Gene Stoner
Eugene Morrison Stoner (November 22, 1922 – April 24, 1997) was an American firearms designer who is most associated with the development of the ArmaLite AR-15 rifle that was redesigned and modified by Colt's Patent Firearm Company (now known as Colt's Manufacturing Company, LLC) for the United States military as the M16 rifle. Early life Stoner was born in Gosport, Indiana, on November 22, 1922. They moved to Long Beach, California where he graduated from a Long Beach Polytechnical High School. In 1939, after the Depression, there was not enough money for him to attend college so he went to work as a machinist for Vega Aircraft Company, the forerunner of what became Lockheed Airplane Company now Lockheed Martin Corporation. During World War II, he enlisted for Aviation Ordnance in the U.S. Marine Corps and served in the South Pacific and northern China. In the Corps, he had his first experience of working with heavy-caliber automatic weapons as an armourer. The work ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

AR-5
The ArmaLite AR-5 is a lightweight bolt-action takedown rifle chambered for the .22 Hornet cartridge and adopted as the MA-1 aircrew survival rifle by the United States Air Force. It was developed by ArmaLite, a division of Fairchild Engine and Airplane Corporation in 1954. History The U.S. Air Force needed a compact, lightweight, accurate rifle for the new XB-70 manned bomber aircrew's survival kits. Since the M4 and M6 aircrew survival weapons were no longer in manufacture, the Air Force put out a request for a new survival weapon. Shortly after Fairchild established the ArmaLite division in 1954, ArmaLite designed and submitted the AR-5 in response. The Air Force officially adopted the AR-5 as the MA-1 in 1956. Due to the cancellation of the XB-70 fleet, though, the Air Force never received funding to buy more than the original 12 test models. The M4 and M6 aircrew survival weapons already in inventory were judged to be sufficient for existing Air Force needs. However, adop ...

223 Remington
The .223 Remington (designated as the 223 Remington by the SAAMI and 223 Rem by the CIP) is a rimless, bottlenecked rifle cartridge. It was developed in 1957 by Remington Arms and Fairchild Industries for the U.S. Continental Army Command of the United States Army as part of a project to create a small-caliber, high-velocity firearm. The .223 Remington is considered one of the most popular common-use cartridges and is currently used by a wide range of semi-automatic and manual-action rifles as well as handguns. History The development of the cartridge, which eventually became the .223 Remington, was linked to the development of a new lightweight combat rifle. The cartridge and rifle were developed by Fairchild Industries, Remington Arms, and several engineers working toward a goal developed by U.S. Continental Army Command (CONARC). Development began in 1957. A project to create a small-caliber, high-velocity (SCHV) firearm was created. Eugene Stoner of ArmaLite was al ...

Armalite AR-15
The ArmaLite AR-15 is a select-fire, gas-operated, air-cooled, magazine-fed rifle manufactured in the United States between 1959 and 1964. Designed by American gun manufacturer ArmaLite in 1956, it was based on its AR-10 rifle. The ArmaLite AR-15 was designed to be a lightweight rifle and to fire a new high-velocity, lightweight, small-caliber cartridge to allow infantrymen to carry more ammunition. In 1959, ArmaLite sold its rights to the AR-15 to Colt due to financial difficulties and limitations in terms of manpower and production capacity. After modifications (most notably, the charging handle was re-located from under the carrying handle like AR-10 to the rear of the receiver),Kokalis, Peter GRetro AR-15 nodakspud.com Colt rebranded it the Colt 601, however it still carried the Armalite markings due to contractual obligations to Armalite/Fairchild Aircraft Co. Colt marketed the redesigned rifle to various military services around the world and was eventually adopted by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ArmaLite AR-15 SPAR 3240 DEC
ArmaLite, or Armalite, is an American small arms engineering company, formed in the early 1950s, in Hollywood, California. Many of its products, as conceived by chief designer Eugene Stoner, relied on unique foam-filled fiberglass butt/stock furniture, and a composite barrel using a steel liner inside an aluminum sleeve, including the iconic AR15/ M16 family. While the original ArmaLite ceased business in the 1980s, the brand was revived in 1996, by Mark Westrom. Originating as the light firearms division of Fairchild Engine and Airplane Corporation, ArmaLite was formally incorporated in 1954. Stoner's first design, the AR-1 Parasniper (dating from 1952), was relatively unsuccessful. However, in 1956, when ArmaLite competed in a contest for an aircrew survival rifle, its AR-5 and AR-7 designs were put into production and adopted by elements of the US military. The following year, ArmaLite also competed for the contract for a new main US combat rifle, in the NATO standard 7.62 m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

