Desert Tech MDR
The MDR (an acronym for micro dynamic rifle) is a family of autoloading bullpup rifles designed by Desert Tech (formerly Desert Tactical Arms) in 2014. A second generation version of the rifle is marketed as the MDRX (an acronym for micro dynamic rifle eXtreme). In 2018 a military version of the MDR, the NGSAR, was submitted, but was not one of the finalists in the United States Army Next Generation Squad Weapon Program trials to replace standard issue US army Infantry Weapons. The MDR's first public debut was in 2014 at Shot Show. Design The Desert Tech MDR is a gas operated, conventional rotary bolt bullpup rifle. The gas system features a gas piston located above the barrel and a 6 position manual gas regulator. The MDR rifle is designed to be ambidextrous. The MDR contains an ambidextrous forward and side eject port and viewing window that allows for tool free forward ejector side change. A non reciprocating ambidextrous charging handle is installed on both sides of th ... [...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 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 with other bullpup design ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iron Sights
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 h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forgotten Weapons
Forgotten Weapons is a website and channel appearing on YouTube, Utreon and Full30, created and presented by Ian McCollum, that covers the history of antique, obscure, and historically important firearms. Videos Forgotten Weapons frequently features unusual, rare, odd, experimental, or one-off firearms, such as the paratroop versions of the Empire of Japan's Arisaka Type 99 rifle featuring a folding stock attached to a cabinet hinge. McCollum covers the history of such firearms in detail, and often explains how important certain firearms were to the development of weapon technologies and the history of warfare. He also usually explains the functioning and parts of the gun by dissassembling it. McCollum often borrows the firearms from auction houses, most commonly the Rock Island Auction and Morphy Auctions. He has also written books and articles for ''Popular Mechanics'' on the topic of firearms. Platforms McCollum avoids political topics in favor of exclusively covering tech ...

Automatic Rifle
An automatic rifle is a type of autoloading rifle that is capable of fully automatic fire. Automatic rifles are generally select-fire weapons capable of firing in semi-automatic and automatic firing modes (some automatic rifles are capable of burst-fire as well). Automatic rifles are distinguished from semi-automatic rifles in their ability to fire more than one shot in succession once the trigger is pulled. Most automatic rifles are further subcategorized as battle rifles or assault rifles. History Mannlicher In 1885 Ferdinand Mannlicher made an experimental self-loader based on work begun in 1883 in both semi-automatic and fully automatic modes. It was an impractical failure due to fouling by its black powder ammunition, but it influenced later designs. Furthermore, Mannlicher produced smokeless powder automatic rifles from the early 1890s onwards until his death in 1904. Cei-Rigotti One of the world's first automatic rifles was the Italian Cei-Rigotti. Introduced in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 U.S. Army's M4 carbine, which is standard issue. 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. One theory connects it to an "ancient engine of w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polymer-cased Ammunition
Polymer-cased ammunition (PCA) is firearm ammunition (cartridge) with casings made from synthetic polymer instead of the typical metallic casing. PCA is considered a new alternative that potentially reduces production cost and weight for long guns and handguns. Origin The first references to the possible use of polymers in the manufacture of casings come from the early 1950s. One of the earliest is the patent filed by Jack W. Roske in 1950 and the idea was to use a metal cup joined with a polymer shell "that will be converted to gas during the firing phase to assist in propelling the projectile and thereby permit reduction in the use of the propelling powder charge". Examples * The majority of commonly found shotgun shell hulls are constructed of polymer with metal only found on the lower or rim portions of the shells. * The Steyr ACR was a notable user of polymer cased ammunition. * The US Army ARDEC developed a 5.56mm Telescoped ammunition for its LSAT program. * The Assist ...

Full-powered Rifle Cartridge
A rifle cartridge is a firearm cartridge primarily designed and intended for use in a rifle/carbine, or machine gun. Types Full-powered A full-powered cartridge is a rifle cartridge used interchangeably between service rifles, sniper rifles, and general purpose machine guns. It is a retronym for rifle cartridges used prior to and during World War II. They are primarily used today in general purpose machine guns, designated marksman rifles, and sniper rifles. Magnum A magnum cartridge is a cartridge with a larger case size than, or derived from, a similar cartridge of the same bullet caliber and case shoulder shape. Magnum cartridges allow for more propellant to be loaded within the casing, and thus have a higher muzzle energy. Modern magnum rifle cartridges include .300 RUM, 7mm Remington Magnum, .300 Weatherby Magnum, .460 Weatherby Magnum, .300 Winchester Magnum, .338 Lapua Magnum or .338 Norma Magnum. Today they are primarily used in civilian market for big-game ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intermediate Cartridge
An intermediate cartridge is a rifle/carbine cartridge that has significantly greater power than a pistol cartridge but still has a reduced muzzle energy compared to fully powered cartridges (such as the .303 British, 7.62×54mmR, 7.92×57mm Mauser, 7.7×58mm Arisaka, .30-06 Springfield, or 7.62×51mm NATO), and therefore is regarded as being "intermediate" between traditional rifle and handgun calibers. As their recoil is significantly reduced compared to full-power cartridges, fully automatic rifles firing intermediate cartridges are relatively easy to control. However, even though they are less powerful than a traditional full-power cartridge, the external ballistics are still sufficient for an effective range of , which covers most typical infantry engagement situations in modern warfare. This allowed for the development of the assault rifle, a type of versatile selective fire small arms that is lighter and more compact than traditional battle rifles that fire full-po ...

Desert Tech Forward Eject MDRX 5
A desert is a barren area of landscape where little precipitation occurs and, consequently, living conditions are hostile for plant and animal life. The lack of vegetation exposes the unprotected surface of the ground to denudation. About one-third of the land surface of the Earth is arid or semi-arid. This includes much of the polar regions, where little precipitation occurs, and which are sometimes called polar deserts or "cold deserts". Deserts can be classified by the amount of precipitation that falls, by the temperature that prevails, by the causes of desertification or by their geographical location. Deserts are formed by weathering processes as large variations in temperature between day and night put strains on the rocks, which consequently break in pieces. Although rain seldom occurs in deserts, there are occasional downpours that can result in flash floods. Rain falling on hot rocks can cause them to shatter, and the resulting fragments and rubble strewn over the de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
