ﾄ兄 2000
The ﾄ兄 2000 is a prototype 5.56 mm caliber Czech weapon system, consisting of a standard rifle, carbine and light machine gun. The system was developed in 1991 after adapting the LADA firearm prototype (chambered for the 5.45ﾃ39mm M74 cartridge to the standard NATO 5.56ﾃ45mm round with the SS109 bullet.Woﾅｺniak, Ryszard. Encyklopedia najnowszej broni palnej - tom 1 A-F. Bellona. 2001. pp159-160.) J. Denel from the Brno-based Prototypa-ZM company is the chief designer for both systems. The ﾄ兄 2000 (short for ''ﾄ憩skﾃ｡ zbrojovka'', and the number 2000 signifies that this is a weapon system of the year 2000) was to be produced by ﾄ憩skﾃ｡ zbrojovka of Uherskﾃｽ Brod. It was planned to be the new service weapon of the Czech Army, replacing: the 7.62 mm vz. 58 assault rifle, 7.65 mm vz. 61 ﾅkorpion submachine gun and 7.62 mm vz. 59 machine gun. As of 2007, the project has been discontinued. Design details The firearms of the ﾄ兄 2000 series family fall under the category o ...

Grenade Launcher
A grenade launcher is a weapon that fires a specially-designed large-caliber projectile, often with an explosive, smoke or gas warhead. Today, the term generally refers to a class of dedicated firearms firing unitary grenade cartridges. The most common type are man-portable, shoulder-fired weapons issued to individuals, although larger crew-served launchers are issued at higher levels of organisation by military forces. Grenade launchers can either come in the form of standalone weapons (either single-shot or repeating) or attachments mounted to a parent firearm, usually a rifle. Larger crew-served automatic grenade launchers such as the Mk 19 are mounted on tripods or vehicles. Some armored fighting vehicles also mount fixed arrays of short range, single-shot grenade launchers as a means of defense. History Early precursors The earliest devices which could be referred to as grenade launchers were slings, which could be used to throw early ''grenado'' fuse bombs. The a ...

Bayonet
A bayonet (from French ) is a knife, dagger, sword, or spike-shaped weapon designed to fit on the end of the muzzle of a rifle, musket or similar firearm, allowing it to be used as a spear-like weapon.Brayley, Martin, ''Bayonets: An Illustrated History'', Iola, WI: Krause Publications, , (2004), pp. 9窶10, 83窶85. From the 17th century to World War I, it was a weapon for infantry attacks. Today it is considered an ancillary weapon or a weapon of last resort. History The term ''bayonette'' itself dates back to the mid-to-late 16th century, but it is not clear whether bayonets at the time were knives that could be fitted to the ends of firearms, or simply a type of knife. For example, Cotgrave's 1611 ''Dictionarie'' describes the bayonet as "a kind of small flat pocket dagger, furnished with knives; or a great knife to hang at the girdle". Likewise, Pierre Borel wrote in 1655 that a kind of long-knife called a ''bayonette'' was made in Bayonne but does not give any ...

