MAS-49
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 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. The MAS-49 and MAS-49/56 were replaced ...

Manufacture D'armes De Saint-Étienne
The ''Manufacture d'Armes de Saint-Étienne'', often abbreviated to MAS ("Saint-Étienne Weapons Factory" in English) was a French state-owned weapons manufacturer in the town of Saint-Étienne, Loire. Founded in 1764, it was merged into the French state-owned defense conglomerate GIAT Industries in 2001. History Saint-Étienne was well-known as a center of sword and knife manufacturing beginning in the Middle Ages. In 1665, a Royal Arms Depot was created in Paris to store military weapons made in Saint-Étienne. The ''Manufacture d'Armes de Saint-Étienne'' was created by royal decree in 1764 under the supervision of the General Inspector of the Royal Arms Manufacture of Charleville. 12,000 weapons were being produced each year when the French Revolution The French Revolution ( ) was a period of radical political and societal change in France that began with the Estates General of 1789 and ended with the formation of the French Consulate in coup of 18 Bruma ...

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 ...

Semi-automatic Rifle
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. For comparison, a bolt-action rifle requires the user to cycle the bolt manually before they can fire a second time, and a fully automatic rifle fires continuously until the trigger is released. History The first design of a recoil-operated semi-automatic rifle is attributed to Ferdinand Mannlicher, who unveiled the design in 1885 based on work begun in 1883. Other non-gas operated semi-automatic models were the Model 85 and Mannlicher Models 91, 93 and 95 rifles. The designs were deeply flawed and never made past the conceptual/prototype stage due to issues inherent to the black powder used in their cartridges (based around the Austrian 11×58mmR M/77), such as insufficient velocity and excessive fouling; automatic firearms would only become feasible after smoke ...

Direct Impingement
Direct impingement is a type of gas operation for a firearm that directs gas from a fired cartridge indirectly (through the barrel, through a gas block, and then through a gas tube) into the bolt carrier or slide assembly to cycle the action. Firearms using direct impingement are theoretically lighter, more accurate, and less expensive than firearms using cleaner and cooler gas piston systems. Advantages Firearms featuring a direct impingement design are, in principle, capable of being constructed so as to be slightly lighter than their piston operated counterparts (due to the lack of any additional hardware other than the gas tube, which is required to channel the gas from the barrel back towards the action). Unlike conventional gas-operated firearms, direct impingement does away with a separate gas cylinder, piston, and operating rod assembly. High-pressure gas acts directly upon the bolt and carrier, thereby saving weight, lowering manufacturing costs, and reducing the mass o ...

Iron Sight
Iron sights are a system of physical alignment markers (usually made of metallic material) used as a sighting device to assist the accurate aiming of ranged weapons (such as a firearm, airgun, crossbow or even compound bow), or less commonly as a primitive finder sight for optical telescopes. The earliest sighting device, it relies completely on the viewer's naked eye (mostly under ambient lighting), and is distinctly different to optical sights such as telescopic sights, reflector (reflex) sights, holographic sights and laser sights, which make use of optical manipulation and/or active illumination, as well as the newer optoelectronics, which use digital imaging and even incorporate augmented reality. Iron sights are typically composed of two components mounted perpendicularly above the weapon's bore axis: a rear sight nearer (or ''proximally'') to the shooter's eye, and a front sight farther forward (or ''distally'') near the muzzle. During aiming, the shooter aligns his/ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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 ...
