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 The rack-type system extractor was withdrawn automatically as the breechblock was opened and snapped back at the end of its stroke.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 breec ...

M1867 Russian Krnka
The M1867 Russian Krnka (Винтовка Крнка́) was a breech loading conversion of the muzzle-loading Model 1857 Six Line rifle musket designed by Austro-Hungarian arms maker, Sylvester Krnka. History On January 11, 1869, Sylvester Krnka brought two copies of his rifle to Russia to compete with the domestic breechloading conversion system of Naval Lieutenant Baranov. By the 30th of March, Czar Alexander II ordered the Krnka conversion rifle of 15.24mm caliber to be adopted by the Russian army. Conversions were carried out at the Tula, Sestroretsk, Kiev, & Izhevsk armories. As well as the private firms of Nobel, Standerscheld, & Meingard. Factories that were producing the Carle needle rifles were then ordered from 1869–1873 to not only produce Krnkas, but convert the Carle's to the Krnka system as well. Service Shortly after its adoption, the M1870 Berdan №2 was selected as the main rifle to arm the military. Although the Berdan was meant to replace the Krn ...

Springfield Model 1863
The Springfield Model 1863 was a .58 caliber rifled musket manufactured by the Springfield Armory and independent contractors between 1863 and 1865. The Model 1863 was only a minor improvement over the Springfield Model 1861. As such, it is sometimes classified as just a variant of the Model 1861. The Model 1861, with all of its variants, was the most commonly used longarm in the American Civil War, with over 700,000 manufactured. The Model 1863 also has the distinction of being the last muzzle-loading longarm produced by the Springfield Armory. The Model 1863 was produced in two variants. The Type I eliminated the band springs and replaced the flat barrel bands with oval clamping bands. It also featured a new ramrod, a case-hardened lock, a new hammer, and a redesigned bolster (percussion chamber). Several of these modifications were based upon Colt's contract Model 1861, known as the "Colt special". 273,265 Type I variants were manufactured in 1863. The Type II is sometim ...

Magazine (firearms)
A magazine, often simply called a mag, is an ammunition storage and feeding device for a repeating firearm, either integral within the gun (internal/fixed magazine) or externally attached (detachable magazine). The magazine functions by holding several cartridge (firearms), cartridges within itself and sequentially pushing each one into a position where it may be readily loaded into the gun barrel, barrel chamber (firearms), chamber by the firearm's moving action (firearms), action. The detachable magazine is sometimes colloquially referred to as a "clip (ammunition), clip", although this is technically inaccurate since a clip is actually an accessory device used to help load ammunition into a magazine or cylinder. Magazines come in many shapes and sizes, from integral tubular magazines on lever-action and pump-action rifles and shotguns, that may hold more than five rounds, to detachable box magazines and drum magazines for automatic rifles and light machine guns, that may h ...

Rate Of Fire
Rate of fire is the frequency at which a specific weapon can fire or launch its projectiles. This can be influenced by several factors, including operator training level, mechanical limitations, ammunition availability, and weapon condition. In modern weaponry, it is usually measured in rounds per minute (RPM or round/min) or rounds per second (RPS or round/s). There are three different measurements for the rate of fire: cyclic, sustained, and rapid. Cyclic is the maximum rate of fire given only mechanical function, not taking into account degradation of function due to heat, wear, or ammunition constraints. Sustained is the maximum efficient rate of fire given the time taken to load the weapon and keep it cool enough to operate. Finally, rapid is the maximum reasonable rate of fire in an emergency when the rate of fire need not be upheld for long periods. Overview For manually operated weapons such as bolt-action rifles or artillery pieces, the rate of fire is governed primarily ...

Winchester Repeating Arms Company
The Winchester Repeating Arms Company was a prominent American manufacturer of repeating firearms and ammunition. The firm was established in 1866 by Oliver Winchester and was located in New Haven, Connecticut.
