Crazy Horse Rifle
The Crazy Horse rifle or M14SE is a semi-automatic designated marksman rifle based on the M14 rifle. It is chambered for the 7.62×51mm NATO cartridge and is built by Smith Enterprise Inc. Overview The goal of the Crazy Horse rifle project was to offer current military units a reliable and cost-effective modernization program for Squad Designated Marksmen (SDM) using existing M14 rifles in inventory. The Crazy Horse rifle was designed in conjunction with the Picatinny Arsenal and the Army Infantry School. Although the rifle has many "precision" features built in to make it accurate, it is not a sniper rifle and was designed as a battle rifle to fit the needs of the Army's SDM program. The Crazy Horse rifle is built by Smith Enterprise Inc. and is used by various units within the US Military as the M21A5 and the M14SE. The Crazy Horse's metal components are cryogenically treated prior to assembly, which eliminates the need for bedding the stock with fiberglass and steel inser ...

Sniper Rifle
A sniper rifle is a high-precision, long-range rifle. Requirements include accuracy, reliability, mobility, concealment and optics for anti-personnel, anti-materiel and surveillance uses of the military sniper. The modern sniper rifle is a portable shoulder-fired weapon system with a choice between bolt-action or semi-automatic action, fitted with a telescopic sight for extreme accuracy and chambered for a high-ballistic performance centerfire cartridge. History The Whitworth rifle was arguably the first long-range sniper rifle in the world. Designed by Sir Joseph Whitworth, a prominent British engineer, it used barrels with hexagonal polygonal rifling, which meant that the projectile did not have to bite into the rifling grooves as was done with conventional rifling. His rifle was far more accurate than the Pattern 1853 Enfield, which had shown some weaknesses during the recent Crimean War. At trials in 1857, which tested the accuracy and range of both weapons, Whitworth' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

2nd Infantry Division (United States)
The 2nd Infantry Division (2ID, 2nd ID) ("Indianhead") is a formation of the United States Army. Its current primary mission is the pre-emptive defense of South Korea in the event of an invasion from North Korea. There are approximately 17,000 soldiers in the 2nd Infantry Division, with 10,000 of them stationed in South Korea, accounting for about 35% of the United States Forces Korea personnel. The 2nd Infantry Division is unique in that it is the only U.S. Army division that is made up partially of South Korean soldiers, called KATUSAs (Korean Augmentation to the U.S. Army). This program began in 1950 by agreement with the first South Korean president, Syngman Rhee. Some 27,000 KATUSAs served with the U.S. forces at the end of the Korean War. As of May 2006, approximately 1,100 KATUSA soldiers serve with the 2ID. There were also more than 4,748 Dutch soldiers assigned to the division between 1950 and 1954. Denoted the 2nd Infantry Division-ROK/U.S. Combined Division (2ID/RUCD), ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bipod
A bipod is a V-shaped portable attachment that helps support and steady a device, usually a weapon such as a long gun or a mortar. The term comes from the Latin prefix ''bi-'' and Greek root ''pod'', meaning "two" and "foot" respectively. Bipods are designed to support the weight of the weapon's front portion and barrel, and provide significant stability against unwanted side-to-side movements (i.e. canting) while allowing free movements pivoting around the transverse axis ( pitching). Most modern bipods have foldable and/or telescoping legs, and allow some limited movements around the vertical axis ( panning) and even the longitudinal axis ( tilting). A bipod by itself, with only two supporting legs, is not completely stable and needs to be reinforced by at least one more point of support to be steady, especially against the horizontal shearing force from recoils. This third point of support is typically the buttstock that is firmly pushed/braced against the shooter's body, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leupold
Leupold & Stevens, Inc. is an American manufacturer of telescopic sights, red dot sights, binoculars, rangefinders, spotting scopes, and eyewear located in Beaverton, Oregon, United States. The company, started in 1907, is on its fifth generation of family ownership.Leeson, Fred (November 17, 1996). "All in the family". ''The Oregonian''. History Leupold & Stevens was founded by the German immigrant Markus Friedrich (Fred) Leupold and his brother-in-law Adam Voelpel in 1907, under the name Leupold & Voelpel. At the time, the company specialized in the repair of survey equipment. In 1911, Leupold & Voelpel was contracted by John Cyprian (J.C.) Stevens to manufacture a water level recorder he had designed and patented.

