Škorpion
The Škorpion vz. 61 (or Sa vz. 61 Skorpion) is a Czechoslovak machine pistol developed in 1959 by Miroslav Rybář (1924–1970) and produced under the official designation Samopal vzor 61 ("submachine gun model 1961") by the Česká zbrojovka arms factory in Uherský Brod from 1963 to 1979. The standard version uses .32 ACP ammunition. History The Škorpion was developed in the late 1950s by Miroslav Rybář with the working name "model 59". The design was completed in 1961 and named "Samopal Vz. 61". Design details Operating mechanism The Škorpion is a select-fire, straight blowback-operated weapon that fires from the closed bolt position. The .32 ACP cartridge used produces a very low recoil impulse and this enables simple unlocked blowback operation to be employed; there is no delay mechanism and the cartridge is supported only by the inertia of the bolt and the strength of the return springs. When fired, gas pressure drives the case back in the chamber against th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Machine Pistol
A machine pistol is a handgun that is capable of automatic firearm, fully automatic fire, including shoulder stock, stockless handgun-style submachine guns. The Austrians introduced the world's first machine pistol, the Steyr M1912 pistol#Maschinenpistole M.12 Patrone 16, ''Steyr Repetierpistole'' M1912/P16, during World War I. The Germans also experimented with machine pistols, by converting various types of semi-automatic pistols to full-auto, leading to the development of the first practical submachine guns. During World War II, machine pistol development was widely disregarded in favor of submachine gun mass-production. After the war, machine pistol development was limited and only a handful of manufacturers would develop new designs, with varying degrees of success. This concept would eventually lead to the development of the personal defense weapon or PDW. Today, machine pistols are considered special-purpose weapons with limited utility, with their original niche being fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CZ Scorpion Evo 3
The CZ Scorpion EVO 3 is a 9mm carbine manufactured by Česká zbrojovka Uherský Brod, the select-fire submachine gun variant is designated A1, and the Semi-automatic firearm, semi-automatic variant is designated S1. The EVO 3 designation denotes that the firearm is a third generation of CZ's line of small submachine guns started by the Škorpion, Škorpion vz. 61, which is mechanically unrelated. Design details The Scorpion Evo 3 is a blowback operated carbine evolved from a Slovakia, Slovak prototype submachine gun developed by Laugo. Chambered in 9×19mm Parabellum, the Scorpion EVO 3 is mostly polymer, making it a lightweight, compact submachine gun designed to be easily maneuvered in confined spaces. The A1 variant features a standard left-side non-reciprocating charging handle, although it is ambidextrous and can be switched from side-to-side. It also has an ambidextrous select fire switch, giving the operator the choice of "safe", semi-automatic, three-round burst, or ...

32 ACP
.32 ACP (Automatic Colt Pistol, also known as the .32 Auto, .32 Automatic, 7.65mm Browning, or 7.65×17mmSR) is a centerfire pistol Cartridge (firearms), cartridge. It is a Rim (firearms)#Semi-rimmed, semi-rimmed, straight-walled cartridge developed by firearms designer John Browning, initially for use in the FN M1900 semi-automatic pistol. It was introduced in 1899 by Fabrique Nationale. History John Browning engineered a number of modern semi-automatic pistol mechanisms and cartridges. As his first pistol cartridge, the .32 ACP needed a straight wall for reliable Blowback (firearms), blowback operation as well as a small rim for reliable feeding from a box magazine. The cartridge Headspace (firearms), headspaces on the rim. The cartridge was a success and was adopted by dozens of countries and many governmental agencies. When the .32 ACP cartridge was introduced, it was immediately popular and was available in several blowback automatic pistols of the day, including the Colt Mo ...

Blowback (firearms)
Blowback is a system of operation for self-loading firearms that obtains energy from the motion of the cartridge case as it is pushed to the rear by expanding gas created by the ignition of the propellant charge. Several blowback systems exist within this broad principle of operation, each distinguished by the methods used to control bolt movement. In most actions that use blowback operation, the breech is not locked mechanically at the time of firing: the inertia of the bolt and recoil , relative to the weight of the bullet, delay opening of the breech until the bullet has left the barrel. A few locked breech designs use a form of blowback (example: primer actuation) to perform the unlocking function. The blowback principle may be considered a simplified form of gas operation, since the cartridge case behaves like a piston driven by the powder gases. Other operating principles for self-loading firearms include delayed blowback, blow forward, gas operation, and recoil op ...

Inertia
Inertia is the natural tendency of objects in motion to stay in motion and objects at rest to stay at rest, unless a force causes the velocity to change. It is one of the fundamental principles in classical physics, and described by Isaac Newton in his Newton%27s_laws_of_motion#First, first law of motion (also known as The Principle of Inertia). It is one of the primary manifestations of mass, one of the core quantitative properties of physical systems. Newton writes: In his 1687 work ''Philosophiæ Naturalis Principia Mathematica'', Newton defined inertia as a property: History and development Early understanding of inertial motion Joseph NeedhamProfessor John H. Lienhard points out the Mozi (book), Mozi – based on a Chinese text from the Warring States period (475–221 BCE) – as having given the first description of inertia. Before the European Renaissance, the prevailing theory of motion in western philosophy was that of Aristotle (384–322 BCE). On the surface ...

Telescoping Bolt
A telescoping bolt (also known as an overhung bolt) is a firearm bolt which telescopes over, that is, wraps around and past, the breech end of the barrel. This feature reduces the required length of a weapon such as a submachine gun significantly, and it allows compact designs to be balanced around the pistol grip in a way that gives "pointability" more like a pistol's. While it would be simpler and easier to shorten the bolt to fit completely behind the breech, the bolt must have a certain amount of mass in order to operate reliably with a given caliber. The telescoping bolt moves some of that mass forward of the bolt face, resulting in a bolt which may be longer overall, but is shorter behind the bolt face. Though technically a different, distinct concept, nearly all telescoping bolt submachine guns use a magazine A magazine is a periodical literature, periodical publication, print or digital, produced on a regular schedule, that contains any of a variety of subject- ...

Czechoslovakia
Czechoslovakia ( ; Czech language, Czech and , ''Česko-Slovensko'') was a landlocked country in Central Europe, created in 1918, when it declared its independence from Austria-Hungary. In 1938, after the Munich Agreement, the Sudetenland became part of Nazi Germany, while the country lost further territories to First Vienna Award, Hungary and Trans-Olza, Poland (the territories of southern Slovakia with a predominantly Hungarian population to Hungary and Zaolzie with a predominantly Polish population to Poland). Between 1939 and 1945, the state ceased to exist, as Slovak state, Slovakia proclaimed its independence and Carpathian Ruthenia became part of Kingdom of Hungary (1920–1946), Hungary, while the German Protectorate of Bohemia and Moravia was proclaimed in the remainder of the Czech Lands. In 1939, after the outbreak of World War II, former Czechoslovak President Edvard Beneš formed Czechoslovak government-in-exile, a government-in-exile and sought recognition from the ...

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 ...
