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").
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. [1] Foregrips can decrease accuracy in precision rifle shooting if the shooter tends to "muscle the weapon". [2]
Vertical foregrips can have features located inside the inner diameter, such as a deployable bipod inside the grip's housing. [3] 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.[ citation needed ]
A shorter version is referred to as a "stubby grip" and is primarily intended to keep the shooter's hand from moving forward of the muzzle. [2]
Angled forward grips can provide similar functionality to vertical forward grips. They differ in that a vertical foregrip is more useful for "driving" the weapon, while an angled foregrip is more effective at pulling the weapon into the shooter's shoulder while keeping the offhand wrist in a comfortable and manageable position, which helps with accuracy. Some angled foregrips are designed to be used with the C Clamp grip which allows good pointability (as vertical foregrips allow) as well as better accuracy because of the shooter's more firm purchase on the weapon. [4] One such popular product is the MagPul Dynamics AFG, or Angled Fore Grip. This allows the operator to lay the palm of their hand onto the grip while pushing the thumb down on the top of the gun.[ citation needed ]
The legality of vertical foregrips on pistols in the United States is unclear. In the United States, firearms are categorized by the National Firearms Act and firearms manufactured with specific features are subject to restrictions and controls. In the case of a vertical forward grip on a pistol, the law does not explicitly define such a feature as belonging to any category.[ citation needed ]
In May 1993, in response to legal action brought by the Bureau of Alcohol, Tobacco, and Firearms (ATF), the South Carolina District Court's finding of fact concluded that a pistol modified with the addition of vertical fore grips was still a pistol and not any other weapon device. [5] Following this, the ATF dropped their charges and the case was not tried; as such no precedent was set.[ citation needed ]
In an open letter sent to Federal Firearms Licensees in April 2006, the ATF stated their interpretation of the law: that installing a vertical forward grip on a handgun is the same as manufacturing an Any Other Weapon (AOW) category firearm and subject to registration and taxation, with significant penalties for manufacturing or possessing such an unregistered weapon. [6]
The ATF has stated that angled grips do not make an AOW from a handgun. [7]
A firearm is any type of gun that uses an explosive charge and is designed to be readily carried and used by an individual. The term is legally defined further in different countries.
A machine pistol is an autoloading pistol that is capable of fully automatic fire, including stockless handgun-style submachine guns.
In firearm designs, the term single-shot refers to guns that can hold only a single round of ammunition inside and thus must be reloaded manually after every shot. Compared to multi-shot repeating firearms ("repeaters"), single-shot designs have no moving parts other than the trigger, hammer/firing pin or frizzen, and therefore do not need a sizable receiver behind the barrel to accommodate a moving action, making them far less complex and more robust than revolvers or magazine/belt-fed firearms, but also with much slower rates of fire.
A muzzle brake or recoil compensator is a device connected to, or a feature integral to the construction of, the muzzle or barrel of a firearm or cannon that is intended to redirect a portion of propellant gases to counter recoil and unwanted muzzle rise. Barrels with an integral muzzle brake are often said to be ported.
The National Firearms Act (NFA), 73rd Congress, Sess. 2, ch. 757, 48 Stat. 1236 was enacted on June 26, 1934, and currently codified and amended as I.R.C. ch. 53. The law is an Act of Congress in the United States that, in general, imposes an excise tax on the manufacture and transfer of certain firearms and mandates the registration of those firearms. The NFA is also referred to as Title II of the federal firearms laws, with the Gun Control Act of 1968 ("GCA") as Title I.
A semi-automatic pistol is a handgun that automatically ejects and loads cartridges in its chamber after every shot fired. Only one round of ammunition is fired each time the trigger is pulled, as the pistol's fire control group disconnects the trigger mechanism from the firing pin/striker until the trigger has been released and reset.