Bipod
A bipod is a V-shaped portable attachment that helps support and steady a device, usually a weapon such as a long gun or a mortar. The term comes from the Latin prefix ''bi-'' and Greek root ''pod'', meaning "two" and "foot" respectively. Bipods are designed to support the weight of the weapon's front portion and barrel, and provide significant stability against unwanted side-to-side movements (i.e. canting) while allowing free movements pivoting around the transverse axis ( pitching). Most modern bipods have foldable and/or telescoping legs, and allow some limited movements around the vertical axis ( panning) and even the longitudinal axis ( tilting). A bipod by itself, with only two supporting legs, is not completely stable and needs to be reinforced by at least one more point of support to be steady, especially against the horizontal shearing force from recoils. This third point of support is typically the buttstock that is firmly pushed/braced against the shooter's body, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flash Suppressor
A flash suppressor, also known as a flash guard, flash eliminator, flash hider, or flash cone, is a muzzle device attached to the muzzle of a rifle that reduces its visible signature while firing by cooling or dispersing the burning gases that exit the muzzle, a phenomenon typical of carbine-length weapons. Its primary intent is to reduce the chances that the shooter will be blinded in low-light shooting conditions. Contrary to popular belief, it is only a minor secondary benefit if a flash suppressor reduces the intensity of the flash visible to the enemy. A flash suppressor is different from a muzzle brake, although they are typically mounted in the same position and sometimes confused with each other. While the former is intended to reduce visible flash, a muzzle brake is designed to reduce recoil inherent to large cartridges and typically does not reduce visible flash. Rationale Pre-20th century rifle designs tended to have longer barrels than modern rifles. A beneficial ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iron Sight
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 his/ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polymer
A polymer (; Greek '' poly-'', "many" + ''-mer'', "part") is a substance or material consisting of very large molecules called macromolecules, composed of many repeating subunits. Due to their broad spectrum of properties, both synthetic and natural polymers play essential and ubiquitous roles in everyday life. Polymers range from familiar synthetic plastics such as polystyrene to natural biopolymers such as DNA and proteins that are fundamental to biological structure and function. Polymers, both natural and synthetic, are created via polymerization of many small molecules, known as monomers. Their consequently large molecular mass, relative to small molecule compounds, produces unique physical properties including toughness, high elasticity, viscoelasticity, and a tendency to form amorphous and semicrystalline structures rather than crystals. The term "polymer" derives from the Greek word ﾏﾎｿﾎｻﾏ済 (''polus'', meaning "many, much") and ﾎｼﾎｭﾏ∃ｿﾏ (''meros'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semi-automatic Firearm
A semi-automatic firearm, also called a self-loading or autoloading firearm (fully automatic and selective fire firearms are also variations on self-loading firearms), is a repeating firearm whose action mechanism ''automatically'' loads a following round of cartridge into the chamber (self-loading) and prepares it for subsequent firing, but requires the shooter to ''manually'' actuate the trigger in order to discharge each shot. Typically, this involves the weapon's action utilizing the excess energy released during the preceding shot (in the form of recoil or high-pressure gas expanding within the bore) to unlock and move the bolt, extracting and ejecting the spent cartridge case from the chamber, re-cocking the firing mechanism, and loading a new cartridge into the firing chamber, all without input from the user. To fire again, however, the user must actively release the trigger, allow it to "reset", before pulling the trigger again to fire off the next round. As a result, eac ...

Selective Fire
Selective fire is the capability of a weapon to be adjusted to fire in semi-automatic, fully automatic, and/or burst mode. The modes are chosen by means of a selector switch, which varies depending on the weapon's design. Some selective-fire weapons have burst fire mechanisms to limit the maximum number of shots fired automatically in this mode. The most common limits are two or three rounds per trigger pull. Fully automatic fire refers to the ability for a weapon to fire continuously until either the feeding mechanism is emptied or the trigger is released. Semi-automatic refers to the ability to fire one round per trigger pull. The presence of selective fire modes on firearms permits more efficient use of rounds to be fired for specific needs, versus having a single mode of operation, such as fully automatic, thereby conserving ammunition while maximizing on-target accuracy and effectiveness. This capability is most commonly found on military weapons of the 20th and 21st centur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Machine Gun
A machine gun is a fully automatic, rifled autoloading firearm designed for sustained direct fire with rifle cartridges. Other automatic firearms such as automatic shotguns and automatic rifles (including assault rifles and battle rifles) are typically designed more for firing short bursts rather than continuous firepower, and are not considered true machine guns. As a class of military kinetic projectile weapon, machine guns are designed to be mainly used as infantry support weapons and generally used when attached to a bipod or tripod, a fixed mount or a heavy weapons platform for stability against recoils. Many machine guns also use belt feeding and open bolt operation, features not normally found on other infantry firearms. Machine guns can be further categorized as light machine guns, medium machine guns, heavy machine guns, general purpose machine guns and squad automatic weapons. Similar automatic firearms of caliber or more are classified as autocannons, rat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
