Mossberg 500
The Mossberg 500 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, about 11 million 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 ...

Heat Shield
In engineering, a heat shield is a component designed to protect an object or a human operator from being burnt or overheated by dissipating, reflecting, and/or absorbing heat. The term is most often used in reference to exhaust heat management and to systems for dissipating frictional heat. Heat shields are used most commonly in the automotive and aerospace industries. Principles of operation Heat shields protect structures from extreme temperatures and thermal gradients by two primary mechanisms. Thermal insulation and radiative cooling, respectively isolate the underlying structure from high external surface temperatures, while emitting heat outwards through thermal radiation. To achieve good functionality the three attributes required of a heat shield are low thermal conductivity (high thermal resistance), high emissivity, and good thermal stability (refractoriness). Porous ceramics with high emissivity coatings (HECs) are often employed to address these three characteristic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hammerless
A hammerless firearm is a firearm that lacks an exposed hammer (firearm), hammer or hammer spur. Although it may not literally lack a hammer, it lacks an external hammer that the user can manipulate directly. One of the disadvantages of an exposed hammer spur is the tendency for it to get caught on items such as clothing; covering (shrouding or bobbing) the hammer by removing the hammer spur reduces this from occurring. Early hammerless firearms Early caplock firearms, patterned after their flintlock ancestors, had exposed hammers. The conversion was done by replacing the flash pan with a nipple for a percussion cap, and the flintlock's cock with a hammer to crush the metallic cap and ignite the powder. The hammer was on the side of the firearm, which is easily reached for priming and cocking. The earliest cartridge (firearms), cartridge firearms simply copied the older style of action; the Springfield Model 1873 "Trapdoor" rifle and most early cartridge double-barreled shotgu ...

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 ...

New Haven 600
New Haven 600 is a series of pump-action shotguns manufactured by O.F. Mossberg & Sons on behalf of department stores, most notably the Montgomery Ward Company, Western Auto, and other retail stores. ''New Haven'' is one of O.F. Mossberg & Sons' private, promotional brands. The New Haven 600 is identical to the Mossberg 500 from O.F. Mossberg & Sons, with the addition of an anti-rattle system in the magazine tube, and the top of the receiver is not drilled out of a scope mount. Many of the 600AT models came with adjustable C-Lect Chokes.

Forearm (firearm Component)
In firearms, the forearm (also known as the fore-end/forend, handguard or forestock) is a section of a gunstock between the receiver and the muzzle. It is used as a gripping surface to hold the gun steady and is usually made out of heat-insulating material such as wood Wood is a structural tissue/material found as xylem in the stems and roots of trees and other woody plants. It is an organic materiala natural composite of cellulosic fibers that are strong in tension and embedded in a matrix of lignin t ... or reinforced plastic. Near the front of the forearm there is often an underside sling swivel stud and sometimes also a barrel-band to secure the forearm to the barrel (as seen in the photo). Some forearms are equipped with additional heat shields to protect the user from heat radiating from the barrel when the firearm is fired.

Stock (firearms)
A gunstock or often simply stock, the back portion of which is also known as a shoulder stock, a buttstock, or simply a butt, is a part of a long gun that provides structural support, to which the barrel, action, and firing mechanism are attached. The stock also provides a means for the shooter to firmly brace the gun and easily aim with stability by being held against the user's shoulder when shooting the gun, and helps to counter muzzle rise by transmitting recoil straight into the shooter's body. The tiller of a crossbow is functionally the equivalent of the stock on a gun. History and etymology The term stock in reference to firearms dates to 1571 is derived from the Germanic word ''Stock'', meaning tree trunk, referring to the wooden nature of the gunstock. Early hand cannons used a simple stick fitted into a socket in the breech end to provide a handle. The modern gunstock shape began to evolve with the introduction of the arquebus, a matchlock with a longer barrel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shotgun
A shotgun (also known as a scattergun, peppergun, or historically as a fowling piece) is a long gun, long-barreled firearm designed to shoot a straight-walled cartridge (firearms), cartridge known as a shotshell, which discharges numerous small spherical projectiles called shot (pellet), shot, or a single solid projectile called a shotgun slug, slug. Shotguns are most commonly used as smoothbore firearms, meaning that their gun barrels have no rifling on the inner wall, but rifled barrels for shooting Sabot (firearms), sabot slugs (slug barrels) are also available. Shotguns come in a wide variety of calibers and Gauge (firearms), gauges ranging from 5.5 mm (.22 inch) to up to , though the 12-gauge (18.53 mm or 0.729 in) and 20-gauge (15.63 mm or 0.615 in) bores are by far the most common. Almost all are breechloading, and can be single barreled, double-barreled shotgun, double barreled, or in the form of a combination gun. Like rifles, shotguns also ...
