M14SE
The M21 Sniper Weapon System (SWS) in the US Army is a national match grade M14 rifle, selected for accuracy, and renamed the M21 rifle. The M21 uses a commercially procured 3–9× variable power telescopic sight, modified for use with the sniper rifle. It is chambered for the 7.62×51mm NATO cartridge. Overview "The use of ''"sharpshooters"'' (or snipers) can be traced in U.S. military history from the time of the Revolutionary War of 1775–1781. Every U.S. military action since that time has required the special talent of such men. After the war sniping became a lost art." From 1955–1956, the United States Army Marksmanship Training Unit undertook a program to "reiterate the lessons learned" from past wars. However, "this program was short-lived because of the lack of understanding and appreciation for the value of a sniper throughout the United States Army. The prevailing military attitude then envisioned any future conflict as nuclear with defeat or victory deci ... [...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.

Designated Marksman Rifle
A designated marksman rifle (DMR) is a modern telescopic sight, scoped high-Accuracy and precision, precision rifle used by infantrymen in the designated marksman (DM) role. It generally fills the engagement effective range, range gap between a service rifle and a dedicated sniper rifle, at around . DMRs, unlike the often bolt-action sniper rifles, are semi-automatic rifle, semi-automatic as these have higher rate of fire, rates of fire and typically larger magazine (firearms), magazine capacities (10, 20, or 30 rounds depending on the firearm and operational requirements) to allow rapid engagement of multiple targets. These rifles have to be effective, in terms of probability of kill, hit rates and terminal ballistics, at application ranges exceeding those of ordinary assault rifles and battle rifles, but do not require the extended-range performance of a dedicated sniper rifle. DMRs need to function as part of squad (and possibly at close quarters) and often share some basic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
M24 Sniper Weapon System
The M24 Sniper Weapon System (SWS) or M24 is the military and police version of the Remington Model 700 rifle, ''M24'' being the model name assigned by the United States Army after adoption as their standard sniper rifle in 1988. The M24 is referred to as a "weapon system" because it consists of not only a rifle, but also a detachable telescopic sight and other accessories. The M24 SWS has the "long action" bolt version of the Remington 700 receiver but is chambered for the 7.62×51mm NATO "short action" cartridge that has an overall length of . The "long action" allows the rifle to be re-configured for dimensionally larger cartridges up to in overall length. The M24 originally came tapped for the Leupold Ultra M3A 10×42mm fixed-power scope, which came with a circle-shaped mil-dot glass-etched reticle. This was later replaced in 1998 by the Leupold Mk 4 LR/T M1 10×40mm fixed-power scope with an elongated-shaped mil-dot wire reticle. The rifle also comes with a detachable Har ...

Fiberglass
Fiberglass (American English) or fibreglass (Commonwealth English) is a common type of fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass cloth. The plastic matrix may be a thermoset polymer matrix—most often based on thermosetting polymers such as epoxy, polyester resin, or vinyl ester resin—or a thermoplastic. Cheaper and more flexible than carbon fiber, it is stronger than many metals by weight, non- magnetic, non-conductive, transparent to electromagnetic radiation, can be molded into complex shapes, and is chemically inert under many circumstances. Applications include aircraft, boats, automobiles, bath tubs and enclosures, swimming pools, hot tubs, septic tanks, water tanks, roofing, pipes, cladding, orthopedic casts, surfboards, and external door skins. Other common names for fiberglass are glass-reinforced plastic (GRP), glass-fiber reinforced plastic (GFRP) or GF ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adjustable Ranging Telescope
Developed and patented by James M. Leatherwood, the Adjustable Ranging Telescope (ART) system combines a range-finding scale inside of a telescopic sight (scope) with an adjustable cam integrated into the scope's mount. This raises or lowers the rear of the sight to compensate for the ballistic rise or fall of the projectile. The cam is preset for a specific cartridge, i.e., the 7.62 mm NATO round. Due to the fact that the range cam is locked to the magnification ring, the range is automatically set, and the ballistic fall of the shot is accounted for. This then allows the shooter to place the optic's aiming point directly on the target. During the Vietnam War, Lieutenant A lieutenant ( , ; abbreviated Lt., Lt, LT, Lieut and similar) is a commissioned officer rank in the armed forces of many nations. The meaning of lieutenant differs in different militaries (see comparative military ranks), but it is often sub ... Leatherwood, who already had the patents for his ART system ...

Bolt-action
Bolt-action is a type of manual firearm action that is operated by ''directly'' manipulating the bolt via a bolt handle, which is most commonly placed on the right-hand side of the weapon (as most users are right-handed). Most bolt-action firearms use a rotating bolt design, where the handle must first be rotated upward to unlock the bolt from the receiver, then pulled back to open the breech and allowing any spent cartridge case to be extracted and ejected. This also cocks the striker within the bolt (either on opening or closing of the bolt depending on the gun design) and engages it against the sear. When the bolt is returned to the forward position, a new cartridge (if available) is pushed out of the magazine and into the barrel chamber, and finally the breech is closed tight by rotating the handle down so the bolt head relocks on the receiver. Bolt-action firearms are generally repeating firearms, but some single-shot breechloaders also use bolt-action design as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

American Revolutionary War
The American Revolutionary War (April 19, 1775 – September 3, 1783), also known as the Revolutionary War or American War of Independence, was a major war of the American Revolution. Widely considered as the war that secured the independence of the United States, fighting began on April 19, 1775, followed by the Lee Resolution on July 2, 1776, and the Declaration of Independence on July 4, 1776. The American Patriots were supported by the Kingdom of France and, to a lesser extent, the Dutch Republic and the Spanish Empire, in a conflict taking place in North America, the Caribbean, and the Atlantic Ocean. Established by royal charter in the 17th and 18th centuries, the American colonies were largely autonomous in domestic affairs and commercially prosperous, trading with Britain and its Caribbean colonies, as well as other European powers via their Caribbean entrepôts. After British victory over the French in the Seven Years' War in 1763, tensions between the motherland and he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sharpshooter
A sharpshooter is one who is highly proficient at firing firearms or other projectile weapons accurately. Military units composed of sharpshooters were important factors in 19th-century combat. Along with "marksman" and "expert", "sharpshooter" is one of the three marksmanship badges awarded by the United States Army and the United States Marine Corps. The United States Navy and the United States Coast Guard use a ribbon with an attached "S" device to note a sharpshooter qualification. History Post-American Revolution (1794–1815) Some of the earliest mentions of rifling and sharpshooting units in the United States originate in the time following the American Revolutionary War and during the War of 1812. The US army abolished rifle units following the war in 1783, but they were later revived under General Anthony Wayne and used in the Battle of Fallen Timbers in 1794.Shock Troops of the Confederacy, Fred L.

Sniper Rifles M40 XM21
A sniper is a military/paramilitary marksman who engages targets from positions of concealment or at distances exceeding the target's detection capabilities. Snipers generally have specialized training and are equipped with high-precision rifles and high-magnification optics, and often also serve as scouts/observers feeding tactical information back to their units or command headquarters. In addition to long-range and high-grade marksmanship, military snipers are trained in a variety of special operation techniques: detection, stalking, target range estimation methods, camouflage, tracking, bushcraft, field craft, infiltration, special reconnaissance and observation, surveillance and target acquisition. Etymology The name "sniper" comes from the verb "to snipe", which originated in the 1770s among soldiers in British India in reference to shooting snipes, a wader that was considered an extremely challenging game bird for hunters due to its alertness, camouflaging color and ...
