Match Grade
Match grade frequently refers to quality firearm parts and ammunition that are suitable for a competitive match. Sometimes it also refers to other devices and parts that are made with high precision in mind. Description In firearms, the term is used to refer to ammunition and gun parts that are designed and manufactured in such a way that they have a relatively narrow tolerance and high level of accuracy. No standards are defined for its qualification and as such it is more of a relative term. In addition to its use in shooting sports, match grade equipment is often employed by military and law enforcement sharpshooters. Thus, many gun manufacturers use the term "match grade" to describe their products. For instance, the Heckler & Koch Mark 23 weapons system is considered so specifically tooled for combat that it is match grade, one primary reason that the pistol and its components were selected by the United States Special Operations Command (SOCOM) for service.

Shooting Sports
Shooting sports is a group of competitive sport, competitive and recreational sporting activities involving proficiency tests of accuracy, precision and speed in shooting — the art of using ranged weapons, mainly small arms (firearms and airguns, in forms such as handguns, rifles and shotguns) and bow and arrow, bows/crossbows. Shooting sports can be categorized by equipment, shooting distances, shooting target, targets, time limits and degrees of sport of athletics, athleticism involved. Shooting sports may involve both team and individual competition, and team performance is usually assessed by summing the scores of the individual team members. Due to the noise of shooting and the high (and often lethal) impact (mechanics), impact energy of the projectiles, shooting sports are typically conducted at either designated permanent shooting ranges or temporary shooting fields in the area away from settlements.

Firearm
A firearm is any type of gun designed to be readily carried and used by an individual. The term is legally defined further in different countries (see Legal definitions). The first firearms originated in 10th-century China, when bamboo tubes containing gunpowder and pellet projectiles were mounted on spears to make the portable fire lance, operable by a single person, which was later used effectively as a shock weapon in the Siege of De'an in 1132. In the 13th century, fire lance barrels were replaced with metal tubes and transformed into the metal-barreled hand cannon. The technology gradually spread throughout Eurasia during the 14th century. Older firearms typically used black powder as a propellant, but modern firearms use smokeless powder or other propellants. Most modern firearms (with the notable exception of smoothbore shotguns) have rifled barrels to impart spin to the projectile for improved flight stability. Modern firearms can be described by their caliber ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ammunition
Ammunition (informally ammo) is the material fired, scattered, dropped, or detonated from any weapon or weapon system. Ammunition is both expendable weapons (e.g., bombs, missiles, grenades, land mines) and the component parts of other weapons that create the effect on a target (e.g., bullets and warheads). The purpose of ammunition is to project a force against a selected target to have an effect (usually, but not always, lethal). An example of ammunition is the firearm cartridge, which includes all components required to deliver the weapon effect in a single package. Until the 20th century, black powder was the most common propellant used but has now been replaced in nearly all cases by modern compounds. Ammunition comes in a great range of sizes and types and is often designed to work only in specific weapons systems. However, there are internationally recognized standards for certain ammunition types (e.g., 5.56×45mm NATO) that enable their use across different weapo ...

Engineering Tolerance
Engineering tolerance is the permissible limit or limits of variation in: # a physical dimension; # a measured value or physical property of a material, manufactured object, system, or service; # other measured values (such as temperature, humidity, etc.); # in engineering and safety, a physical distance or space (tolerance), as in a truck (lorry), train or boat under a bridge as well as a train in a tunnel (see structure gauge and loading gauge); # in mechanical engineering, the space between a bolt and a nut or a hole, etc. Dimensions, properties, or conditions may have some variation without significantly affecting functioning of systems, machines, structures, etc. A variation beyond the tolerance (for example, a temperature that is too hot or too cold) is said to be noncompliant, rejected, or exceeding the tolerance. Considerations when setting tolerances A primary concern is to determine how wide the tolerances may be without affecting other factors or the outcome of a ...

Sharpshooters
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.

Heckler & Koch Mark 23
The Heckler & Koch MK 23, MK 23 MOD 0, Mark 23, or USSOCOM MARK 23 is a semi-automatic large-frame pistol chambered in .45 ACP, designed specifically to be an offensive pistol. The USSOCOM version of the MK23 came paired with a laser aiming module (LAM) and suppressor. The USSOCOM MK23 was adopted by the United States Special Operations Command (USSOCOM) for special operations units, beating out the nearest competitor, Colt's OHWS. Development of the pistol began in 1991 as special operations representatives identified the need for an "Offensive Handgun Weapons System—Special Operations Peculiar", and delivery of the pistols began in May 1996 to the special operation units. While the USSOCOM MK23 designation usually applies to the complete system, it is also commonly used in reference to the pistol component alone. The LAM and suppressor were developed by Insight Technology and Knight's Armament Company (KAC), respectively. The civilian version of the Mk23 sold by itself is des ...

United States Special Operations Command
The United States Special Operations Command (USSOCOM or SOCOM) is the unified combatant command charged with overseeing the various special operations component commands of the Army, Marine Corps, Navy, and Air Force of the United States Armed Forces. The command is part of the Department of Defense and is the only unified combatant command created by an Act of Congress. USSOCOM is headquartered at MacDill Air Force Base in Tampa, Florida. The idea of an American unified special operations command had its origins in the aftermath of Operation Eagle Claw, the disastrous attempted rescue of hostages at the American embassy in Iran in 1980. The ensuing investigation, chaired by Admiral James L. Holloway III, the retired Chief of Naval Operations, cited lack of command and control and inter-service coordination as significant factors in the failure of the mission. Since its activation on 16 April 1987, U.S. Special Operations Command has participated in many operations, fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Glossary Of Firearms Terminology
The following are terms related to firearms and ammunition topics. A *Accurize, accurizing: The process of altering a stock firearm to improve its accuracy. *Action: The physical mechanism that manipulates cartridges and/or seals the breech. The term refers to the method in which cartridges are loaded, locked, and extracted from the mechanism. Actions are generally categorized by the type of mechanism used. A firearm action is technically not present on muzzleloaders as all loading is done by hand. The mechanism that fires a muzzleloader is called the lock. *Adjustable sight: Iron sights that allow the user to change the markings, intended for firing at multiple possible ranges. *Ammunition or ammo: Gunpowder and artillery. Since the design of the cartridge, the meaning has been transferred to the assembly of a projectile and its propellant in a single package. * Assault rifle: A service rifle capable of semi- or full automatic fire, that fires intermediate cartridges. *Assau ...
