OTs-14 Groza
The OTs-14-4 "Groza-4" () is a Russian selective fire bullpup assault rifle chambered for the 9×39mm subsonic cartridge. It was developed in the 1990s at the TsKIB SOO (Central Design and Research Bureau of Sporting and Hunting Arms) in Tula, Russia, Tula, Russia. The weapon is colloquially known as OC-14 or OTs-14 "Groza". The OTs-14-4A "Groza-4" has one derivative, the TKB-0239 (ТКБ-0239), also known as OTs-14-1A "Groza-1", chambered for the 7.62×39mm cartridge. The Groza saw limited use in the Second Chechen War and Russo-Georgian War. However OTs-14 Groza are still by some police force across Russia. History The weapon's chief designers were Valery Telesh, responsible for the GP-25, GP-25 and GP-30 under-barrel grenade launchers, and Yuri Lebedev. The team set out to design an integrated and modular system that would incorporate all the best features of a close-combat long gun into a single weapon based on the AK-74#Variants, AKS-74U. Their first attempt at this was the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bullpup
A bullpup firearm is one with its firing grip located in front of the Chamber (firearms), breech of the weapon, instead of behind it. This creates a weapon with a shorter overall length for a given barrel length, and one that is often lighter, more compact, concealable, and more maneuverable than a conventionally configured firearm. Where it is desirable for troops to be issued a more compact weapon, the use of a bullpup configuration allows for barrel length to be retained, thus preserving muzzle velocity, range, and ballistic effectiveness. The bullpup concept was first tested militarily in 1901 with the British Thorneycroft carbine, but it was not until the Cold War that more successful designs and improvements led to wider adoption. In 1977, the Austrian Federal Army, Austrian Army became the first military force in the world to adopt a bullpup rifle, the Steyr AUG, as a service rifle, principal combat weapon. Since then the militaries in many countries have followed suit w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AK-74
The AK-74 ( Russian: , tr. ''Avtomat Kalashnikova obraztsa 1974 goda'', lit. 'Kalashnikov assault rifle model 1974') is an assault rifle designed by small arms designer Mikhail Kalashnikov in 1974 as a successor to the AKM. While primarily associated with the Soviet Union, it has been used by many countries since the 1970s. It is chambered for the 5.45×39mm cartridge, which replaced the 7.62×39mm cartridge of Kalashnikov's earlier automatic weapons for the Soviet Armed Forces. The rifle first saw service with Soviet forces in the Soviet–Afghan War from 1979. The head of the Afghan bureau of the Inter-Services Intelligence (ISI), the intelligence agency of Pakistan, claimed that the American Central Intelligence Agency (CIA) paid $5,000 for the first AK-74 captured by the Afghan mujahideen during the war. , most countries of the former Soviet Union use the rifle. Licensed copies were produced in Bulgaria (AK-74, AKS-74 and AKS-74U), and in the former East Germany ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Receiver (firearms)
In firearms terminology and law, the firearm frame or receiver is the part of a firearm which integrates other components by providing housing (engineering), housing for internal action (firearms), action components such as the hammer (firearms), hammer, bolt (firearms), bolt or breechblock, firing pin and extractor (firearms), extractor, and has screw thread, threaded interfaces for externally attaching ("receiving") components such as the gun barrel, barrel, stock (firearms), stock, trigger (firearms), trigger mechanism and iron sights, iron/sight (device)#Optical sights, optical sights. Some firearm designs, such as the AR-15 platform, feature receivers that have 2 separate sub-assemblies called the upper receiver which houses the barrel/trunnion, bolt components etc and the lower receiver (Trigger Mechanism Housing in some cases) that holds the fire control group, pistol grip, selector, stock etc. The receiver is often made of forged, machined, or stamped steel or aluminium.

It was introduced on 3 July 1963 together with the Dragunov sniper rifle. Design The PSO-1 was specifically designed for the SVD as a telescopic sight for military designated marksman activities. The current version of the sight is the PSO-1M2. This telescopic sight is different from the original PSO-1 only in that it lacks the now obsolete infrared detector, which was used to detect generation-zero active-infrared night vision devices like the US M2 Sniperscope. The metal body of the PSO-1 is made from a magn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iron Sight
Iron sights are a system of physical alignment markers used as a sighting device to assist the accurate aiming of ranged weapons such as firearms, airguns, crossbows, and bows, or less commonly as a primitive finder sight for optical telescopes. Iron sights, which are typically made of metal, are the earliest and simplest type of sighting device. Since iron sights neither magnify nor illuminate the target, they rely completely on the viewer's naked eye and the available light by which the target is visible. In this respect, iron sights are distinctly different from optical sight designs that employ optical manipulation or active illumination, such as telescopic sights, reflector (reflex) sights, holographic sights, and laser sights. Iron sights are typically composed of two components mounted perpendicularly above the weapon's bore axis: a 'rear sight' nearer (or 'proximal') to the shooter's eye, and a 'front sight' farther forward (or 'distal') near the muzzle.

Closed Bolt
A semi or full-automatic firearm which is said to fire from a closed bolt or closed breech is one where, when ready to fire, a round is in the chamber and the bolt and working parts are forward ''in battery''. When the trigger is pulled, the firing pin or striker fires the round; the action is cycled by the energy of the shot, sending the bolt to the rear, which extracts and ejects the empty cartridge case; and the bolt goes forward, feeding a fresh round from the magazine into the chamber, ready for the next shot. World War I aircraft When World War I era machine guns were being tried for use on aircraft, the Lewis gun was found not to be usable with a gun synchronizer for forward firing through the propeller, due to its firing cycle starting with an open bolt. Maxim style arms fired with a cycle starting with a closed bolt, and since the bullet firing from the gun started the firing cycle, it was much easier to set the synchronizer to trigger the gun only when the prope ...

Carbine
A carbine ( or ) is a long gun that has a barrel shortened from its original length. Most modern carbines are rifles that are compact versions of a longer rifle or are rifles chambered for less powerful cartridges. The smaller size and lighter weight of carbines make them easier to handle. They are typically issued to high-mobility troops such as special operations soldiers and paratroopers, as well as to mounted, artillery, logistics, or other non-infantry personnel whose roles do not require full-sized rifles, although there is a growing tendency for carbines to be issued to front-line soldiers to offset the increasing weight of other issued equipment. An example of this is the M4 carbine, the standard issue carbine of the United States Armed Forces. Etymology The name comes from its first users — cavalry troopers called " carabiniers", from the French ''carabine'', from Old French ''carabin'' (soldier armed with a musket), whose origin is unclear.

Spetsnaz
SpetsnazThe term is borrowed from rus, спецназ, p=spʲɪtsˈnas; abbreviation for or 'Special Purpose Military Units'; or () are special forces in many post-Soviet states. Historically, this term referred to the Soviet Union's Spetsnaz GRU, special operations units of the GRU (Soviet Union), Main Intelligence Directorate of the Soviet General Staff (GRU). Today it refers to special forces branches and task forces subordinate to ministries including defence, internal affairs, or emergency situations in countries that have inherited their special purpose units from the Chronology of Soviet secret police agencies, now-defunct Soviet security agencies. As ''spetsnaz'' is a Russian term, it is typically associated with the special units of Russia, but other post-Soviet states often refer to their special forces units by the term as well, since these nations also inherited their special purpose units from the now-defunct Soviet security agencies.
