MAS-40
The MAS-49 is a French semi-automatic rifle that replaced various bolt-action rifles as the French service rifle that was produced from 1949. It was designed and manufactured by the government-owned Manufacture d'armes de Saint-Étienne, MAS arms factory.Huon, Jean; ''Proud Promise—French Semiautomatic Rifles: 1898–1979'', Collector Grade Publications, 1995. . The French Army formal designation of the MAS-49 is ''Fusil semi-automatique 7 mm 5 M. 49'' ("semi-automatic rifle of 7.5mm model 1949"). The initial MAS-49 semi-automatic rifle was produced in limited quantities (20,600 units), whereas the shorter and lighter variant, the MAS-49/56, was mass produced (275,240 units) and issued to all branches of the French military. Overall, the MAS-49 and 49/56 rifles gained the reputation of being accurate, reliable and easy to maintain in adverse environments. All the MAS-49 and 49/56 rifles feature a rail on the left side of their receivers to accommodate a designated rifle scope. ...

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 ...

Box Magazine
A magazine is an ammunition storage and feeding device for a repeating firearm, either integral within the gun (internal/fixed magazine) or externally attached (detachable magazine). The magazine functions by holding several cartridges within itself and sequentially pushing each one into a position where it may be readily loaded into the barrel chamber by the firearm's moving action. The detachable magazine is sometimes colloquially referred to as a " clip", although this is technically inaccurate since a clip is actually an accessory device used to help load ammunition into a magazine. Magazines come in many shapes and sizes, from tubular magazines on lever-action and pump-action firearms that may tandemly hold several rounds, to detachable box and drum magazines for automatic rifles and light machine guns that may hold more than one hundred rounds. Various jurisdictions ban what they define as "high-capacity magazines". Nomenclature With the increased use of semi-autom ...

M1903 Springfield
The M1903 Springfield, officially the United States Rifle, Caliber .30-06, Model 1903, is an American five-round magazine-fed, bolt-action service repeating rifle, used primarily during the first half of the 20th century. The M1903 was first used in combat during the Philippine–American War, and it was officially adopted by the United States as the standard infantry rifle on June 19, 1903, where it saw service in World War I, and was replaced by the faster-firing semi-automatic eight-round M1 Garand starting in 1936. However, the M1903 remained in service as a standard issue infantry rifle during World War II, since the U.S. entered the war without sufficient M1 rifles to arm all troops. It also remained in service as a sniper rifle during World War II, the Korean War, and the Vietnam War. It remains popular as a civilian firearm, historical collector's piece, a competitive shooting rifle, and as a military drill rifle. History Background During the 1898 war with Spain, t ...

Lee–Enfield
The Lee–Enfield or Enfield is a bolt-action, magazine-fed repeating rifle that served as the main firearm of the military forces of the British Empire and Commonwealth during the first half of the 20th century, and was the British Army's standard rifle from its official adoption in 1895 until 1957. The WWI versions are often referred to as the "SMLE", which is short for the common "Short, Magazine, Lee–Enfield" variant. A redesign of the Lee–Metford (adopted by the British Army in 1888), the Lee–Enfield superseded the earlier Martini–Henry, Martini–Enfield, and Lee-Metford rifles. It featured a ten-round box magazine which was loaded with the .303 British cartridge manually from the top, either one round at a time or by means of five-round chargers. The Lee–Enfield was the standard issue weapon to rifle companies of the British Army, colonial armies (such as India and parts of Africa), and other Commonwealth nations in both the First and Second World Wars (suc ...

French Navy
The French Navy (french: Marine nationale, lit=National Navy), informally , is the maritime arm of the French Armed Forces and one of the five military service branches of France. It is among the largest and most powerful naval forces in the world, ranking seventh in combined fleet tonnage and fifth in number of naval vessels. The French Navy is one of eight naval forces currently operating fixed-wing aircraft carriers,Along with the U.S., U.K., China, Russia, Italy, India and Spain with its flagship being the only nuclear-powered aircraft carrier outside the United States Navy, and one of two non-American vessels to use catapults to launch aircraft. Founded in the 17th century, the French Navy is one of the oldest navies still in continual service, with precursors dating back to the Middle Ages. It has taken part in key events in French history, including the Napoleonic Wars and both world wars, and played a critical role in establishing and securing the French colonial ...

