Mossberg 590
The Mossberg 500 (M500) is a series of pump action shotguns manufactured by O.F. Mossberg & Sons. The 500 series comprises widely varying models of hammerless repeaters, all of which share the same basic receiver and action, but differ in bore size, barrel length, choke options, magazine capacity, stock and forearm materials. Model numbers included in the 500 series are the 500, 505, 510, 535, and 590. The Revelation 310 and the New Haven 600 were also variations of the 500 series produced by Mossberg under different names. By 2021, 11,000,000 M500s had been produced, making it the most-produced shotgun of all time. History Designed in 1961 by Carl Benson, the Mossberg 500 was created mainly for use by hunters, but quickly found itself in use by law enforcement because of its reliability and low cost. In the 1970s, the M500 was submitted for military use, but failed to meet the MIL-SPEC 3443E protocol, which involves firing 3,000 rounds of shells with no more than two malf ...

Pump Action
Pump action or slide action is a repeating firearm action that is operated manually by moving a sliding handguard on the gun's forestock. When shooting, the sliding forend is pulled rearward to eject any expended cartridge and typically to cock the hammer/ striker, and then pushed forward to load (''chamber'') a new cartridge into the chamber. Most pump-action firearms use an integral tubular magazine, although some do use detachable box magazines. Pump-action is typically associated with shotguns, although it has been used in rifles and other firearms as well. Because the forend is manipulated usually with the support hand, a pump-action gun is much faster than a bolt-action and somewhat faster than a lever-action, as it does not require the trigger hand to be removed from the trigger while reloading. Also because the action is cycled in a linear fashion, it creates less torque that can tilt and throw the gun off aim when repeat-firing rapidly. History The first slide actio ...

Heat Shield
In thermodynamics, heat is defined as the form of energy crossing the boundary of a thermodynamic system by virtue of a temperature difference across the boundary. A thermodynamic system does not ''contain'' heat. Nevertheless, the term is also often used to refer to the thermal energy contained in a system as a component of its internal energy and that is reflected in the temperature of the system. For both uses of the term, heat is a form of energy. An example of formal vs. informal usage may be obtained from the right-hand photo, in which the metal bar is "conducting heat" from its hot end to its cold end, but if the metal bar is considered a thermodynamic system, then the energy flowing within the metal bar is called internal energy, not heat. The hot metal bar is also transferring heat to its surroundings, a correct statement for both the strict and loose meanings of ''heat''. Another example of informal usage is the term '' heat content'', used despite the fact that p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caliber
In guns, particularly firearms, caliber (or calibre; sometimes abbreviated as "cal") is the specified nominal internal diameter of the gun barrel Gauge (firearms) , bore – regardless of how or where the bore is measured and whether the finished bore matches that specification. It is measured in inches or in millimetres, millimeters. In the United States it is expressed in hundredths of an inch; in the United Kingdom in thousandths; and elsewhere in millimeters. For example, a "45 caliber" firearm has a barrel diameter of roughly . Barrel diameters can also be expressed using metric dimensions. For example, a "9 mm pistol" has a barrel diameter of about 9 millimeters. Since metric and US customary units do not convert evenly at this scale, metric conversions of caliber measured in decimal inches are typically approximations of the precise specifications in non-metric units, and vice versa. In a rifling , rifled barrel, the distance is measured between opposing Rifling#C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Benelli M4 Super 90
The Benelli M4 is a semi-automatic shotgun produced by Italian firearm manufacturer Benelli Armi SpA, and the last of the "Benelli Super 90" series of semi-automatic shotguns. The M4 uses a proprietary action design called the "auto-regulating gas-operated" (ARGO) system, which was created specifically for the weapon. The weapon was designed in 1998, and was adopted by the armed forces of Italy, the United States, United Kingdom, among others, and has been used in a variety of conflicts, leading up to the present day. History On May 4, 1998, the United States Army's Armaments Research, Development and Engineering Center (ARDEC) at Picatinny Arsenal, New Jersey issued Solicitation #DAAE30-98-R-0401, requesting submissions for a new 12 gauge semi-automatic combat shotgun for the U.S. military. In response to the request, Benelli Armi SpA of Urbino, Italy designed and built the Benelli M4 Super 90 Combat Shotgun. On August 4, 1998, five samples of the M4 were delivered to Aberdeen ...

Semi-automatic Shotgun
A semi-automatic shotgun is a repeating shotgun with a semi-automatic action, i.e. capable of automatically chambering a new shell after each firing, but requires individual trigger-pull to manually actuate each shot. Semi-automatic shotguns use gas-, blowback or recoil operation to cycle the action, eject the empty shell, and load another round. Many semi-automatic shotguns also provide an optional manual means of operation such as by pump action or a charging handle. Examples Notable semi-automatic shotguns include: *Akdal MKA 1919 * Armsel Striker-12 *Baikal MP-153 *Benelli M1014 *Beretta 1301 * Beretta AL391 *Beretta Xtrema 2 *Browning Auto-5 *Daewoo USAS-12 * Franchi Special Purpose Shotgun 12 *Franchi SPAS-15 *High Standard Model 10 *Ithaca Mag-10 *IWI Tavor TS12 *Mossberg 9200 *Mossberg 930 *Remington Model 1100 *Remington Model 11-87 *Remington Model SP-10 *Saiga-12 ("''Сайга-12''") *Sjögren shotgun * Smith & Wesson Model 1000 *SRM Arms Model 1216 *Vepr-12 * ...

United States Marine Corps
The United States Marine Corps (USMC), also referred to as the United States Marines, is the maritime land force service branch of the United States Armed Forces responsible for conducting expeditionary and amphibious operations through combined arms, implementing its own infantry, artillery, aerial, and special operations forces.

MIL-SPEC
A United States defense standard, often called a military standard, "MIL-STD", "MIL-SPEC", or (informally) "MilSpecs", is used to help achieve standardization objectives by the U.S. Department of Defense. Standardization is beneficial in achieving interoperability, ensuring products meet certain requirements, commonality, reliability, total cost of ownership, compatibility with logistics systems, and similar defense-related objectives. Defense standards are also used by other non-defense government organizations, technical organizations, and industry. This article discusses definitions, history, and usage of defense standards. Related documents, such as defense handbooks and defense specifications, are also addressed. Definition of document types Although the official definitions differentiate between several types of documents, all of these documents go by the general rubric of "military standard", including defense specifications, handbooks, and standards.

List Of Most-produced Firearms
This page lists more than 100 small arms designs which have been produced in numbers exceeding one million since the late 18th century. Many more types have been made in the hundreds of thousands. Many of the firearms on this list are military weapons which were used during both World Wars, so it is unsurprising that they were manufactured in such high numbers. Others are designed for civilian hunting and sport shooting, which generally sell very well in countries such as the U.S. and Canada. Many of those produced have been destroyed, deactivated or fallen into disrepair, but others will have been kept in working order and sold or passed on from one generation to another down the years. In 2018, Small Arms Survey reported that there are over one billion small arms distributed globally, of which 857 million (about 85 percent) are in civilian hands. U.S. civilians alone account for 393 million (about 46 percent) of the worldwide total of civilian held firearms. This amounts to "120. ...
