HK SL8
The Heckler & Koch SL8 is a semi-automatic rifle manufactured by Heckler & Koch. It is the civilian version of the Heckler & Koch G36. The rifle fires the .223 Remington or 5.56×45mm NATO cartridge and feeds from a 10-, 20- or 30-round detachable magazine (depending on the variant of the rifle). Unlike earlier types of HK rifles, it is not a roller lock bolt but rather a lug-type rotating bolt system as seen on the AR-18. Design To adapt the G36 for the civilian market, its pistol grip and folding stock have been replaced by a fixed stock with a thumbhole. The receiver has also been modified to prevent the attachment of a folding stock. In addition, to comply with the Gun Control Act of 1968, SL8 rifles exported to the United States have been modified so that they will not accept staggered 20- and 30-round G36 magazines, only accepting single stack, 10-round magazines. Other modifications have been made to the SL8, including a lightened trigger pull, adjustable cheekpiece an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semi-automatic Rifle
A semi-automatic rifle is an autoloading rifle that fires a single cartridge with each pull of the trigger, and uses part of the fired cartridge's energy to eject the case and load another cartridge into the chamber. For comparison, a bolt-action rifle requires the user to cycle the bolt manually before they can fire a second time, and a fully automatic rifle fires continuously until the trigger is released. History The first design of a recoil-operated semi-automatic rifle is attributed to Ferdinand Mannlicher, who unveiled the design in 1885 based on work begun in 1883. Other non-gas operated semi-automatic models were the Model 85 and Mannlicher Models 91, 93 and 95 rifles. The designs were deeply flawed and never made past the conceptual/prototype stage due to issues inherent to the black powder used in their cartridges (based around the Austrian 11×58mmR M/77), such as insufficient velocity and excessive fouling; automatic firearms would only become feasible after smoke ...

223 Remington
The .223 Remington (designated as the 223 Remington by the SAAMI and 223 Rem by the CIP) is a rimless, bottlenecked rifle cartridge. It was developed in 1957 by Remington Arms and Fairchild Industries for the U.S. Continental Army Command of the United States Army as part of a project to create a small-caliber, high-velocity firearm. The .223 Remington is considered one of the most popular common-use cartridges and is currently used by a wide range of semi-automatic and manual-action rifles as well as handguns. History The development of the cartridge, which eventually became the .223 Remington, was linked to the development of a new lightweight combat rifle. The cartridge and rifle were developed by Fairchild Industries, Remington Arms, and several engineers working toward a goal developed by U.S. Continental Army Command (CONARC). Development began in 1957. A project to create a small-caliber, high-velocity (SCHV) firearm was created. Eugene Stoner of ArmaLite was al ...

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 ...

Magazine (firearm)
A magazine is an ammunition storage and feeding device for a repeating firearm, either integral within the gun (internal/fixed magazine) or externally attached (detachable magazine). The magazine functions by holding several cartridges within itself and sequentially pushing each one into a position where it may be readily loaded into the barrel chamber by the firearm's moving action. The detachable magazine is sometimes colloquially referred to as a " clip", although this is technically inaccurate since a clip is actually an accessory device used to help load ammunition into a magazine. Magazines come in many shapes and sizes, from tubular magazines on lever-action and pump-action firearms that may tandemly hold several rounds, to detachable box and drum magazines for automatic rifles and light machine guns that may hold more than one hundred rounds. Various jurisdictions ban what they define as "high-capacity magazines". Nomenclature With the increased use of semi-autom ...

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] |

Heckler & Koch G36
The Heckler & Koch G36 (Gewehr 36) is a 5.56×45mm assault rifle designed in the early 1990s by German weapons manufacturer Heckler & Koch as a replacement for the heavier 7.62×51mm G3 battle rifle. It was accepted into service with the ''Bundeswehr'' in 1997, replacing the G3.Woźniak, Ryszard. Encyklopedia najnowszej broni palnej – tom 2 G-Ł. Bellona. 2001. pp17-21. Since then, it has also been a popular export, and the G36 has seen active service in military and police units in several countries, including Germany, Spain, and the United Kingdom. The G36 is gas-operated and feeds from a 30-round detachable box magazine or 100-round C-Mag drum magazine. In 2012, the G36 was found to suffer from severe accuracy problems when the weapon overheated which prompted the search for a replacement. In 2017, the ''Bundeswehr'' launched the ''System Sturmgewehr Bundeswehr'', a program to find a replacement for the G36. The weapons put forth were the Heckler & Koch HK416, Heckler & ...

Blowback (arms)
Blowback is a system of operation for self-loading firearms that obtains energy from the motion of the cartridge case as it is pushed to the rear by expanding gas created by the ignition of the propellant charge. Several blowback systems exist within this broad principle of operation, each distinguished by the methods used to control bolt movement. In most actions that use blowback operation, the breech is not locked mechanically at the time of firing: the inertia of the bolt and recoil , relative to the weight of the bullet, delay opening of the breech until the bullet has left the barrel. A few locked breech designs use a form of blowback (example: primer actuation) to perform the unlocking function. The blowback principle may be considered a simplified form of gas operation, since the cartridge case behaves like a piston driven by the powder gases. Other operating principles for self-loading firearms include delayed blowback, blow forward, gas operation, and recoil operatio ...

Armalite AR-18
The ArmaLite AR-18 is a gas-operated assault rifle chambered for 5.56×45mm NATO ammunition. The AR-18 was designed at ArmaLite in California by Arthur Miller, Eugene Stoner, George Sullivan, and Charles Dorchester in 1963 as an alternative to the Colt AR-15 design, a variant of which had just been selected by the U.S. military as the M16. A semi-automatic version known as the AR-180 was later produced for the civilian market. While the AR-18 was never adopted as the standard service rifle of any nation, its production license was sold to companies in Japan and the United Kingdom, and it is said to have influenced many later weapons such as the British SA80,"It's especially interesting to note that the RSAF's later 5.56mm rifle, the SA-80, (later adopted as the L85) was nothing more than a bullpup version of the AR-180" the Singaporean SAR-80 and SR-88, the American Adaptive Combat Rifle, the Belgian FN F2000, the Japanese Howa Type 89 and the German Heckler and Koch G36. ...

Gun Control Act Of 1968
The Gun Control Act of 1968 (GCA or GCA68) is a U.S. federal law that regulates the firearms industry and firearms ownership. Due to constitutional limitations, the Act is primarily based on regulating interstate commerce in firearms by generally prohibiting interstate firearms transfers except by manufacturers, dealers and importers licensed under a scheme set up under the Act. The GCA was signed into law by President Lyndon B. Johnson on October 22, 1968, and is Title I of the U.S. federal firearms laws. The National Firearms Act of 1934 (NFA) is Title II. Both GCA and NFA are enforced by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). GCA repealed the Federal Firearms Act of 1938, though many of its provisions were reenacted as part of the GCA, which revised the FFA and its predecessor, the National Firearms Act of 1934 (NFA). History The bill was initially prompted by the assassination of U.S. President John F. Kennedy in 1963. The President was shot and ki ...
