Hammer (firearms)
The hammer is a part of a firearm that is used to strike the percussion cap/primer, or a separate firing pin, to ignite the propellant and fire the projectile. It is so called due to the fact that it resembles a hammer in both form and function. The hammer itself is a metal piece that forcefully rotates about a pivot point. Evolution Firearms, initially known as " hand cannons", first became a viable weapon in 1364 through the advancement of chemical technologies to create a gunpowder efficient enough to launch a projectile at high speeds in a hand-held weapon. The issue quickly arose of how to effectively ignite the gunpowder while maintaining the weapon’s aim at the target. Initially, the problem was solved by using a " slow match": a chemically treated piece of rope that would stay lit for an extended period of time. The smoldering end of the rope would then be manually brought into contact with the gunpowder through a touch hole in the barrel of the weapon. when the us ...

Flintlock
Flintlock is a general term for any firearm that uses a flint-striking ignition mechanism, the first of which appeared in Western Europe in the early 16th century. The term may also apply to a particular form of the mechanism itself, also known as the '' true flintlock'', that was introduced in the early 17th century, and gradually replaced earlier firearm-ignition technologies, such as the matchlock, the wheellock, and the earlier flintlock mechanisms such as snaplock and snaphaunce. The true flintlock continued to be in common use for over two centuries, replaced by percussion cap and, later, the cartridge-based systems in the early-to-mid 19th century. Although long superseded by modern firearms, flintlock weapons enjoy continuing popularity with black-powder shooting enthusiasts. History French court gunsmith Marin le Bourgeoys made a firearm incorporating a flintlock mechanism for King Louis XIII shortly after his accession to the throne in 1610. However, firear ...

QBZ-95
The Type 95 automatic rifle () or QBZ-95 is a bullpup assault rifle designed and manufactured by Norinco, and issued since 1995 as the service rifle for the People's Liberation Army, People's Armed Police and various paramilitary law enforcement agencies in the People's Republic of China. The rifle's designation "QBZ" stands for "' light weapon' (''Qīng Wŭqì'')—'rifle' (''Bùqiāng'')—'automatic' (''Zìdòng'')", in keeping with the coding standards of the Chinese defense industry. The QBZ-95 is the flagship of the Type 95 gun family (95式枪族), a family of firearms sharing a common receiver design, which includes a standard rifle, a carbine and light support weapon variants. It fires the 5.8×42mm DBP87, an indigenous intermediate cartridge. An export version chambered for 5.56×45mm NATO, the QBZ-97, is available for sale in Canada and various countries in Southeast Asia, South Asia and East Africa.

Striker-fired
A firing pin or striker is a part of the firing mechanism of a firearm that impacts the primer in the base of a cartridge and causes it to fire. In firearms terminology, a striker is a particular type of firing pin where a compressed spring acts directly on the firing pin to provide the impact force rather than it being struck by a hammer. The terms may also be used for a component of equipment or a device which has a similar function. Such equipment or devices include: artillery, munitions and pyrotechnics. Firearms The typical firing pin is a thin, simple rod with a hardened, rounded tip that strikes and crushes the primer. The rounded end ensures the primer is indented rather than pierced (to contain propellant gasses). It sits within a hole through the breechblock and is struck by the hammer when the trigger is "pulled". A light firing-pin spring is often used to keep the firing pin rearward. It may be termed a ''firing-pin return spring'', since it returns it to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Single-action Revolvers
A trigger is a mechanism that actuates the function of a ranged weapon such as a firearm, airgun, crossbow, or speargun. The word may also be used to describe a switch that initiates the operation of other non-shooting devices such as a trap, a power tool or a quick release. A small amount of energy applied to the trigger leads to the release of much more energy. Most triggers use a small flattened lever (called the ''trigger blade'') depressed by the index finger, but some weapons such as the M2 Browning machine gun or the Iron Horse TOR ("thumb-operated receiver") use a push-button-like thumb-actuated trigger design, and others like the Springfield Armory M6 Scout use a squeeze-bar trigger similar to the "ticklers" on medieval European crossbows. Although the word "trigger" technically implies the entire mechanism (known as the ''trigger group''), colloquially it is usually used to refer specifically to the trigger blade. Most firearm triggers are "single-action", meani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
West Sacramento, California
West Sacramento (also known as West Sac) is a city in Yolo County, California, United States. The city is separated from Sacramento by the Sacramento River, which also separates Sacramento and Yolo counties. It is a fast-growing community; the population was 48,744 at the 2010 census, up from 31,615 at the 2000 census. The traditional industrial center of the region since the Gold Rush era, West Sacramento is home to a diverse economy and is one of the area's top four employment centers. The United States Conference of Mayors named West Sacramento as the Most Livable City in America in 2014 in the category of cities with fewer than 100,000 residents. West Sacramento is part of the Sacramento–Arden Arcade–Roseville Metropolitan Statistical Area which has a population (2000) of approximately 1,796,857 (July 1, 2016 estimate placed the population at 2,296,418).

Cartridge (firearms)
A cartridge or a round is a type of pre-assembled firearm ammunition packaging a projectile ( bullet, shot, or slug), a propellant substance (usually either smokeless powder or black powder) and an ignition device ( primer) within a metallic, paper, or plastic case that is precisely made to fit within the barrel chamber of a breechloading gun, for the practical purpose of convenient transportation and handling during shooting. Although in popular usage the term "bullet" is often informally used to refer to a complete cartridge, it is correctly used only to refer to the projectile. Cartridges can be categorized by the type of their primers – a small charge of an impact- or electric-sensitive chemical mixture that is located: at the center of the case head (centerfire); inside the rim ( rimfire); inside the walls on the fold of the case base that is shaped like a cup (cupfire, now obsolete); in a sideways projection that is shaped like a pin (pinfire, now obsolete ...

Caplock Mechanism
The percussion cap or percussion primer, introduced in the early 1820s, is a type of single-use percussion ignition device for muzzle loader firearm locks enabling them to fire reliably in any weather condition. This crucial invention gave rise to the cap lock mechanism or percussion lock system using percussion caps struck by the hammer to set off the gunpowder charge in percussion guns including percussion rifles and cap and ball firearms. Any firearm using a caplock mechanism is a percussion gun. Any long gun with a cap-lock mechanism and rifled barrel is a percussion rifle. Cap and ball describes cap-lock firearms discharging a single bore-diameter spherical bullet with each shot. Description The percussion cap is a small cylinder of copper or brass with one closed end. Inside the closed end is a small amount of a shock-sensitive explosive material such as mercuric fulminate (discovered in 1800; it was the only practical detonator used from about 1850 to the early ...

Mercury(II) Fulminate
Mercury(II) fulminate, or Hg(CNO)2, is a primary explosive. It is highly sensitive to friction, heat and shock and is mainly used as a trigger for other explosives in percussion caps and detonators. Mercury(II) cyanate, though its chemical formula is identical, has a different atomic arrangement; the cyanate and fulminate anions are isomers. First used as a priming composition in small copper caps beginning in the 1820s, mercury fulminate quickly replaced flints as a means to ignite black powder charges in muzzle-loading firearms. Later, during the late 19th century and most of the 20th century, mercury fulminate became widely used in primers for self-contained rifle and pistol ammunition; it was the only practical detonator for firing projectiles until the early 20th century. Mercury fulminate has the distinct advantage over potassium chlorate of being non-corrosive, but it is known to weaken with time, by decomposing into its constituent elements. The reduced mercury which re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
