler, Stanley.
