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 rifle designs to be balanced around the pistol grip in a way that gives "pointability" similar to 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 located in the pistol grip used to hold and fire the weapon. However, there are blowback firearms with the magazine located in the grip that do not use a telescopin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CZ Model 25
The CZ Model 25 (properly, Sa 25 or Sa vz. 48b/samopal vz. 48b – ''samopal vzor 48 výsadkový'', "submachine gun model year 1948 para") was perhaps the best known of a series of Czechoslovak designed submachine guns introduced in 1948. There were four generally very similar submachine guns in this series: the Sa 23, Sa 24, Sa 25, and Sa 26. The primary designer was Jaroslav Holeček (September, 15 1923–October, 12 1997), chief engineer of the Česká zbrojovka Uherský Brod arms factory. Design The Sa 23 series utilize a straightforward blowback action, with no locked breech, and fire from the open bolt position. They also use a progressive trigger for selecting between semi-automatic fire and fully automatic fire. Lightly pulling on the trigger will fire a single shot. Pulling the trigger farther to the rear in a continuous motion will fire fully automatically, until the trigger is released or the magazine is empty. The Sa 23 series were submachine guns with a ...

Steyr MPi 69
The Steyr MPi 69 is a 9×19mm submachine gun of the late 20th century made by the Austrian firm Steyr. Characteristics The MPi 69 is shaped much like other telescoping bolt submachineguns, such as the MAC 10 or Uzi. It has a vertical pistol handgrip into which the magazine is inserted, and a longer horizontal front grip area; it also has a folding stock. Featuring a design unusual among modern submachine guns, the MPi 69 is cocked by a dual-purpose lever also used as the front sling attachment point. The forward handgrip and vertical pistol handgrip are all one large plastic molding, forming the front and center bottom part of the weapon. The receiver proper is a square metal tube which partly nestles inside the plastic handgrip. Production status In 1990, the MPi 81 was replaced by the TMP in the product line, though the TMP was also discontinued by Steyr, which sold the design to Brügger & Thomet; it was subsequently improved as the Brügger & Thomet MP9 The Brügger & ...

Patria Submachine Gun
The Military Armament Corporation Model 10, officially abbreviated as "M10" or "M-10", and more commonly known as the MAC-10, is a compact, blowback operated machine pistol/submachine gun that was developed by Gordon B. Ingram in 1964. It is chambered in either .45 ACP or 9mm. A two-stage suppressor by Sionics was designed for the MAC-10, which not only abates the noise created, but makes it easier to control on full automatic (although it also makes the gun far less compact and concealable). Military Armament Corporation never used the "MAC-10" nomenclature in its catalogs or sales literature, but "MAC-10" is frequently used by Title II dealers, gun writers, and collectors. For a decade, the semi-automatic pistol version of the weapon was forbidden in the U.S. under the assault weapons ban enacted by Congress in 1994. Design The MAC-10 is built predominantly from steel stampings. A notched cocking handle protrudes from the top of the receiver, and turning the handle 90° ...

MGP-15 Submachine Gun
The MGP-15 is a submachine gun designed for issue to special forces made by SIMA-CEFAR, updated with a longer barrel and other features. The name was changed from previous MGP models due to modifications, including a change to a barrel with a threaded muzzle, usually fitted with a screwed-on muzzle cap, that allows a suppressor to be quickly screwed on. Design Like all MGP submachine guns, the weapon can utilize Uzi submachine gun magazines.Hogg, page 207. A folding butt stock is provided, so arranged that with the butt folded along the right-hand side of the receiver the butt plate can act as a form of foregrip. Variants * MGP-84 : An upgraded version of the MGP-15. Used in close protection duties. * MGP-14 : A semi-automatic version of the MGP-84, which has a folding forward grip. Also known as the MGP-14 Micro or as the MGP-14 Pistol. For a time, it was known as the MGP-84C. References Bibliography * See also * MGP submachine gun The Peruvian MGP series is a family ...

SM-9
The STEN (or Sten gun) is a family of British submachine guns chambered in 9×19mm which were used extensively by British and Commonwealth forces throughout World War II and the Korean War. They had a simple design and very low production cost, making them effective insurgency weapons for resistance groups, and they continue to see usage to this day by irregular military forces. The Sten served as the basis for the Sterling submachine gun, which replaced the Sten in British service until the 1990s, when it, and all other submachine guns, were replaced by the SA80. The Sten is a select fire, blowback-operated weapon which mounts its magazine on the left. Sten is an acronym, from the names of the weapon's chief designers, Major Reginald V. Shepherd and Harold J. Turpin, and "En" for the Enfield factory. Over four million Stens in various versions were made in the 1940s, making it the second most produced submachine gun of the Second World War, after the Soviet PPSh-41. His ...

