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 because it resembles a hammer in both form and function. The hammer itself is a metal piece that forcefully rotates about a pivot point. The term tumbler can refer to a part of the hammer or a part mechanically attached to the pivot-point of the hammer, depending on the particular firearm under discussion (see half-cock). According to one source the term tumbler is synonymous with hammer. Evolution In the development of firearms, the flintlock used flint striking steel to produce sparks and initiate firing by igniting the gunpowder used as a propellant. The flint was fixed to a swinging arm called the ''cock''. Prior to firing, the cock was held rearward under spring tension. Pulling the trigger allowed the cock to rotate forward at a speed sufficient to produce sparks when it struck the steel frizzen. ...

Caplock
The percussion cap, percussion primer, or caplock, 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. Its invention gave rise to the caplock mechanism or percussion lock system which used percussion caps struck by the hammer to set off the gunpowder charge in 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 mercury fulminate (discovered in 1800; it was the only practical detonator used from about the mid-19th century to the early 20th century).

Single-action Revolvers
A trigger is a mechanism (engineering), mechanism that Actuator, 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 animal trap, 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 flat or slightly curved 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 crossbow#Medieval Europe, medieval European crossbows. Although the word "trigger" technically implies the entire mechanism (known as the ''trigger group''), colloquially it is usually used to refer ...

Smith & Wesson Safety Hammerless
The Smith & Wesson Safety Hammerless or Smith & Wesson New Departure (nicknamed by collectors as the Lemon Squeezer) is a double-action revolver that was produced from 1887 to 1940 by Smith & Wesson. Based on the Smith & Wesson Model 2 double-action design, the revolver incorporated an hammerless, internal hammer and an external grip safety on its back-strap. It was chambered in .32 S&W and .38 S&W calibers; these revolvers were discontinued prior to World War II, being eclipsed by the stronger hand ejector models. .32 and .38 Safety Hammerless models The Smith & Wesson .38 Safety Hammerless models were produced from 1887 (1888 for the 32) to just before World War II. They were chambered in either .32 S&W or .38 S&W with a five-shot cylinder. They were most often produced with a 2-inch, 3-inch, or 3.5-inch barrels; but some 6" barrelled versions are known to exist. These top-break revolvers were designed for fast reloading and concealed carry as the hammer was internal and would ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Half-cock
Half-cock is when the position of the hammer of a firearm is partially—but not completely—cocked. Many firearms, particularly older firearms, had a notch cut into the hammer allowing half-cock, as this position would neither allow the gun to fire nor permit the hammer-mounted firing pin to rest on a live percussion cap or cartridge. The purpose of the half-cock position has variously been used either for loading a firearm, as a safety mechanism, or for both reasons. The still commonly used English expression of " going off half-cocked" derives from failing to complete the cocking action, leading to the weapon being unable to fire. This is often used to describe someone acting prematurely, as in the case of one preparing to shoot their weapon without having set the firearm into "full-cock" position. Early examples Early flintlocks had required a half-cock position to prime the pan, in preparation for firing the firearm, after loading the main chamber. Some other early typ ...

The M16 (officially Rifle, Caliber 5.56 mm, M16) is a family of assault rifles adapted from the ArmaLite AR-15 rifle for the United States Armed Forces, United States military. The original M16 was a 5.56×45mm NATO, 5.56×45mm automatic rifle with a 20-round magazine. In 1964, the XM16E1 entered US military service as the M16 and in the following year was deployed for jungle warfare operations during the Vietnam War. In 1969, the M16A1 replaced the M14 rifle to become the US military's standard service rifle. The M16A1 incorporated numerous modifications including a bolt-assist ("forward-assist"), chrome-plated bore, protective reinforcement around the magazine release, and revised flash hider. In 1983, the United States Marine Corps, US Marine Corps adopted the M16A2 rifle, and the United States Army, US Army adopted it in 1986.

Marlin 1899 SS Stainless
Marlins are fish from the family Istiophoridae, which includes between 9 and 11 species, depending on the taxonomic authority. Name The family's common name is thought to derive from their resemblance to a sailor's marlinspike. Taxonomy The family name Istiophoridae comes from the genus ''Istiophorus'' which first placed the species ''Istiophorus platypterus'' by George Kearsley Shaw in 1792 from the Greek word ''istion'' meaning "sail" that describes the shape of the species's dorsal fins. Family description Marlins have elongated bodies, a spear-like snout or bill, and a long, rigid dorsal fin which extends forward to form a crest. Marlins, an apex predator, are among the fastest marine swimmers. However, greatly exaggerated speeds are often claimed in popular literature, based on unreliable or outdated reports. The larger species include the Atlantic blue marlin, ''Makaira nigricans'', which can reach in length and in weight and the black marlin, ''Istiompax ind ...

Breechloader
A breechloader is a firearm in which the user loads the ammunition from the breech end of the barrel (i.e., from the rearward, open end of the gun's barrel), as opposed to a muzzleloader, in which the user loads the ammunition from the ( muzzle) end of the barrel. The vast majority of modern firearms are generally breech-loaders, while firearms made before the mid-19th century were mostly smoothbore muzzle-loaders. Only a few muzzleloading weapons, such as mortars, rifle grenades, some rocket launchers, such as the Panzerfaust 3 and RPG-7, and the GP series grenade launchers, have remained in common usage in modern military conflicts. However, referring to a weapon explicitly as breech-loading is mostly limited to weapons where the operator loads ammunition by hand (and not by operating a mechanism such as a bolt-action), such as artillery pieces or break-action small arms. Breech-loading provides the advantage of reduced reloading time because it is far quicker to loa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cartridge (firearms)
A cartridge, also known as a round, is a type of pre-assembled firearm ammunition packaging a projectile ( bullet, shot, or slug), a propellant substance ( smokeless powder, black powder substitute, 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 convenient transportation and handling during shooting. Although in popular usage the term "bullet" is often used to refer to a complete cartridge, the correct usage only refers to the projectile. Military and commercial producers continue to pursue the goal of caseless ammunition. Some artillery ammunition uses the same cartridge concept as found in small arms. In other cases, the artillery shell is separate from the propellant charge. A cartridge without a projectile is called a '' blank''; one that is completely inert (contains no active primer and no propellant) is called a '' dummy''; one that ...
