Handguard
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 extensions 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 the 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 used on semi-automatic firearms, espe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
KeyMod
KeyMod is a universal interface system for firearm accessory components. The concept was first created by VLTOR Weapon Systems of Tucson, Arizona, and released through Noveske Rifleworks of Grants Pass, Oregon, before being published Open-source software, open sourced in the public domain for adoption by the entire firearms accessory industry. The name "KeyMod" was coined by Eric Kincel (then working for VLTOR Weapon Systems) following the naming trend of other VLTOR accessories with the suffix "Mod" meaning modular, and "Key" being a reference to the key-hole profile of the mounting slots. History VLTOR Weapon Systems had previously pursued a design which was the basis for the KeyMod system. While developing the first prototype systems, Eric Kincel of VLTOR Weapon systems was approached by John Noveske of Noveske Rifleworks with a design for a universal accessory attachment system. After a short collaboration, during which Todd Krawczyk of Noveske Rifleworks suggested an improveme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sling (firearms)
In the context of firearms, a sling is a type of strap or harness designed to allow a shooter to conveniently carry a firearm (usually a long gun such as a rifle, carbine, shotgun, submachine gun or GPMG) on their body, and/or to aid in greater hit probability by allowing the firearm to be better braced and stabilized during aiming. Various types of slings offer their own advantages and disadvantages, and can generally be divided into several categories. Types of setup ; Simple/traditional sling (two-point): The oldest and most familiar design, this sling design has two connection points that attach to the front and rear of the weapon, and allows the shooter to carry the weapon over their back, with the sling draped across the torso, around the neck or over one shoulder. Some two-point slings, if properly made, can act as a shooting aid. ; Ching/CW sling: This type of sling is a component of the Scout Rifle concept, and serves not just as a carrying strap, but as an aid to ...

Stock (firearm)
A gunstock or often simply stock, the back portion of which is also known as a shoulder stock, a buttstock, or simply a butt, is a part of a long gun that provides structural support, to which the barrel, action, and firing mechanism are attached. The stock also provides a means for the shooter to firmly brace the gun and easily aim with stability by being held against the user's shoulder when shooting the gun, and helps to counter muzzle rise by transmitting recoil straight into the shooter's body. The tiller of a crossbow is functionally the equivalent of the stock on a gun. History and etymology The term stock in reference to firearms dates to 1571 is derived from the Germanic word ''Stock'', meaning tree trunk, referring to the wooden nature of the gunstock. Early hand cannons used a simple stick fitted into a socket in the breech end to provide a handle. The modern gunstock shape began to evolve with the introduction of the arquebus, a matchlock with a longer barrel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trench Gun
A combat shotgun is a shotgun issued by militaries for warfare. The earliest shotguns specifically designed for combat were the trench guns or trench shotguns issued in World War I. While limited in range, the multiple projectiles typically used in a shotgun shell increase the probability of hitting a target at close quarters. History While the sporting shotgun traces its ancestry back to the fowling piece, which was a refinement of the smoothbore musket, the combat shotgun bears more kinship to the shorter blunderbuss. Invented in the 16th century by the Dutch, the blunderbuss was used through the 18th century in warfare by the British, Austrian, Spanish (like the Escopeteros Voluntarios de Cadiz, formed in 1804, or the Compañía de Escopeteros de las Salinas, among others) and Prussian regiments, as well as in the American colonies. As use of the blunderbuss declined, the United States military began loading smaller lead shot (buckshot) in combination with their larger ...