MP-40
The MP 40 (''Maschinenpistole 40'') is a submachine gun chambered for the 9×19mm Parabellum cartridge. It was developed in Nazi Germany and used extensively by the Axis powers during World War II. Designed in 1938 by Heinrich Vollmer with inspiration from its predecessor the MP 38, it was heavily used by infantrymen (particularly platoon and squad leaders), and by paratroopers, on the Eastern and Western Fronts as well as armoured fighting vehicle crews. Its advanced and modern features made it a favorite among soldiers and popular in countries from various parts of the world after the war. It was often called "Schmeisser" by the Allies, after Hugo Schmeisser, who designed the MP 18, although he was not involved in the design or production of the MP 40. The weapon's other variants included the MP 40/I and the MP 41. From 1940 to 1945, an estimated 1.1 million were produced by Erma Werke.

Recoil
Recoil (often called knockback, kickback or simply kick) is the rearward thrust generated when a gun is being discharged. In technical terms, the recoil is a result of conservation of momentum, as according to Newton's third law the force required to accelerate something will evoke an equal but opposite reactional force, which means the forward momentum gained by the projectile and exhaust gases (ejectae) will be mathematically balanced out by an equal and opposite momentum exerted back upon the gun. In hand-held small arms, the recoil momentum will be eventually transferred to the ground, but will do so through the body of the shooter hence resulting in a noticeable impulse commonly referred to as a "kick". In heavier mounted guns, such as heavy machine guns or artillery pieces, recoil momentum is transferred to the Earth's surface through the platform on which the weapon is mounted. In order to bring the rearward moving gun to a halt, the momentum acquired by the gu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uziel Gal
Uziel "Uzi" Gal ( he, עוזיאל "עוזי" גל, born Gotthard Glas; 15 December 1923 – 7 September 2002) was an Israeli firearm designer, best remembered as the designer and namesake of the Uzi submachine gun. Biography Gal was born in Weimar, Germany to Miele and Erich Glas. When the Nazis came to power in 1933, he first moved to the United Kingdom and later in 1936 to Kibbutz Yagur in the British Mandate of Palestine, where he changed his name to Uziel Gal. In 1943, he was arrested for illegally carrying a gun and was sentenced to six years in prison. However, he was pardoned and released in 1946 (serving less than half of his sentence). Gal began designing the Uzi submachine gun shortly after the founding of Israel and the 1948 Arab–Israeli War. In 1951, it was officially adopted by the Israel Defense Forces and was called the Uzi after its creator. Gal did not want the weapon to be named after him but his request was denied. In 1955, he was decorated with the T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uzi Submachine Gun
The Uzi (; he, עוזי, Ūzi; officially cased as UZI) is a family of Israeli open-bolt, blowback-operated submachine guns and machine pistols first designed by Major Uziel "Uzi" Gal in the late 1940s, shortly after the establishment of the State of Israel. It is one of the first weapons to incorporate a telescoping bolt design, which allows the magazine to be housed in the pistol grip for a shorter weapon. The Uzi prototype was finished in 1950. It was first introduced to Israel Defense Forces (IDF) special forces in 1954, and the weapon was placed into general issue two years later. The IDF supplied Uzis to rear-echelon troops, officers, artillery troops and tank crews, as well as a frontline weapon by elite light infantry assault forces. The Uzi has been exported to over 90 countries. Over its service lifetime, it has been manufactured by Israel Military Industries, FN Herstal, and other manufacturers. From the 1960s through to the 1980s, more Uzi submachine guns were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barrel Shroud
A barrel shroud is an external covering that envelops (either partially or full-length) the barrel of a firearm, to prevent unwanted direct contact with the barrel (e.g. accidental collision with surrounding objects, or the user accidentally touching a hot barrel, which can lead to burns). Moving coverings such as pistol slides, fore-end extension of the gunstock/chassis that do not fully encircle the barrel, and the receiver (or frame) of a firearm itself are generally not described as barrel shrouds, though they can functionally act as such. In shotguns, a thin, slim partial shroud known as a rib is often mounted above barrel to shield away the mirage generated by barrel heat, which can interfere with aiming. Full-length barrel shrouds are commonly featured on air-cooled machine guns, where frequent rapid bursts or sustained automatic fire will leave the barrel extremely hot and dangerous to the user. However, shrouds can also be utilized on semi-automatic firearms, espe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
