Breaching Round
A breaching round or slug-shot is a shotgun shell specially made for door breaching. It is typically fired at a range of 6 inches (15 cm) or less, aimed at the hinges or the area between the doorknob and lock and doorjamb, and is designed to destroy the object it hits and then disperse into a relatively harmless powder. Design and construction Breaching rounds are designed to destroy door deadbolts, locks, and hinges without risking lives by ricocheting or by flying on at lethal speed through the door, as traditional buckshot can. These frangible rounds are made of a dense sintered material, often metal powder in a binder such as wax, which can destroy a lock or hinge and then immediately disperse. They are used by military and SWAT teams to quickly force entry into a locked room. Amongst police, these rounds are nicknamed " master keys", and their use is known as "Avon calling", alluding to the Avon brand of cosmetics which was sold door-to-door. Ideally, breaching rounds m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sintering
Clinker nodules produced by sintering Sintering or frittage is the process of compacting and forming a solid mass of material by pressure or heat without melting it to the point of liquefaction. Sintering happens as part of a manufacturing process used with metals, ceramics, plastics, and other materials. The atoms in the materials diffuse across the boundaries of the particles, fusing the particles together and creating one solid piece. Because the sintering temperature does not have to reach the melting point of the material, sintering is often chosen as the shaping process for materials with extremely high melting points such as tungsten and molybdenum. The study of sintering in metallurgical powder-related processes is known as powder metallurgy. An example of sintering can be observed when ice cubes in a glass of water adhere to each other, which is driven by the temperature difference between the water and the ice. Examples of pressure-driven sintering are the compact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnum Cartridge
A magnum cartridge is a firearm cartridge with a larger case size than, or derived from, a similar cartridge of the same projectile (bullet) caliber and case shoulder shape. The term derives from the .357 Magnum, the original cartridge with this designation.

Gauge (firearms)
The gauge (or commonly bore in British English) of a firearm is a unit of measurement used to express the inner diameter (bore diameter) of the barrel. Gauge is determined from the weight of a solid sphere of lead that will fit the bore of the firearm and is expressed as the multiplicative inverse of the sphere's weight as a fraction of a pound, e.g., a one-twelfth pound lead ball fits a 12-gauge bore. Thus there are twelve 12-gauge balls per pound, etc. The term is related to the measurement of cannon, which were also measured by the weight of their iron round shot; an 8-pounder would fire an 8 lb (3.6 kg) ball. Gauge is commonly used today in reference to shotguns, though historically it was also used in large double rifles, which were made in sizes up to 2 bore during their heyday in the 1880s, being originally loaded with black powder cartridges. These very large rifles, called "elephant guns", were intended for use primarily in Africa and Asia for hunting large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M26 Modular Accessory Shotgun System
The M26-MASS (Modular Accessory Shotgun System) is a shotgun configured as an underbarrel ancillary weapon attachment mounted onto the handguard of a service rifle, usually the M16 rifle, M16/M4 carbine, M4 family of Military of the United States, United States military, essentially making the host weapon a combination gun. It can also be operated as a stand-alone shotgun by attachment to a pistol grip/collapsible buttstock module. Rollout commenced in 2013, replacing the Mossberg 500, M500 shotguns in service. Development The M26-MASS is a lightweight underbarrel shotgun configured to be secured to a main rifle, developed by C-More Systems and manufactured by Vertu Corporation and originally marketed toward United States Special Operations Command, special operations forces. It attracted the interest of soldiers being War in Afghanistan (2001–present), deployed to Afghanistan who wanted a lightweight system that could eliminate the need to carry additional weapons.

KAC Masterkey
The Masterkey is a door breaching shotgun system manufactured by Knight's Armament Company. The Masterkey project was initiated during the 1980s to provide assault rifles with a potent built-in door breaching tool. Individual soldiers were often forced to carry a breaching shotgun in addition to their standard issue rifle, but the Masterkey removes this need. The system consists of a Remington 870 12 gauge pump-action shotgun mounted on an M16 or M4 assault rifle in an underbarrel configuration, much like the M203 grenade launcher. It has a 3-round internal magazine and can carry a fourth round in the chamber. The shotgun can only be awkwardly operated independently because it has no grip behind the trigger—when firing the Masterkey, the rifle's magazine must be used as a makeshift pistol grip. Independent stocks and grips for the 870 are available for use, but they are incompatible with the M16 barrel mount. KAC makes an independent stock for the Masterkey that also can be ...

