HK MG5
The Heckler & Koch MG5 (in the development phase also known as the HK121) is a belt-fed 7.62×51mm NATO general-purpose machine gun manufactured by German firearm manufacturer Heckler & Koch. The MG5 resembles the 5.56×45mm NATO Heckler & Koch MG4 light machine gun, which was adopted into German military service in 2005. History Work on the MG5 began, under the HK121 designation, shortly after the development of the MG4 light machine gun that Heckler & Koch initially presented as the HK MG43 at the MILIPOL 2001 trade show in Paris. A prototype of the HK121 was presented to a larger public by Heckler & Koch on the 14th day of the infantry in July 2010 in Hammelburg. In June 2013, it was announced that Germany was testing and evaluating 65 samples and planned to buy at least 7,114 of the machine guns for the ''Bundeswehr'' during 2014–2017, in a deal that over time could grow to 12,733 HK5s. The MG5 overall, was designed to be modular and was intended to and started replacing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MG 5
The MG5 is a series of compact cars that has been produced by SAIC Motor under the MG marque since 2012. The first generation MG 5 was launched on 28 March 2012 in China, and shares the same automotive platform as the Roewe 350 saloon car. In China, the first generation hatchback was sold as the MG5, while the sedan was sold as the MG GT. The first-generation MG GT was also sold as the MG 5 in several markets. The second-generation model is marketed as the MG5 in China and Thailand, and either the MG5 GT or MG GT elsewhere.

Trigger (firearms)
A trigger is a mechanism that actuates the function of a ranged weapon such as a firearm, airgun, crossbow, or speargun. The word may also be used to describe a switch that initiates the operation of other non-shooting devices such as a trap, a power tool or a quick release. A small amount of energy applied to the trigger leads to the release of much more energy. Most triggers use a small flattened lever (called the ''trigger blade'') depressed by the index finger, but some weapons such as the M2 Browning machine gun or the Iron Horse TOR ("thumb-operated receiver") use a push-button-like thumb-actuated trigger design, and others like the Springfield Armory M6 Scout use a squeeze-bar trigger similar to the "ticklers" on medieval European crossbows. Although the word "trigger" technically implies the entire mechanism (known as the ''trigger group''), colloquially it is usually used to refer specifically to the trigger blade. Most firearm triggers are "single-action", ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Night-vision Device
A night-vision device (NVD), also known as a night optical/observation device (NOD), night-vision goggle (NVG), is an optoelectronic device that allows visualization of images in low levels of light, improving the user's night vision. The device enhances ambient visible light and converts near-infrared light into visible light which can be seen by the user; this is known as I2 ( image intensification). By comparison, viewing of infrared thermal radiation is referred to as thermal imaging and operates in a different section of the infrared spectrum. A night vision device usually consists of an image intensifier tube, a protective housing, and may have some type of mounting system. Many NVDs also include a protective sacrificial lens, mounted over the front lens (ie. objective lens) on NVDs to protect the latter from damage by environmental hazards and some can incorporate [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Milliradian
A milliradian ( SI-symbol mrad, sometimes also abbreviated mil) is an SI derived unit for angular measurement which is defined as a thousandth of a radian (0.001 radian). Milliradians are used in adjustment of firearm sights by adjusting the angle of the sight compared to the barrel (up, down, left, or right). Milliradians are also used for comparing shot groupings, or to compare the difficulty of hitting different sized shooting targets at different distances. When using a scope with both mrad adjustment and a reticle with mrad markings (called an "mrad/mrad scope"), the shooter can use the reticle as a ruler to count the number of mrads a shot was off-target, which directly translates to the sight adjustment needed to hit the target with a follow up shot. Optics with mrad markings in the reticle can also be used to make a range estimation of a known size target, or vice versa, to determine a target size if the distance is known, a practice called "milling". Milliradians ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minute And Second Of Arc
A minute of arc, arcminute (arcmin), arc minute, or minute arc, denoted by the symbol , is a unit of angular measurement equal to of one degree. Since one degree is of a turn (or complete rotation), one minute of arc is of a turn. The nautical mile (nmi) was originally defined as the arc length of a minute of latitude on a spherical Earth, so the actual Earth circumference is very near . A minute of arc is of a radian. A second of arc, arcsecond (arcsec), or arc second, denoted by the symbol , is of an arcminute, of a degree, of a turn, and (about ) of a radian. These units originated in Babylonian astronomy as sexagesimal subdivisions of the degree; they are used in fields that involve very small angles, such as astronomy, optometry, ophthalmology, optics, navigation, land surveying, and marksmanship. To express even smaller angles, standard SI prefixes can be employed; the milliarcsecond (mas) and microarcsecond (μas), for instance, are commonly us ...