Electrical Discharge Machining
Electrical discharge machining (EDM), also known as spark machining, spark eroding, die sinking, wire burning or wire erosion, is a metal fabrication process whereby a desired shape is obtained by using electrical discharges (sparks). Material is removed from the work piece by a series of rapidly recurring current discharges between two electrodes, separated by a dielectric liquid and subject to an electric voltage. One of the electrodes is called the tool-electrode, or simply the or , while the other is called the workpiece-electrode, or . The process depends upon the tool and work piece not making physical contact. When the voltage between the two electrodes is increased, the intensity of the electric field in the volume between the electrodes becomes greater, causing dielectric break down of the liquid, and produces an electric arc. As a result, material is removed from the electrodes. Once the current stops (or is stopped, depending on the type of generator), new liquid di ...

Scope Mount
Scope mounts are used to attach telescopic sights or other types of sights to firearms. The scope sight itself is usually made for only one of two main types of mounts, which can be classified as ''scopes for ring mounts'' (for example a 30 mm tube) or ''scopes for rail mounts'' (like for example the Zeiss rail). Words such as ''mounts'' and ''bases'' are used somewhat loosely, and can refer to several different parts which are either used together or in place of each other as ways to mount optical sights to firearms. When it comes to the interface of the firearm itself, the Picatinny rail is one of the most widespread standard for new firearms as of 2020. While most scopes are made for being mounted either with a ''ring mount'' or a ''rail mount'', some sights have an integral mounting mechanism allowing them to be attached directly to the firearm, like for example an integrated Picatinny mount. In addition, there are many proprietary and brand-specific types of mounts that e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vortex Flash Hider
The Vortex Flash Hider or Vortex Flash Eliminator is a flash suppressor made by Smith Enterprise, Inc. for a variety of different rifles, carbines, machine guns and handguns. History The Vortex Flash Hider was developed in 1984, and a patent was secured in 1995. Sonja Sommers and Ron Smith of SEI developed the Vortex Flash Hider that incorporates a 5-, 10- and 15-degree twisted helix design, which eliminates up to 99% of visible muzzle flash. The Vortex is somewhat reminiscent of the original "three-prong flash hider" found on the original Vietnam-era M16. However, the Vortex is more robust and makes use of four solid tines, which are four equally spaced and angled 6° from a centerline of the body. The Vortex is the only flash suppressor in the world with a helical flute design that breaks up the flash at multiple locations and angles. SEI makes the Vortex for M16s, AR-15s, M14s, Steyr AUGs and certain pistols such as the Heckler & Koch USP Tactical model. AR-15 rifles The Vor ...

Sound Suppressor
A silencer, also known as a sound suppressor, suppressor, or sound moderator, is a muzzle device that reduces the acoustic intensity of the muzzle report (sound of a gunshot) and muzzle rise when a gun (firearm or air gun) is discharged, by modulating the speed and pressure of the propellant gas from the muzzle and hence suppressing the muzzle blast. Like other muzzle devices, a silencer can be a detachable accessory mounted to the muzzle, or an integral part of the barrel. A typical silencer is a metallic (usually stainless steel or titanium) cylinder containing internal sound baffles, with a hollow bore to allow the projectile (bullet) to exit normally. During firing, the bullet flies through the bore with little hindrance, but most of the expanding gas ejecta behind it is retained through a longer and convoluted escape path created by the baffles, prolonging the release time. This slows down the gas and dissipates its kinetic energy into a larger surface area, reduci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Melonite
Melonite is a telluride of nickel; it is a metallic mineral. Its chemical formula is NiTe2. It is opaque and white to reddish-white in color, oxidizing in air to a brown tarnish. It was first described from the Melones and Stanislaus mine in Calaveras County, California in 1866, by Frederick Augustus Genth. Melonite occurs as trigonal crystals, which cleave in a (0001) direction. It has a specific gravity of 7.72 and a hardness of 1–1.5 (very soft).