M-LOK
M-LOK, for Modular Lock, is a firearm Rail Integration System, rail interface system developed and patented by Magpul Industries. The license is free-of-charge, but subject to an approval process. M-LOK allows for direct accessory attachment onto the "negative space" (hollow slot) mounting points, and is a competing standard to VLTOR's open sourced KeyMod system for replacing the ubiquitous Picatinny rail in some applications. Both M-LOK and KeyMod enable the user to have a slimmer, lighter, smoother and more fenestration (architecture), fenestrated handguard/Forearm (firearm component), fore-end with accessories and gadgets mounted only where needed as compared to a Picatinny handguard, which typically has whole length rail slots, resulting in a heavier weight, bulkier handguard and poorer Gun barrel, barrel ventilation, resulting in the barrel overheating more quickly. The M-LOK system can be seen as an evolution of the Magpul Original Equipment (MOE) system, but the two are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vertical Forward Grip
A vertical forward grip or foregrip is a vertical pistol grip mounted on the fore-end of a long-barrel firearm, designed for grasping by the frontal support hand (or "off hand"). Use Forward grips aid in the maneuverability of the firearm, since the natural angle of a person's outstretched hand is more oriented to grasping objects at a vertical angle, rather than a horizontal one perpendicular to the body. Foregrips can decrease accuracy in precision rifle shooting if the shooter tends to "muscle the weapon". Vertical foregrips can have features located inside the inner diameter, such as a deployable bipod inside the grip's housing. The grip may also have a tactical light and the control switches molded into the grip's assembly. Other designs may contain storage space for spare parts, spare batteries for optics, weapon lights, or small first aid gear. Some designs may have a bottom that threads on with an O-ring to make this storage compartment watertight. Stubby grip A ... [...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) or night-vision goggle (NVG), is an Optoelectronics, optoelectronic device that allows visualization of images in low levels of light, improving the user's night vision. The device enhances Available light, ambient visible light and converts Infrared#Regions within the infrared, near-infrared light into visible light which can then be seen by humans; this is known as I2 (Image intensifier, image intensification). By comparison, viewing of infrared thermal radiation is referred to as Thermography, 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 an optional mounting system. Many NVDs also include a protective sacrificial lens, mounted over the front/Objective (optics), objective lens to prevent damage by environmental hazards, while some incorporat ...

Laser Sight
A laser sight is a device attached or integral to a firearm to aid target acquisition. Unlike Telescopic sight, optical and Iron sights, iron Sight (device), sights where the user looks through the device to aim at the target, laser sights project a beam onto the target, providing a visual reference point. Although Laser, lasers in the Visible spectrum, visible part of the spectrum are most common, invisible infrared (IR) lasers may be used in conjunction with a Night-vision device, night vision device. As they are offset from the barrel, laser sights need to be Sighting in, zeroed in, much like a conventional sight, so that the beam intercepts the Predicted impact point, point of impact at a chosen distance. Devices may include one or both types of laser, with some models also incorporating a rangefinder, flashlight, or IR illuminator. Laser sights may be attached to the existing sighting mechanism, the trigger guard, via a Rail system (firearms), rail system, or can be integrate ...

Tactical Light
A tactical light or weapon light is a flashlight used in conjunction with a firearm to aid low-light target identification, allowing the user to simultaneously aim a weapon and illuminate the target. Tactical lights can be handheld or mounted to the weapon with the light beam parallel to the bore. Tactical lights can also serve as a non-lethal weapon, used to temporarily blind and disorient targets or, in the case of a large handheld flashlight, to be used as a blunt weapon. Features particularly associated with tactical lights include shock resistance, reliability, lightweight construction and powerful, long-lasting batteries, and high light intensity. Tactical lights may have optional filters to produce colored light, to not attract bugs, or may emit only infrared radiation for use with night vision equipment. A laser sight may also be added to a weapon-mounted tactical light. Handheld lights Handheld lights are generally restricted to use with handguns, as long guns such a ...

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 and Greek root , 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, but can a ...

M26 Modular Accessory Shotgun System
The M26-MASS (Modular Accessory Shotgun System) is a shotgun configured as an underbarrel ancillary weapon attachment mounted onto the handguard of a service rifle, usually the M16/ M4 family of the United States Armed Forces, essentially making the host weapon a combination gun. It can also be operated as a stand-alone shotgun by attachment to a pistol grip/collapsible buttstock module. Rollout commenced in 2013, replacing the Mossberg 500 shotguns in service. Development The M26-MASS is a lightweight underbarrel shotgun configured to be secured to a main rifle, developed by C-More Systems and manufactured by Vertu Corporation and originally marketed toward special operations forces. It attracted the interest of soldiers being deployed to Afghanistan who wanted a lightweight system that could eliminate the need to carry additional weapons. The M26-MASS had been in development at the U.S. Army's Soldier Battle Lab since the late 1990s. The idea was to provide soldier ...
