Rifle
A rifle is a long gun, long-barreled firearm designed for accurate shooting and higher stopping power, with a gun barrel, barrel that has a helical or spiralling pattern of grooves (rifling) cut into the bore wall. In keeping with their focus on accuracy, rifles are typically designed to be held with both hands and braced firmly against the shooter's shoulder via a buttstock for stability during shooting. Rifles are used in warfare, law enforcement, hunting and shooting sports, target shooting sports. The invention of rifling separated such firearms from the earlier smoothbore weapons (e.g., arquebuses, muskets, and other long guns), greatly elevating their accuracy and general effectiveness. The raised areas of a barrel's rifling are called ''lands''; they make contact with and exert torque on the projectile as it moves down the bore, imparting a spin. When the projectile leaves the barrel, this spin persists and lends gyroscopic stability to the projectile due to conservatio ...

Bullpup
A bullpup firearm is one with its firing grip located in front of the Chamber (firearms), breech of the weapon, instead of behind it. This creates a weapon with a shorter overall length for a given barrel length, and one that is often lighter, more compact, concealable, and more maneuverable than a conventionally configured firearm. Where it is desirable for troops to be issued a more compact weapon, the use of a bullpup configuration allows for barrel length to be retained, thus preserving muzzle velocity, range, and ballistic effectiveness. The bullpup concept was first tested militarily in 1901 with the British Thorneycroft carbine, but it was not until the Cold War that more successful designs and improvements led to wider adoption. In 1977, the Austrian Federal Army, Austrian Army became the first military force in the world to adopt a bullpup rifle, the Steyr AUG, as a service rifle, principal combat weapon. Since then the militaries in many countries have followed suit w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bushmaster M17S
The Bushmaster M17S is a semi-automatic bullpup rifle that was manufactured by Bushmaster Firearms International from 1992 until 2005. History The design of the M17S dates back to 1986 when the Australian company Armtech Ltd. developed the prototype as a prospective military rifle for the Australian Army. Two prototypes were developed, one for the 5.56×45mm NATO, the C60R, and the more revolutionary C30R that used caseless ammunition. The C30R was developed hastily and an out-of-battery ignition resulted in a prototype exploding during a high-profile demonstration. The Australian Army adopted a licence-built version of the Steyr AUG, leading to the sale of the Armtech design to another Australian company, Edenpine (Edenpine Pty Ltd. Charles St. George, improved the design, resulting in the ART-30 and SAK-30. The salient features of the M17S were in place but some Finnish Valmet parts were used instead of AR-15 parts to reduce costs. Edenpine expressed interest in selling t ...

Bushmaster Arm Pistol
The Bushmaster Arm Pistol was a 5.56×45mm NATO firearm, categorizeable as either a long pistol (under the American legal definition of a pistol) or compact carbine rifle, produced by the Gwinn Firearms Company, and later Bushmaster Firearms Inc. The firearm was a new design, having a rotating bolt combined with a long stroke gas piston system similar to the AK-47 rifle. Some AR-15 parts were used in its construction and it used STANAG type magazines. Production ceased in 1988 for the pistol variant and 1991 for the rifle following Bushmaster's acquisition by the Quality Products Company the previous year; the company now known as Bushmaster is primarily known for making the more common AR-15 type rifles.

Carbon 15
The Carbon 15 is a family of lightweight, magazine-fed pistols, carbines, and rifles developed by defunct United States weapons manufacturer Professional Ordnance, with the design later picked up by Bushmaster Firearms. Overview The Carbon 15 line is closely based on the Colt AR-15 design. Carbon 15 rifles have carbon fiber upper and lower receivers which are lighter than the standard aluminum and steel construction of AR-15 receivers. Carbon 15 rifles are generally chambered in 5.56×45mm NATO/ .223 Remington, although Bushmaster also produced 9×19mm Parabellum versions of the pistol and carbine. In early 2009, Bushmaster began to include the dust cover and forward assist in their Carbon 15 M4-style rifles.

Bushmaster ACR
The Adaptive Combat Rifle (ACR) (known initially as the Masada) is a modular assault rifle designed by Magpul Industries of Austin, Texas. In late January 2008, Bushmaster Firearms International entered into a licensing agreement with Magpul whereby Bushmaster would take over production, future development, and sales of the Masada. It was then known as the Bushmaster ACR. However, Remington Arms is contracted to manufacture the rifle for the US military and US law enforcement agencies, in which it is known as the Remington ACR. Hence, Remington Arms is responsible for the selective-fire version of the ACR, while Bushmaster Firearms International is responsible for the semi-automatic only version. The Remington ACR was one of the weapons displayed to U.S. Army officials during an invitation-only Industry Day on November 13, 2008. The goal of the Industry Day was to review current carbine technology prior to writing formal requirements for a future replacement for the M4 Car ...

Magpul
Magpul Industries Corporation is an American designer and manufacturer of high-tech polymer and composite firearms accessories like M-LOK. Magpul Industries takes its name from its first product, the MagPul (Magazine Puller), an accessory for the STANAG magazines used by NATO armed forces, which aids users in pulling magazines from pouches. Originally based in Boulder, Colorado, Magpul announced its intention to leave the state in 2013 when a proposed magazine capacity law would cause many of its products to become illegal in Colorado. After passage of the law, Magpul relocated its production facilities to Wyoming and corporate offices to Austin, Texas. Background Magpul Industries was founded in 1999 by Richard M. Fitzpatrick, a Force Recon sergeant with the US Marine Corps. The company has two divisions: Magpul Industries, which manufactures firearms accessories and Magpul Core which was founded in 2008 as Magpul Dynamics. Magpul Core provides firearms training and produc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Twist Rate
Rifling is the term for helical grooves machined into the internal surface of a firearms's barrel for imparting a spin to a projectile to improve its aerodynamic stability and accuracy. It is also the term (as a verb) for creating such grooves. The opposite of rifling is smoothbore. Rifling is measured in ''twist rate'', the distance the rifling takes to complete one full revolution, expressed as a ratio with 1 as its base (e.g., 1:). A shorter distance/lower ratio indicates a faster twist, generating a higher spin rate (and greater projectile stability). The combination of length, weight, and shape of a projectile determines the twist rate needed to gyroscopically stabilize it: barrels intended for short, large-diameter projectiles such as spherical lead balls require a very low twist rate, such as 1 turn in 48 inches (122 cm). Barrels intended for long, small-diameter projectiles, such as the ultra-low-drag 80-grain 0.223 inch bullets (5.2 g, 5.56&nbs ...

Steel
Steel is an alloy of iron and carbon that demonstrates improved mechanical properties compared to the pure form of iron. Due to steel's high Young's modulus, elastic modulus, Yield (engineering), yield strength, Fracture, fracture strength and low raw material cost, steel is one of the most commonly manufactured materials in the world. Steel is used in structures (as concrete Rebar, reinforcing rods), in Bridge, bridges, infrastructure, Tool, tools, Ship, ships, Train, trains, Car, cars, Bicycle, bicycles, Machine, machines, Home appliance, electrical appliances, furniture, and Weapon, weapons. Iron is always the main element in steel, but other elements are used to produce various grades of steel demonstrating altered material, mechanical, and microstructural properties. Stainless steels, for example, typically contain 18% chromium and exhibit improved corrosion and Redox, oxidation resistance versus its carbon steel counterpart. Under atmospheric pressures, steels generally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
