HK 417
The Heckler & Koch HK417 is a battle rifle designed and manufactured by Heckler & Koch. Being the larger caliber version of the Heckler & Koch HK416, and chambered for the 7.62×51mm NATO rifle cartridge, it is intended for use where the penetrative power, stopping power, and range of the 5.56×45mm NATO HK416 would otherwise be insufficient. The HK417 is gas-operated, has a rotating bolt and is capable of selective fire. The HK417 has been adopted for service by a number of armed forces, special forces, and police organizations throughout the world, including the ''Bundeswehr'', United States Joint Special Operations Command, the United States Army, Russian Spetsnaz forces such as FSB Alpha Group, and others. Design and features The HK417 is similar in internal design to the HK416, although the receiver and working parts are enlarged to suit the larger 7.62×51mm cartridge. The bolt is a seven-lug rotating type, which sits in a bolt carrier and operates in a forged alloy rece ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Rifle
A battle rifle is a service rifle chambered to fire a fully powered cartridge. The term "battle rifle" is a retronym created largely out of a need to differentiate automatic rifles chambered for fully powered cartridges from automatic rifles chambered for intermediate cartridges, which were later categorized as assault rifles. Battle rifles were most prominent from the 1940s to the 1970s, when they were used as service rifles. While modern battle rifles largely resemble modern assault rifle designs, which replaced battle rifles in most roles, the term may also describe older military full-power semi-automatic rifles such as the M1 Garand, SVT-40, Gewehr 41, Gewehr 43, Type 4 rifle, Type 4, FN Model 1949, and MAS-49 rifle, MAS-49. History World War I Semi-automatic First examples of semi-automatic fully powered-cartridge rifles used in World War I are the Meunier rifle, Meunier A6, Fusil Automatique Modèle 1917 in 8×50mmR Lebel and the Winchester Model 1910 in .401 Wincheste ...

Special Forces
Special forces or special operations forces (SOF) are military units trained to conduct special operations. NATO has defined special operations as "military activities conducted by specially designated, organized, selected, trained and equipped forces using unconventional techniques and modes of employment". Special forces emerged in the early 20th century, with a significant growth in the field during World War II, when "every major army involved in the fighting" created formations devoted to special operations behind enemy lines. Depending on the country, special forces may perform functions including Airborne forces, airborne operations, counter-insurgency, counter-terrorism, foreign internal defense, Covert operations, covert ops, Direct action (military), direct action, Hostage crises, hostage rescue, high-value targets/Manhunt (military), manhunt, intelligence, surveillance, target acquisition, and reconnaissance, intelligence operations, Mobility (military), mobility o ...

Direct Impingement
Direct impingement is a type of gas operation for a firearm that utilizes gas from a fired cartridge to impart force on 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 with a direct impingement design can, in principle, be constructed lighter than piston-operated designs. Because high-pressure gas acts directly upon the bolt and carrier in a direct impingement system, it does not need a separate gas cylinder, piston, and operating rod assembly of a conventional piston-operated system, only requiring a gas tube to channel gas from the barrel back towards the action. This saves weight, lowers manufacturing costs, and reduces the mass of the operating parts, and thereby the wear on mechanical parts due to movement. By removing the gas piston, the potential amount of moving mass is also lowered, decreas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

M16 Rifle
The M16 (officially Rifle, Caliber 5.56 mm, M16) is a family of assault rifles adapted from the ArmaLite AR-15 rifle for the United States Armed Forces, United States military. The original M16 was a 5.56×45mm NATO, 5.56×45mm automatic rifle with a 20-round magazine. In 1964, the XM16E1 entered US military service as the M16 and in the following year was deployed for jungle warfare operations during the Vietnam War. In 1969, the M16A1 replaced the M14 rifle to become the US military's standard service rifle. The M16A1 incorporated numerous modifications including a bolt-assist ("forward-assist"), chrome-plated bore, protective reinforcement around the magazine release, and revised flash hider. In 1983, the United States Marine Corps, US Marine Corps adopted the M16A2 rifle, and the United States Army, US Army adopted it in 1986.

Colt AR-15
The Colt AR-15 is a product line of magazine-fed, gas-operated, semi auto rifle manufactured by Colt's Manufacturing Company ("Colt") in many configurations. The rifle is a derivative of its predecessor, the lightweight ArmaLite AR-15, an automatic rifle designed by Eugene Stoner and other engineers at ArmaLite in 1956. Colt currently owns the ''AR-15'' trademark and uses it for its line of semi-automatic AR-15 rifles. History Due to financial problems, and limitations in terms of manpower and production capacity, ArmaLite sold the AR-15 design and the AR-15 trademark along with the ArmaLite AR-10 to Colt's Manufacturing Company in 1959. Some of the first sales were of fully automatic Colt AR-15s to the Federation of Malaya and the United Kingdoms in 1959. Colt started selling the semi-automatic version of the M16 rifle as the Colt AR-15 in 1964. The first mass production version was the Colt AR-15 Sporter, in .223 Remington, with a 20-inch barrel, issued with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AR-10
The ArmaLite AR-10 is a 7.62×51mm NATO battle rifle designed by Eugene Stoner in the late 1950s and manufactured by ArmaLite (then a division of the Fairchild (aircraft manufacturer), Fairchild Aircraft Corporation). When first introduced in 1956, the AR-10 used an innovative combination of a straight-line barrel/stock design with Phenol formaldehyde resin#Applications, phenolic composite, a new patent-filed gas-operated bolt and carrier system and forged alloy parts resulting in a small arm significantly easier to control in automatic fire and over lighter than other infantry rifles of the day. Over its production life, the original AR-10 was built in relatively small numbers, with fewer than 10,000 rifles assembled. However, the ArmaLite AR-10 would become the progenitor for a wide range of firearms. In 1957, the basic AR-10 design was rescaled and substantially modified by ArmaLite to accommodate the .223 Remington cartridge, and given the designation ArmaLite AR-15. In 1959, ...

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 th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spetsnaz
SpetsnazThe term is borrowed from rus, спецназ, p=spʲɪtsˈnas; abbreviation for or 'Special Purpose Military Units'; or () are special forces in many post-Soviet states. Historically, this term referred to the Soviet Union's Spetsnaz GRU, special operations units of the GRU (Soviet Union), Main Intelligence Directorate of the Soviet General Staff (GRU). Today it refers to special forces branches and task forces subordinate to ministries including defence, internal affairs, or emergency situations in countries that have inherited their special purpose units from the Chronology of Soviet secret police agencies, now-defunct Soviet security agencies. As ''spetsnaz'' is a Russian term, it is typically associated with the special units of Russia, but other post-Soviet states often refer to their special forces units by the term as well, since these nations also inherited their special purpose units from the now-defunct Soviet security agencies.