Spiral Development
The spiral model is a risk-driven software development process model. Based on the unique risk patterns of a given project, the spiral model guides a team to adopt elements of one or more process models, such as Iterative and incremental development, incremental, Waterfall model, waterfall, or Software_prototyping#Evolutionary_prototyping, evolutionary prototyping. History This model was first described by Barry Boehm in his 1986 paper, "A Spiral Model of Software Development and Enhancement". In 1988 Boehm published a similar paper to a wider audience. These papers introduce a diagram that has been reproduced in many subsequent publications discussing the spiral model. These early papers use the term "process model" to refer to the spiral model as well as to incremental, waterfall, prototyping, and other approaches. However, the spiral model's characteristic risk-driven blending of other process models' features is already present: In later publications, Boehm describes the ...

FAMAS
The FAMAS (''Fusil d'Assaut de la Manufacture d'Armes de Saint-Étienne'', "Assault Rifle from the Saint-Étienne Weapon Factory") is a bullpup assault rifle designed and manufactured in France by MAS in 1978, a year after the Austrian Steyr AUG. It is known by French troops as ''Le Clairon'' (The Bugle) due to its distinctive shape. The FAMAS is recognised for its high rate of fire at 1,100 rounds per minute. Beginning in 2017, the FAMAS was replaced in most frontline units in the French Army by the HK416F, and the FAMAS is expected to remain in limited service until 2028. History The first French bullpup rifles were developed between 1946 and 1950 at the AME (''Atelier Mécanique de Mulhouse'') and MAS, testing rounds such as .30 US Carbine, 7.92×33mm Kurz, 7.65×38mm (Made by ''Cartoucherie de Valence'') and some other intermediate calibers. Since France was engaged in the First Indochina War at the time, and was also the second-largest contributor to NATO, the research ...

Rifle Scope
A telescopic sight, commonly called a scope informally, is an optical sighting device based on a refracting telescope. It is equipped with some form of a referencing pattern – known as a ''reticle'' – mounted in a focally appropriate position in its optical system to provide an accurate point of aim. Telescopic sights are used with all types of systems that require magnification in addition to reliable visual aiming, as opposed to non-magnifying iron sights, reflector (reflex) sights, holographic sights or laser sights, and are most commonly found on long-barrel firearms, particularly rifles, usually via a scope mount. The optical components may be combined with optoelectronics to add night vision or smart device features. History The first experiments directed to give shooters optical aiming aids go back to the early 17th century. For centuries, different optical aiming aids and primitive predecessors of telescopic sights were created that had practical ...

Service Rifle
A service rifle (or standard-issue rifle) is a rifle a military issues to regular infantry. In modern militaries, this is typically a versatile and rugged battle rifle, assault rifle, or carbine suitable for use in nearly all environments. Most militaries also have service pistols or sidearms to accompany their service rifles. History Firearms with rifled barrels existed long before the 19th century but did not become widely used before the end of the American Civil War. Thus, rifles in the early 19th century were for specialist marksmen only, whilst ordinary infantry were issued less accurate smoothbore muskets which had a higher rate of fire, with bore diameters as high as 19 mm (0.75 inch). Early "service rifles" of the 1840s, such as the Prussian Dreyse needle gun (1841) and the Swiss Infanteriegewehr Modell 1842, were technically still muskets. Ordnance rifles were introduced in the 1860s, with the French Chassepot (1866) and the Swiss Peabody ''Gewehr Mode ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bolt-action
Bolt-action is a type of manual firearm action that is operated by ''directly'' manipulating the bolt via a bolt handle, which is most commonly placed on the right-hand side of the weapon (as most users are right-handed). Most bolt-action firearms use a rotating bolt design, where the handle must first be rotated upward to unlock the bolt from the receiver, then pulled back to open the breech and allowing any spent cartridge case to be extracted and ejected. This also cocks the striker within the bolt (either on opening or closing of the bolt depending on the gun design) and engages it against the sear. When the bolt is returned to the forward position, a new cartridge (if available) is pushed out of the magazine and into the barrel chamber, and finally the breech is closed tight by rotating the handle down so the bolt head relocks on the receiver. Bolt-action firearms are generally repeating firearms, but some single-shot breechloaders also use bolt-action design as ...