Riot Shotgun
A riot shotgun is a shotgun designed or modified for use as a primarily defensive weapon, by the use of a short barrel and sometimes a larger magazine capacity than shotguns marketed for hunting. The riot shotgun is used by military personnel for guard duty and was at one time used for riot control, and is commonly used as a door breaching and patrol weapon by law enforcement personnel, as well as a home defense weapon by civilians. Guns of this type are often labeled as breaching shotguns, tactical shotguns or special-purpose shotguns to denote the larger scope of their use; however, these are largely marketing terms. Characteristics The primary characteristic of a riot shotgun is a "short" barrel (generally 14 to 20" long; 18" is the shortest length available to civilians in the U.S. that is not subject to additional federal ATF regulation) which makes the shotgun more compact and easier to handle, easier to stow inside a police vehicle, and more suitable for quick aiming at ( ...

Combat Shotgun
A combat shotgun is a shotgun issued by militaries for warfare. The earliest shotguns specifically designed for combat were the trench guns or trench shotguns issued in World War I. While limited in range, the multiple projectiles typically used in a shotgun shell provide increased hit probability unmatched by other small arms. History While the sporting shotgun traces its ancestry back to the fowling piece, which was a refinement of the smoothbore musket, the combat shotgun bears more kinship to the shorter blunderbuss. Invented in the 16th century by the Dutch, the blunderbuss was used through the 18th century in warfare by the British, Austrian, Spanish (like the Escopeteros Voluntarios de Cadiz, formed in 1804 or the Compañía de Escopeteros de las Salinas, among others) and Prussian regiments, as well as in the American colonies. As use of the blunderbuss declined, the United States military began loading smaller lead shot (buckshot) in combination with their large ...

Master Keying
A master key operates a set of several locks. Usually, there is nothing special about the key itself, but rather the locks into which it will fit. These master-keyed locks are configured to operate with two, or more, different keys: one specific to each lock (the change key), which cannot operate any of the others in the set, and the master key, which operates all the locks in the set. Locks that have master keys have a second set of the mechanism used to operate them that is identical to all of the others in the set of locks. For example, master keyed pin tumbler locks often have two shear points at each pin position, one for the change key and one for the master key. A far more secure (and more expensive) system has two cylinders in each lock, one for the change key and one for the master key. Master keyed lock systems generally reduce overall security. The fact that some pin chambers have two shear points allows for more options when picking and it also allows for more keys t ...

SWAT
In the United States, a SWAT team (special weapons and tactics, originally special weapons assault team) is a police tactical unit that uses specialized or military equipment and tactics. Although they were first created in the 1960s to handle riot control or violent confrontations with criminals, the number and usage of SWAT teams increased in the 1980s and 1990s during the War on Drugs and later in the aftermath of the September 11 attacks. In the United States by 2005, SWAT teams were deployed 50,000 times every year, almost 80% of the time to serve search warrants, most often for narcotics. By 2015 that number had increased to nearly 80,000 times a year. SWAT teams are increasingly equipped with military-type hardware and trained to deploy against threats of terrorism, for crowd control, hostage taking, and in situations beyond the capabilities of ordinary law enforcement, sometimes deemed "high-risk". SWAT units are often equipped with automatic and specialized fir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frangible Round
Frangible bullets are intended to disintegrate into tiny particles upon target impact to minimize their penetration of other objects. Small particles are slowed more rapidly by air resistance, and are less likely to cause injury or damage to persons and objects distant from the point of bullet impact. Most frangible bullets are subject to brittle failure upon striking a hard target. This mechanism has been used to minimize the tendency of malleable lead and copper bullets to ricochet from hard targets as large, cohesive particles. Brittle failure may occur at subsonic velocity. Attempting to crimp a brittle frangible bullet into the cartridge case may break the bullet. Brittle frangible bullets may break during the self-loading cycle of semi-automatic firearms; and those fired from revolvers often break as the bullet encounters the barrel forcing cone after leaving the cylinder. Manufacturing Powder metallurgy techniques fabricate bullets from mixtures of powdered metals (typic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