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 alig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MG3 Zerfallgurt
The MG 3 is a German general-purpose machine gun chambered for the 7.62×51mm NATO cartridge. The weapon's design is derived from the World War II era MG 42 ''Einheitsmaschinengewehr'' (Universal machine gun) that fired the 7.92×57mm Mauser round.Woźniak, Ryszard: ''Encyklopedia najnowszej broni palnej—tom 3 M-P'', page 106. Bellona, 2001. The MG 3 was standardized in the late 1950s and adopted into service with the newly formed ''Bundeswehr'', where it continues to serve to this day as a squad support weapon and a vehicle-mounted machine gun. The weapon and its derivatives have also been acquired by the armed forces of over 40 countries. Production rights to the machine gun were purchased by Italy ( MG 42/59), Spain, Pakistan (MG 1A3), Greece, Iran, Sudan and Turkey. History At the end of World War II the original technical drawings and data for the 7.92×57mm Mauser chambered MG 42 were captured by the Soviets. These would eventually find their way to Czechoslovakia and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rate Of Fire
Rate of fire is the frequency at which a specific weapon can fire or launch its projectiles. This can be influenced by several factors, including operator training level, mechanical limitations, ammunition availability, and weapon condition. In modern weaponry, it is usually measured in rounds per minute (RPM or round/min) or rounds per second (RPS or round/s). There are three different measurements for the rate of fire: cyclic, sustained, and rapid. Cyclic is the maximum rate of fire given only mechanical function, not taking into account degradation of function due to heat, wear, or ammunition constraints. Sustained is the maximum efficient rate of fire given the time taken to load the weapon and keep it cool enough to operate. Finally, rapid is the maximum reasonable rate of fire in an emergency when the rate of fire need not be upheld for long periods. Overview For manually operated weapons such as bolt-action rifles or artillery pieces, the rate of fire is governed primarily ...

Chrome Plating
Chrome plating (less commonly chromium plating) is a technique of electroplating a thin layer of chromium onto a metal object. A chrome-plated item is called ''chrome''. The chromed layer can be decorative, provide corrosion resistance, ease of cleaning, or increase surface hardness. Sometimes, a less expensive imitator of chrome may be used for aesthetic purposes. Process Chrome plating a component typically includes these stages: * Degreasing to remove heavy soiling * Manual cleaning to remove all residual traces of dirt and surface impurities * Various pretreatments depending on the substrate * Placement into the chrome plating vat, where it is allowed to warm to solution temperature * Application of plating current for the required time to attain the desired thickness There are many variations to this process, depending on the type of substrate being plated. Different substrates need different etching solutions, such as hydrochloric, hydrofluoric, and sulfuric acids. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Picatinny Rail
The Picatinny rail ( or ), or Pic rail for short, also known as a MIL-STD-1913 rail, 1913 rail or STANAG 2324 rail (cancelled), is a military standard rail interface system that provides a mounting platform for firearm accessories. It was originally used for mounting of scopes atop the receivers of larger caliber rifles. Once established, its use expanded to also attaching other accessories, such as: iron sights, tactical lights, laser aiming modules, night vision devices, reflex sights, holographic sights, foregrips, bipods, slings and bayonets. An updated version of the rail is adopted as a NATO standard as the STANAG 4694 NATO Accessory Rail. Significance Because of their many uses, Picatinny rails and accessories have replaced iron sights in the design of many firearms and available as aftermarket add-on parts for most actions that do not have them integrated, and they are also on the undersides of semi-automatic pistol frames and grips. When adding a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NATO Accessory Rail
The NATO Accessory Rail (NAR), defined by NATO Standardization Agreement (STANAG) 4694, is a rail interface system standard for mounting accessory equipments such as telescopic sights, tactical lights, laser aiming modules, night vision devices, reflex sights, foregrips, bipods and bayonets to small arms such as rifles and pistols. STANAG 4694 was approved by the NATO Army Armaments Group (NAAG), Land Capability Group 1 Dismounted Soldier (LCG1-DS) in 2009. It was published in March 2011. The NATO Accessory Rail is backwards-compatible with the STANAG 2324/MIL-STD 1913 Picatinny rail, which dates back to 3 February 1995, and was designed in conjunction with weapon specialists like Aimpoint, Beretta, Colt Firearms, FN Herstal and Heckler & Koch. The Heckler & Koch G28 designated marksman rifle features NATO Accessory Rails. Technical specifications According to the NATO Army Armaments Group the differences between the MIL-STD 1913 Picatinny rail and the STANAG 4694 are: ...

Loaded Chamber Indicator
Close-up shot of a safety of an M16A2 rifle In firearms, a safety or safety catch is a mechanism used to help prevent the accidental discharge of a firearm, helping to ensure safer handling. Safeties can generally be divided into subtypes such as internal safeties (which typically do not receive input from the user) and external safeties (which typically allow the user to give input, for example, toggling a lever from "on" to "off" or something similar). Sometimes these are called "passive" and "active" safeties (or "automatic" and "manual"), respectively. Firearms with the ability to allow the user to select various fire modes may have separate switches for safety and for mode selection (e.g. Thompson submachine gun) or may have the safety integrated with the mode selector as a fire selector with positions from safe to semi-automatic to full-automatic fire (e.g. M16). Some firearms manufactured after the late 1990s and early 2000s include a mandatory integral locking mechan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
