Springfield Model 1877
The Springfield Model 1877 was a variant of the Springfield Model 1873 carbine. In 1877, many changes were made to both the Model 1873 rifle and the Model 1873 carbine (the carbine was just a shorter version of the rifle). Historically, the Model 1877 rifle has just been considered to be a variant of the Model 1873, while the Model 1877 carbine has been considered to be a separate model. The most visible change was made to the stock. The buttstock comb was extended further forward on the wrist to strengthen the wrist's weak spot. The wrist itself was also thickened. Prior to 1877, the trapdoor breechblock had a high arch machined out of it, making it lighter. The Model 1877 no longer had the arch machined out of it, though the reason for this modification is not clear. Gas ports along the upper ridges of the receiver were also extended, which may explain why the arch on the breechblock was removed at the same time. After the Battle of Little Bighorn, Springfield Armory was assi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breech-loading Weapon
A breechloader is a firearm in which the user loads the ammunition ( cartridge or shell) via the rear (breech) end of its barrel, as opposed to a muzzleloader, which loads ammunition via the front ( muzzle). Modern firearms are generally breech-loading – except for replicas of vintage weapons. Early firearms before the mid-19th century were almost entirely muzzle-loading. Mortars and the Russian GP-25 grenade launcher are the only muzzleloaders remaining in frequent modern usage. However, referring to a weapon specifically as breech loading is mostly limited to single-shot or otherwise non-repeating firearms, such as double-barreled shotguns. Breech-loading provides the advantage of reduced reloading time, because it is far quicker to load the projectile and propellant into the chamber of a gun/cannon than to reach all the way over to the front end to load ammunition and then push them back down a long tube – especially when the projectile fits tightly ...

United States
The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 U.S. state, states, a Washington, D.C., federal district, five major unincorporated territories, nine United States Minor Outlying Islands, Minor Outlying Islands, and 326 Indian reservations.

Springfield Armory
The Springfield Armory, more formally known as the United States Armory and Arsenal at Springfield located in the city of Springfield, Massachusetts, was the primary center for the manufacture of United States military firearms from 1777 until its closing in 1968. It was the first federal armory and one of the first factories in the United States dedicated to the manufacture of weapons. The site is preserved as the Springfield Armory National Historic Site, Western Massachusetts' only unit of the national park system. It features the world's largest collection of historic American firearms. Famous first as the United States' primary arsenal during the American Revolutionary War, and then as the scene of a confrontation during Shays' Rebellion, the Springfield Armory in the 19th and 20th centuries became the site of numerous technological innovations of global importance, including interchangeable parts, the assembly line style of mass production, and modern business practices, s ...

Trapdoor Mechanism
In firearms, a trapdoor is a form of breech-loading mechanism for rifles in which a hinged breechblock rotates up and forward, resembling the movement of a trapdoor. The Springfield models 1865 and 1873 were best known for first employing this type of action. Specifications The ''trapdoor'' ''mechanism'' employed a hinged breechblock that rotated up and forward, resembling the movement of a trapdoor, to open the breech of the rifle and permit insertion of a cartridge. The hinged breechblock caused these rifles to be named "Trapdoor Springfields". The conversion from musket to breechloader was done by milling open the barrel's breech section and inserting a hinged ''trapdoor'' fastened to the top of the barrel. A thumb-operated cam latch at the rear of the breechblock held it shut when in closed position. The rack-type system extractor was withdrawn automatically as the breechblock was opened and snapped back at the end of its stroke. The firing pin was housed within the bree ...

Open Sights
Iron sights are a system of physical alignment markers (usually made of metallic material) used as a sighting device to assist the accurate aiming of ranged weapons (such as a firearm, airgun, crossbow or even compound bow), or less commonly as a primitive finder sight for optical telescopes. The earliest sighting device, it relies completely on the viewer's naked eye (mostly under ambient lighting), and is distinctly different to optical sights such as telescopic sights, reflector (reflex) sights, holographic sights and laser sights, which make use of optical manipulation and/or active illumination, as well as the newer optoelectronics, which use digital imaging and even incorporate augmented reality. Iron sights are typically composed of two components mounted perpendicularly above the weapon's bore axis: a rear sight nearer (or ''proximally'') to the shooter's eye, and a front sight farther forward (or ''distally'') near the muzzle. During aiming, the shooter aligns hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breechblock
A breechblock (or breech block) is the part of the firearm action that closes the breech of a breech loading weapon (whether small arms or artillery) before or at the moment of firing. It seals the breech and contains the pressure generated by the ignited propellant. Retracting the breechblock allows the chamber to be loaded with a cartridge. Breechblocks are categorised by the type or design of the mechanism by which it is locked or closed for firing. The firearm action more fully refers to the mechanism by which the operator actuates the opening and closing of the breech. Variants A way of closing the breech or chamber is an essential part of any breech-loading weapon or firearm. Perhaps the simplest way of achieving this is a break-action, in which the barrel, forestock and breech pivot on a hinge that joins the front assembly to the rear of the firearm, incorporating the rear of the breech, the butt and usually, the trigger mechanism. A breechblock is a separate c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of Little Bighorn
The Battle of the Little Bighorn, known to the Lakota and other Plains Indians as the Battle of the Greasy Grass, and also commonly referred to as Custer's Last Stand, was an armed engagement between combined forces of the Lakota Sioux, Northern Cheyenne, and Arapaho tribes and the 7th Cavalry Regiment of the United States Army. The battle, which resulted in the defeat of U.S. forces, was the most significant action of the Great Sioux War of 1876. It took place on June 25–26, 1876, along the Little Bighorn River in the Crow Indian Reservation in southeastern Montana Territory. Most battles in the Great Sioux War, including the Battle of the Little Bighorn (14 on the map to the right), "were on lands those Indians had taken from other tribes since 1851". The Lakotas were there without consent from the local Crow tribe, which had treaty on the area. Already in 1873, Crow chief Blackfoot had called for U.S. military actions against the Indian intruders. The steady Lakota inva ...

Springfield Rifle
The term Springfield rifle may refer to any one of several types of small arms produced by the Springfield Armory in Springfield, Massachusetts, for the United States armed forces. In modern usage, the term "Springfield rifle" most commonly refers to the Springfield Model 1903 for its use in both world wars. There were also numerous limited production, experimental, marksmanship, and sporting rifles produced by the Springfield Armory which are referred to as "Springfield rifles". Some examples of the smoothbore Springfield Model 1842 musket that were later modified with rifling and used during the American Civil War may also be referred to as "Springfield rifles". Rifled musket: * Springfield Model 1855 – .58 caliber Maynard tape primer percussion lock rifled musket. * Springfield Model 1861 – .58 caliber percussion lock rifled musket. * Springfield Model 1863 – .58 caliber percussion lock rifled musket.