M14 Rifle
The M14 rifle, officially the United States Rifle, Caliber 7.62 mm, M14, is an American selective fire battle rifle chambered for the 7.62×51mm NATO (.308 in) cartridge. It became the standard-issue rifle for the U.S. military in 1959, replacing the M1 Garand rifle in service with the U.S. Army by 1958 and the U.S. Marine Corps by 1965. The M14 was used by the U.S. Army, Navy, and Marine Corps for Basic and Advanced Individual Training (AIT) from the mid-1960s to the early 1970s. The M14 was the last American battle rifle issued in quantity to U.S. military personnel. In 1967, it was officially replaced by the M16 assault rifle, a lighter weapon with a smaller, intermediate cartridge. The M14 rifle remains in limited service across all branches of the U.S. military, with variants used as sniper and designated marksman rifles, accurized competition weapons, and ceremonial weapons by honor guards, color guards, drill teams and ceremonial guards.

Select-fire
Selective fire is the capability of a weapon to be adjusted to fire in semi-automatic, fully automatic, and/or burst mode. The modes are chosen by means of a selector switch, which varies depending on the weapon's design. Some selective-fire weapons have burst fire mechanisms to limit the maximum number of shots fired automatically in this mode. The most common limits are two or three rounds per trigger pull. Fully automatic fire refers to the ability for a weapon to fire continuously until either the feeding mechanism is emptied or the trigger is released. Semi-automatic refers to the ability to fire one round per trigger pull. The presence of selective fire modes on firearms permits more efficient use of rounds to be fired for specific needs, versus having a single mode of operation, such as fully automatic, thereby conserving ammunition while maximizing on-target accuracy and effectiveness. This capability is most commonly found on military weapons of the 20th and 21st centur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AR10 Armalite Vue D'ensemble NoBG
The Aerojet Rocketdyne AR1 is a thrust RP-1/LOX oxidizer-rich staged combustion cycle rocket engine project. The engine was conceived in 2014, and received US government funding to build a prototype engine in 2016. By 2018, the USAF had committed of government funding to develop the engine and build an initial engine prototype, while Aerojet will put of private capital into the project through the prototype build. , there have been no plans to take the AR1 to full production. History Aerojet Rocketdyne proposed in 2014 to "lobby the government to fund an all-new, U.S.-sourced rocket propulsion system." In June 2014, Aerojet initially projected it would cost under per pair of engines, not including the up to estimated development cost to be funded by the government. Later in 2014, the US Congress passed a law requiring the US Air Force to "develop a new propulsion system by 2019 to replace the RD-180 engine" that powers Atlas V used by United Launch Alliance (ULA).

Piston Ring
A piston ring is a metallic split ring that is attached to the outer diameter of a piston in an internal combustion engine or steam engine. The main functions of piston rings in engines are: # Sealing the combustion chamber so that there is minimal loss of gases to the crank case. # Improving heat transfer from the piston to the cylinder wall. # Maintaining the proper quantity of the oil between the piston and the cylinder wall # Regulating engine oil consumption by scraping oil from the cylinder walls back to the sump. Most piston rings are made from cast iron or steel. Design Piston rings are designed to seal the gap between the piston and the cylinder wall. If this gap were too small, thermal expansion of the piston could mean the piston seizes in the cylinder, causing serious damage to the engine. On the other hand, a large gap would cause insufficient sealing of the piston rings against the cylinder walls, resulting in excessive blow-by (combustion gases entering the ...

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 ...

M4 Carbine
The M4 carbine (officially Carbine, Caliber 5.56 mm, M4) is a 5.56×45mm NATO, gas-operated, magazine-fed carbine developed in the United States during the 1980s. It is a shortened version of the M16A2 assault rifle. The M4 is extensively used by the United States Armed Forces, with decisions to largely replace the M16 rifle in United States Army (starting 2010) and United States Marine Corps (USMC) (starting 2016) combat units as the primary infantry weapon and service rifle. The M4 has been adopted by over 60 countries worldwide, and has been described as "one of the defining firearms of the 21st century". Since its adoption in 1994, the M4 has undergone over 90 modifications to improve the weapon's ergonomics and modularity, including: the M4A1, which strengthened the barrel and removed the burst-fire option; the SOPMOD, an accessory kit containing optical attachments; and the underbarrel M203 grenade launcher. In April 2022, the U.S. Army selected the SIG MCX SPEAR ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
