Adcor A-556
The ADCOR A-556 is an assault rifle based on the M16/M4 series. It is produced by the Adcor Defense Company and was one of the contenders in the US Army Individual Carbine Competition to replace the M4 Carbine. History In 2005, Adcor Defense was contracted by Colt to produce upper receivers for the M4 Carbine. Adcor was able to produce 1,000 uppers per day, compared to 450 uppers per day that Colt was able to manufacture. After years of production, Adcor Defense decided to improve upon the weapon. They claimed it was not a “new and improved” AR, but a patented revolutionary gas piston system with other key features that set it apart from all other M4-type rifles. Testing In early 2010, Adcor sent the ADCOR A-556 rifle to H.P. White Laboratory, known for small arms and ammunition research, development, and testing, to test the reliability of the design. Testing took place from March to April. 6,000 rounds were fired in 120 round cycles, and the guns were lubricated an ...

Minute 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 used in astro ...

ArmaLite AR-10 Derivatives
ArmaLite, or Armalite, is an American small arms engineering company, formed in the early 1950s, in Hollywood, California. Many of its products, as conceived by chief designer Eugene Stoner, relied on unique foam-filled fiberglass butt/stock furniture, and a composite barrel using a steel liner inside an aluminum sleeve, including the iconic AR15/M16 family. While the original ArmaLite ceased business in the 1980s, the brand was revived in 1996, by Mark Westrom. Originating as the light firearms division of Fairchild Engine and Airplane Corporation, ArmaLite was formally incorporated in 1954. Stoner's first design, the AR-1 Parasniper (dating from 1952), was relatively unsuccessful. However, in 1956, when ArmaLite competed in a contest for an aircrew survival rifle, its AR-5 and AR-7 designs were put into production and adopted by elements of the US military. The following year, ArmaLite also competed for the contract for a new main US combat rifle, in the NATO standard 7.62 mm ...

FN SCAR
The FN SCAR (Special Operations Forces Combat Assault Rifle) is a family of gas-operated short-stroke gas piston automatic rifles developed by Belgian manufacturer FN Herstal (FN) in 2004. It is constructed with modularity for the United States Special Operations Command (SOCOM) to satisfy the requirements of the SCAR competition. This family of rifles consist of two main types. The SCAR-L, for "light", is chambered in 5.56×45mm NATO and the SCAR-H, for "heavy", is chambered in 7.62×51mm NATO. Both are available in ''Close Quarters Combat'' (''CQC''), ''Standard'' (''STD''), and ''Long Barrel'' (''LB'') variants. In early 2004, United States Special Operations Command (USSOCOM) issued a solicitation for a family of Special Operations Forces Combat Assault Rifles, the so-called SCAR, designed around two different calibers but featuring high commonality of parts and identical ergonomics. The SCAR system completed low rate initial production testing in June 2007. After some de ...

Adaptive Combat Rifle
The Adaptive Combat Rifle (ACR) is a modular assault rifle designed by Magpul Industries of Austin, Texas, and known initially as the Masada. In late January 2008, Bushmaster Firearms International entered into a licensing agreement with Magpul whereby Bushmaster would take over production, future development, and sales of the Masada. It was then known as the Bushmaster ACR. However, Remington Arms is contracted to manufacture the rifle for the US military and US law enforcement agencies, in which it is known as the Remington ACR. Hence, Remington Arms is responsible for the selective fire version of the ACR, while Bushmaster Firearms International is responsible for the semi-automatic only version. The Remington ACR was one of the weapons displayed to U.S. Army officials during an invitation-only Industry Day on November 13, 2008. The goal of the Industry Day was to review current carbine technology prior to writing formal requirements for a future replacement for the M4 Car ...

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 ...

Individual Carbine
The Individual Carbine was a competition to select the planned successor to the M4 carbine in the United States Army. The U.S. Army conducted an open competition for a carbine to replace the M4. This competition was for the Army only—the United States Marine Corps and other branches chose to stay with current weapons in service. The proposal was passed before the Joint Requirements Oversight Council in August 2010, and the Army was to solicit submissions from the small arms industry by the end of that year. The competition was open to all manufacturers. However, Phase II testing reduced the field down to six rifles. The competition was intended to provide an evaluation of the full range of weapons available. Presolicitation notice W15QKN-11-R-F003 was posted January 31, 2011. Complete results of the competition and selection of a new carbine were expected before FY 2013. However, the competition was cancelled in June 2013.

Colt's Manufacturing Company
Colt's Manufacturing Company, LLC (CMC, formerly Colt's Patent Firearms Manufacturing Company) is an American firearms manufacturer, founded in 1855 by Samuel Colt and is now a subsidiary of Czech holding company Colt CZ Group. It is the successor corporation to Colt's earlier firearms-making efforts, which started in 1836. Colt is known for the engineering, production, and marketing of firearms, most especially between the 1850s and World War I, when it was a dominating force in its industry and a seminal influence on manufacturing technology. Colt's earliest designs played a major role in the popularization of the revolver and the shift away from earlier single-shot pistols. Although Samuel Colt did not invent the revolver concept, his designs resulted in the first very successful ones. The most famous Colt products include the Colt Walker, made in 1847 in the facilities of Eli Whitney Jr., the Colt Single Action Army or Peacemaker, the Colt Python, and the Colt M1911 p ...

M4 Carbine
The M4 carbine (officially Carbine, Caliber 5.56 mm, M4) is a 5.56×45mm NATO, gas-operated, magazine-fed carbine developed in the United States during the 1980s. It is a shortened version of the M16A2 assault rifle. The M4 is extensively used by the United States Armed Forces, with decisions to largely replace the M16 rifle in United States Army (starting 2010) and United States Marine Corps (USMC) (starting 2016) combat units as the primary infantry weapon and service rifle. The M4 has been adopted by over 60 countries worldwide, and has been described as "one of the defining firearms of the 21st century". Since its adoption in 1994, the M4 has undergone over 90 modifications to improve the weapon's ergonomics and modularity, including: the M4A1, which strengthened the barrel and removed the burst-fire option; the SOPMOD, an accessory kit containing optical attachments; and the underbarrel M203 grenade launcher. In April 2022, the U.S. Army selected the SIG MCX SPE ...
