Rolling Block
A rolling-block action is a single-shot firearm action where the sealing of the breech is done with a specially shaped breechblock able to rotate on a pin. The breechblock is shaped like a section of a circle. The breechblock is locked into place by the hammer, therefore preventing the cartridge from moving backward at the moment of firing. By cocking the hammer, the breechblock can be rotated freely to reload the breech of the weapon. History The Remington Rolling Block rifle is one of the most successful single-shot weapons ever developed. It is a strong, simple, and very reliable action, that is not prone to be jammed by debris or with rough handling. It was invented by Leonard Geiger during the United States Civil War The American Civil War (April 12, 1861May 26, 1865; also known by other names) was a civil war in the United States between the Union ("the North") and the Confederacy ("the South"), which was formed in 1861 by states that had seceded ... an ...

Remington Rolling Block
Remington Rolling Block is a family of breech-loading rifles that was produced from the mid-1860s into the early 20th century by E. Remington and Sons (later Remington Arms). These rifles were made in a variety of calibers, both rimfire and centerfire, including the 12.17x42 mm rimfire, 12.17x44 mm rimfire and 12.17x44 mm rimmed centerfire Swedish and Norwegian cartridges, .43 Spanish (11.15x58mmR), .50-70, .40-70, .45-70 and later in .22 caliber. Later models were produced in .30-03 (Predecessor to .30-06), 7×57mm Mauser, and 8×50mmR Lebel. Development The Remington Rolling Block was developed from the 1863 pattern .50 calibre split breech carbine issued to the US Cavalry during the American Civil War. This earlier weapon was designed by Joseph Rider and Leonard Geiger to fire the same cartridges as the Spencer carbine. The split breech rifle lacked a hammer spur because it self-cocked when the breechblock was opened. Either 1864 or 1865, Remington Engineer Joseph Ride ...

Semi-automatic Rifle
A semi-automatic rifle is a type of rifle that fires a single round each time the Trigger (firearms), trigger is pulled while automatically loading the next Cartridge (firearms), cartridge. These rifles were developed Pre-World War II, and were used throughout World War II. Rifles are firearms designed to be fired while held with both hands and braced against the shooter's shoulder for stability. Externally similar shotguns can fire multiple Shot (pellet), pellets simultaneously through a smoothbore, while rifle Gun barrel, barrels are Rifling, rifled to spin-stabilize individual bullets. The actions of semi-automatic rifles use a portion of the fired cartridge's energy to eject the spent casing and load a new round into the Chamber (firearms), chamber, readying the rifle to be fired again. This design differs from manually operated rifles such as Bolt action, bolt-action and Lever action, lever-action rifles, which need to chamber a cartridge manually before firing again, and ...

Falling-block Action
A falling-block action (also known as a sliding-block or dropping-block action) is a single-shot firearm action in which a solid metal breechblock slides vertically in grooves cut into the breech of the weapon and is actuated by a lever. Description When the breechblock is in the closed (top) position, it seals the chamber from the high pressures created when the cartridge fires and safely transfers the recoil to the action and stock. When the breechblock is in the opened (bottom) position, the rear (breech) end of the chamber is exposed to allow ejection or extraction of the fired case and reloading of an unfired cartridge. It is a very strong action; when the breech is closed, the receiver essentially becomes a single piece of steel (as opposed to other actions that rely on lugs to lock the breech). This type of action is used on artillery pieces, as well as small arms. An additional advantage is the unobstructed loading path, which imposes no limit on the overall length of ...

Break Action
Break action is a type of firearm action in which the barrel(s) are hinged much like a door and rotate perpendicularly to the bore axis to expose the breech and allow loading and unloading of cartridges. A separate operation may be required for the cocking of a hammer to fire the new round. There are many types of break-action firearms; break actions are universal in double-barreled shotguns, double-barreled rifles, combination guns, and are commonly found in single shot pistols (especially derringers), rifles, shotguns, including flare guns, grenade launchers, air guns, and some older revolver designs. They are also known as hinge-action, break-open, break-barrel, break-top, or, on old revolvers, top-break actions. Description Break action The first break-action revolver was patented in France and Britain at the end of December in 1858 by Devisme. A substantial hinge pin joins the two parts of the rifle or shotgun; the stock with its firing mechanism and the fore-piece ...

Pump Action
Pump action is a type of manual firearm action that is operated 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 or striker, and then pushed forward to load a new cartridge into the chamber. Most pump-action firearms use an integral tubular magazine, although some do use detachable box magazines. Pump-action firearms are typically associated with shotguns, although it has also been used in rifles, grenade launchers, and other types of firearms. A firearm using this operating mechanism is colloquially referred to as a pumpgun. Because the forend is manipulated usually with the support hand, a pump-action firearm 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 torqu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lever Action
The toggle-link action used in the iconic Winchester Model 1873 rifle, one of the most famous lever-action firearms Picture showing a Volcanic Pistol A lever action is a type of action for repeating firearms that uses a manually operated cocking handle located around the trigger guard area (often incorporating it) that pivots forward to move the bolt via internal linkages, which will feed and extract cartridges into and out of the chamber, and cock the firing pin mechanism. This contrasts to other type of repeating actions such as the bolt-action, pump-action, semi-automatic, fully automatic, and/or burst mode actions. A firearm using this operating mechanism is colloquially referred to as a levergun. Most lever-action firearms are rifles, but some lever-action shotguns and a few pistols have been made. The Winchester Model 1873 rifle is one of the most famous lever-action firearms, but many manufacturers (notably Henry Repeating Arms and Marlin Firearms) also p ...

Bolt Action
Bolt action is a type of manual firearm action that is operated by ''directly'' manipulating the turn-bolt via a bolt handle, most commonly placed on the right-hand side of the firearm (as most users are right-handed). The majority of bolt-action firearms are rifles, but there are also some variants of shotguns and handguns that are bolt-action. Bolt action firearms are generally repeating firearms, but many single-shot designs are available particularly in shooting sports where single-shot firearms are mandated, such as most Olympic and ISSF rifle disciplines. From the late 19th century all the way through both World Wars, bolt action rifles were the standard infantry service weapons for most of the world's military forces, with the exception of the United States Armed Forces, who used the M1 Garand Semi-automatic rifle. In modern military and law enforcement after the Second World War, bolt-action firearms have been largely replaced by semi-automatic and selec ...

Springfield Model 1870 Remington—Navy
The Springfield Model 1870 rolling-block U.S. Navy rifle was a shipboard small arm for use by the United States Navy, employing the Remington Arms Company rolling-block design, and manufactured under a royalty agreement with Remington. Note: Springfield Model 1870 may also refer to the Springfield Model 1870 rifle. One of the rifles which used the trapdoor breechblock design developed by Erskine S. Allin. Origin During the U.S. Civil War, Joseph Rider experimented with several breech-loading weapon designs. In 1865, he was issued the first patent for what would evolve into the Remington rolling-block action. The Remingtons continued to invest in Rider's work, and met with Ordnance Department officials in the hope of interesting them in this new design called the "Remington System". The U.S. Navy Ordnance Department became interested in the design, and purchased several different models of rifles from 1867 through 1869. Field trials of these various rifles yielded mostly positive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