A gunsmith is a person who repairs, modifies, designs, or builds guns. The occupation differs from an armorer, who usually replaces only worn parts in standard firearms. Gunsmiths do modifications and changes to a firearm that may require a very high level of craftsmanship, requiring the skills of a top-level machinist, a very skilled woodworker, and even an engineer. Gunsmiths perform factory-level repairs and renovations to restore well-used or deteriorated firearms to new condition. They may make alterations to adapt sporting guns to better fit the individual shooter that may require extensive modifications to the firearm's stocks and metal parts. Repairs and redesigns may require fabrication and fitting of unavailable parts and assemblies constructed by smiths themselves. Gunsmiths may also renew metal finishes or apply decorative carvings or engravings to guns. Many gun shops offer gunsmithing service on the premises.
A firearm is said to fire from an open bolt or open breech if, when ready to fire, the bolt and working parts are held to the rear of the receiver, with no round in the chamber. When the trigger is actuated, the bolt travels forward, feeds a cartridge from the magazine or belt into the chamber, and fires that cartridge in the same movement. Like any other self-loading design, the action is cycled by the energy released from the propellant, which sends the bolt back to the rear, compressing the mainspring in readiness for firing the next round. In an open-bolt gun firing semi-automatically, the bolt is caught and held at this point by the sear after each shot; and in automatic open-bolt fire, it's caught and held in this manner whenever the trigger is released. In contrast to this, in closed-bolt guns, the trigger and sear do not affect the movement of the bolt directly.
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.
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.
On a firearm or other tools, a pistol grip is a distinctly protruded handle underneath the main mechanism, to be held by the user's hand at a more vertical angle, similar to how one would hold a conventional pistol.
The Jatimatic is a Finnish 9×19mm Parabellum submachine gun developed in the late 1970s and early 1980s by Jali Timari. The submachine gun made its debut in 1983. The Jatimatic was manufactured in very limited numbers initially by Tampereen Asepaja Oy of Tampere and later—Oy Golden Gun Ltd. The firearm was designed primarily for police, security forces and armored vehicle crews. It was never adopted into service by the Finnish Defence Forces, although the later GG-95 PDW version was tested by the FDF in the 1990s.
Thompson/Center Arms was an American firearms company based in Springfield, Massachusetts. The company was best known for its line of interchangeable-barrel, single-shot pistols and rifles. Thompson/Center also manufactured muzzle-loading rifles and was credited with creating the resurgence of their use in the 1970s.
The HK4 is a pocket pistol, first introduced by Heckler & Koch in either 1964 or 1967. It was distinctive for allowing shooters to swap barrels chambered for different cartridges without tools and for having a durable but light hard-anodized aluminum-alloy frame.
The Hi-Point Model JHP is a polymer-framed, semi-automatic, blowback-operated pistol manufactured by Hi-Point Firearms.
AMD-65 is a Hungarian-manufactured licensed variant of the venerable selective fire AKM rifle for use by that nation's armored infantry and paratrooper ("descent") units within the Hungarian Defence Forces. The rifle's design is suited for outdoor use as an infantry rifle but can also be used from within the confines of an armored vehicle as a fire support weapon. This is possible due to the side-folding stock of shaft design that makes it more compact. The 12.6-inch barrel is also relatively short for the 7.62×39mm cartridge. The operating mechanism does not require a gas expansion chamber at the muzzle, as in the AKS-74U to ensure reliable functioning, but does use a specially designed muzzle brake.
A pistol is a type of handgun, characterised by a barrel with an integral chamber. The word "pistol" derives from the Middle French pistolet, meaning a small gun or knife, and first appeared in the English language c. 1570 when early handguns were produced in Europe. In colloquial usage, the word "pistol" is often used as a generic term to describe any type of handgun, inclusive of revolvers and the pocket-sized derringers.
Title II weapons, or NFA firearms, are designations of certain weapons under the United States National Firearms Act (NFA).
Muzzle rise, muzzle flip or muzzle climb refers to the tendency of a firearm's or airgun's muzzle to rise up after firing. It more specifically refers to the seemingly unpredictable "jump" of the firearm's muzzle, caused by combined recoil from multiple shots being fired in quick succession. It has an adverse effect on maintaining accuracy with using automatic weapons or rapid-firing semi-automatic firearms, as a moving muzzle can throw off the shooter's aim, causing subsequent shots to miss the intended target.
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.
