Vulcan V18
The Vulcan V18 is a semi-automatic rifle based on the ArmaLite AR-180, chambered in 5.56×45mm NATO. It was built using a modified carbon fiber AR-15 lower receiver coupled with a modified AR-180 upper receiver formed from heat treated SAE 4130 steel. Standard features of the rifle include an A2-style flash hider, 20” chrome lined barrel with a 1-7” twist, FAL-style hand guard, and polymer side-folding stock. Additionally, it utilizes STANAG magazine A STANAG magazine or NATO magazine is a type of detachable firearm magazine proposed by NATO in October 1980.

Semi-automatic Rifle
A semi-automatic rifle is a type of rifle that fires a single round each time the Trigger (firearms), trigger is pulled while automatically loading the next Cartridge (firearms), cartridge. These rifles were developed Pre-World War II, and were used throughout World War II. Rifles are firearms designed to be fired while held with both hands and braced against the shooter's shoulder for stability. Externally similar shotguns can fire multiple Shot (pellet), pellets simultaneously through a smoothbore, while rifle Gun barrel, barrels are Rifling, rifled to spin-stabilize individual bullets. The actions of semi-automatic rifles use a portion of the fired cartridge's energy to eject the spent casing and load a new round into the Chamber (firearms), chamber, readying the rifle to be fired again. This design differs from manually operated rifles such as Bolt action, bolt-action and Lever action, lever-action rifles, which need to chamber a cartridge manually before firing again, and ...

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 1883 ...

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] |

STANAG Magazine
A STANAG magazine or NATO magazine is a type of detachable firearm magazine proposed by NATO in October 1980. Shortly after NATO's acceptance of the 5.56×45mm NATO rifle cartridge, Draft Standardization Agreement ( STANAG) 4179 was proposed in order to allow NATO members to easily share rifle ammunition and magazines down to the individual soldier level. The U.S. M16 rifle's magazine proportions were proposed for standardization. Many NATO members, but not all, subsequently developed or purchased rifles with the ability to accept this type of magazine. However, the standard was never ratified and remains a "Draft STANAG". Magazines The STANAG magazine concept is only an interface, dimensional and controls (magazine latch, bolt stop, etc.) requirement. Therefore, it not only allows one type of magazine to interface with various weapon systems, but also allows STANAG magazines to be made in various configurations and capacities. The standard capacities of STANAG-compatible mag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
