David Marshall Williams
David Marshall Williams (November 13, 1900 – January 8, 1975) was an American firearms designer and convicted murderer who invented the floating chamber and the short-stroke piston. Both designs used the high-pressure gas generated in or near the breech of the firearm to operate the action of semi-automatic firearms like the M1 Carbine. Early life David Marshall Williams was born in Cumberland County, North Carolina, the son of James Claude Williams by his second wife, Laura Susan Kornegay. He was the eldest of seven children and the younger half brother of the five surviving children from the first marriage of James Claude Williams to Eula Lee Breece. James Claude Williams was a wealthy and influential landowner of hundreds of acres in and around Godwin, North Carolina. As a young boy, he worked on his family's farm. He was expelled from school during the eighth grade by Godwin School Principal H.B. Gaston and began work in a blacksmith shop. At the age of 15 he enlisted i ...

Cumberland County, North Carolina
Cumberland County is a county located in the U.S. state of North Carolina. As of the 2020 census, the population was 334,508, making it the fifth-most populous county in North Carolina. Its county seat is Fayetteville. Cumberland County is part of the Fayetteville, NC Metropolitan Statistical Area. History The county was formed in 1754 from Bladen County. It was named for Prince William Augustus, Duke of Cumberland (1721–1765), captain-general of the British army and victorious commander at the Battle of Culloden. In 1771 parts of Cumberland County, Johnston County, and Orange County were combined to form Wake County. In July 1784 the western part of Cumberland County became Moore County; the eastern part became Fayette County in honor of the Marquis de la Fayette, but the name Cumberland County was restored three months later. The county was represented as Fayette County in the North Carolina General Assembly of April 1784. In 1855 the northern part of Cumberland Cou ...

Machining
Machining is a process in which a material (often metal) is cut to a desired final shape and size by a controlled material-removal process. The processes that have this common theme are collectively called subtractive manufacturing, which utilizes machine tools, in contrast to '' additive manufacturing'' (3D printing), which uses controlled addition of material. Machining is a part of the manufacture of many metal products, but it can also be used on other materials such as wood Wood is a porous and fibrous structural tissue found in the stems and roots of trees and other woody plants. It is an organic materiala natural composite of cellulose fibers that are strong in tension and embedded in a matrix of ligni ..., plastic, ceramic, and composite material. A person who specializes in machining is called a machinist. A room, building, or company where machining is done is called a machine shop. Much of modern-day machining is carried out by Numerical control, computer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
22 Long Rifle
The .22 Long Rifle or simply .22 LR or 22 (metric designation: 5.6×15mmR) is a long-established variety of .22 caliber rimfire ammunition originating from the United States. It is used in a wide range of rifles, pistols, revolvers, smoothbore shotguns, and submachine guns. In terms of units sold it is by far the most common ammunition in the world today. Common uses include hunting and shooting sports. Ammunition produced in .22 Long Rifle is effective at short ranges, has little recoil, and is cheap to purchase, making it ideal for training. History American firearms manufacturer J. Stevens Arms & Tool Company introduced the .22 Long Rifle cartridge in 1887. The round owes its origin to the .22 BB Cap of 1845 and the .22 Short of 1857. It combined the case of the .22 Long of 1871 with a bullet, giving it a longer overall length, a higher muzzle velocity and superior performance as a hunting and target round, rendering the .22 Extra Long cartridges obsolete. The . ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M1919 Browning Machine Gun
The M1919 Browning is a .30 caliber medium machine gun that was widely used during the 20th century, especially during World War II, the Korean War, and the Vietnam War. The M1919 saw service as a light infantry, coaxial, mounted, aircraft, and anti-aircraft machine gun by the U.S. and many other countries. The M1919 was an air-cooled development of the standard US machine gun of World War I, the John M. Browning-designed water-cooled M1917. The emergence of general-purpose machine guns in the 1950s pushed the M1919 into secondary roles in many cases, especially after the arrival of the M60 in US Army service. The United States Navy also converted many to 7.62 mm NATO, and designated them Mk 21 Mod 0; they were commonly used on riverine craft in the 1960s and 1970s in Vietnam. Many NATO countries also converted their examples to 7.62 mm caliber, and these remained in service well into the 1990s, as well as up to the present day in some countries. Operation Loading ...

Caliber
In guns, particularly firearms, caliber (or calibre; sometimes abbreviated as "cal") is the specified nominal internal diameter of the gun barrel bore – regardless of how or where the bore is measured and whether the finished bore matches that specification. It is measured in inches or in millimeters. In the United States it is expressed in hundredths of an inch; in the United Kingdom in thousandths; and elsewhere in millimeters. For example, a "45 caliber" firearm has a barrel diameter of roughly . Barrel diameters can also be expressed using metric dimensions. For example, a "9 mm pistol" has a barrel diameter of about 9 millimeters. Since metric and US customary units do not convert evenly at this scale, metric conversions of caliber measured in decimal inches are typically approximations of the precise specifications in non-metric units, and vice versa. In a rifled barrel, the distance is measured between opposing lands or between opposing grooves; groove mea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
30-06 Springfield
The .30-06 Springfield cartridge (pronounced "thirty- aught-six" ), 7.62×63mm in metric notation, and called the .30 Gov't '06 by Winchester, was introduced to the United States Army in 1906 and later standardized; it remained in military use until the late 1970s. The ".30" refers to the caliber of the bullet in inches. The "06" refers to the year the cartridge was adopted, 1906. It replaced the .30-03, 6mm Lee Navy, and .30-40 Krag cartridges. The .30-06 remained the U.S. Army's primary rifle and machine gun cartridge for nearly 50 years before being replaced by the 7.62×51mm NATO and 5.56×45mm NATO, both of which remain in current U.S. and NATO service. It remains a very popular sporting round, with ammunition produced by all major manufacturers. History In the early-1890s, the U.S. military adopted the smokeless powder .30-40 Krag rimmed cartridge. The 1894 version of that cartridge used a round-nose bullet. Around 1901, the U.S. started developing an experimental r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Department Of War
The United States Department of War, also called the War Department (and occasionally War Office in the early years), was the United States Cabinet department originally responsible for the operation and maintenance of the United States Army, also bearing responsibility for naval affairs until the establishment of the Navy Department in 1798, and for most land-based air forces until the creation of the Department of the Air Force on September 18, 1947. The Secretary of War, a civilian with such responsibilities as finance and purchases and a minor role in directing military affairs, headed the War Department throughout its existence. The War Department existed from August 7, 1789 until September 18, 1947, when it split into the Department of the Army and the Department of the Air Force. The Department of the Army and Department of the Air Force later joined the Department of the Navy under the United States Department of Defense in 1949. History 18th century The Depar ...

45 ACP
The .45 ACP ( Automatic Colt Pistol) or .45 Auto (11.43×23mm) is a rimless straight-walled handgun cartridge designed by John Moses Browning in 1904, for use in his prototype Colt semi-automatic pistol. After successful military trials, it was adopted as the standard chambering for Colt's M1911 pistol. The round was developed due to a lack of stopping power experienced in the Moro Rebellion in places like Sulu. The issued ammunition, .38 Long Colt, had proved inadequate, motivating the search for a better cartridge. This experience and the Thompson–LaGarde Tests of 1904 led the Army and the Cavalry to decide that a minimum of .45 caliber was required in a new handgun. The standard issue military .45 ACP round uses a 230- grain (14.9 g) round nose projectile that travels at approximately 830 feet per second (250 m/s) when fired from a government-issue M1911A1 pistol. It operates at a relatively low maximum chamber pressure rating of , compared to for both 9 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M1911 Pistol
The M1911 (Colt 1911 or Colt Government) is a single-action, recoil-operated, semi-automatic pistol chambered for the .45 ACP cartridge. The pistol's formal U.S. military designation as of 1940 was ''Automatic Pistol, Caliber .45, M1911'' for the original model adopted in March 1911, and ''Automatic Pistol, Caliber .45, M1911A1'' for the improved M1911A1 model which entered service in 1926. The designation changed to ''Pistol, Caliber .45, Automatic, M1911A1'' in the Vietnam War era. Designed by John Browning, the M1911 is the best-known of his designs to use the short recoil principle in its basic design. The pistol was widely copied, and this operating system rose to become the preeminent type of the 20th century and of nearly all modern centerfire pistols. It is popular with civilian shooters in competitive events such as the International Defensive Pistol Association and International Practical Shooting Confederation. The U.S. military procured around 2.7 million M1911 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colt Ace
The Colt Ace or Colt Service Model Ace is a firearm that was designed to allow inexpensive and low-recoil practice while maintaining the feel of the military Model 1911 pistol. History While the Colt 1911 was chambered in the powerful .45 ACP cartridge, the externally similar Colt Ace was chambered for the far less powerful .22 LR cartridge. Accordingly, military, police, or civilian shooters could shoot the Ace without the recoil and expense of the 1911, but with similar ergonomics and sight picture. Except for the earliest models, the barrels of these guns are constructed with a hinged floating rear chamber that amplifies the recoil, cycling the heavy slide. The floating chamber can become fouled and stuck leading to poor feeding. When field stripping the Ace, the recoil spring is removed after removing the slide. The ejector may be removed before removing the barrel and the floating chamber must be aligned vertically to remove the barrel from the slide. Once the barrel is rem ...

Colt 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 pis ...
