The McCrudden light machine rifle is a light machine gun of Australian origin. [1]
The McCrudden light machine rifle was invented by ex-Australian serviceman John Charles Raginald McCrudden (known as Reg) following his discharge from the AIF in 1917. It is believed there are only two surviving examples of this interesting weapon, one being held in the Pattern Room in Leeds, England. The other McCrudden Light Machine Rifle Mk1 is on extended loan to the Power House Museum exhibition in Sydney, Australia. [2] [3]
McCrudden's first hand-built prototype was believed to have been manufactured at an engineering workshop in Randwick, Sydney. McCrudden and his guns traveled from Sydney to Jervis Bay for an audience with Commodore J S Dumaresq and Lt Cmdr Burgh. He was received favorably and recommendations were made that he should take the gun to England for assessment by the British War Office, Dumaresq forwarding a favorable report in light of the Navy's pending trials to select a weapon to replace the Lewis Gun. Following Dumaresq's advice McCrudden took his designs to England where he had additional weapons made by Kingsway Manufacturing Company Ltd in London.
According to a press report in the Daily Telegraph of August 6, 1921 McCrudden alleged that his gun was foolproof, with only seven moving parts and had the advantage of having a variable rate of fire adjustable to ‘fire one or 800 rounds per minute as easily as one can operate a throttle’. In addition the gun could also be easily converted to water cooling for sustained fire.
Both the Mk and the later Miki suffered chronic misfeeds due to the internal design of the gun and the location of the magazine at the side of the gun. Had McCrudden relocated the magazine to the top, he may well have had a successful design.
A submachine gun (SMG) is a magazine-fed automatic carbine designed to fire handgun cartridges. The term "submachine gun" was coined by John T. Thompson, the inventor of the Thompson submachine gun, to describe its design concept as an automatic firearm with notably less firepower than a machine gun. As a machine gun must fire rifle cartridges to be classified as such, submachine guns are not considered machine guns. The submachine gun was developed during World War I (1914–1918) as a close quarter offensive weapon, mainly for trench raiding. At its peak during World War II (1939–1945), millions of submachine guns were made for assault troops and auxiliaries whose doctrines emphasized close-quarter suppressive fire. New submachine gun designs appeared frequently during the Cold War, especially among special forces, covert operation commandos and mechanized infantrymen. Submachine gun usage for frontline combat decreased in the 1980s and 1990s, and by the early 21st century, submachine guns have largely been replaced by assault rifles, which have a longer effective range, have increased stopping power, and can better penetrate the helmets and body armor used by modern soldiers. However, they are still used by security forces, police tactical units, paramilitary and bodyguards for close-quarters combat because they are "a pistol-caliber weapon that's easy to control, and less likely to overpenetrate the target".
A squad automatic weapon (SAW), also known as a section automatic weapon or light support weapon (LSW), is a man-portable automatic firearm attached to infantry squads or sections as a source of rapid direct firepower. Weapons fulfilling this role can be light machine guns, or modified selective-fire rifles fitted with a heavier barrel, bipod and a belt/drum-fed design.
The SA80 is a British family of 5.56×45mm NATO service weapons used by the British Army. The L85 Rifle variant has been the standard issue service rifle of the British Armed Forces since 1987, replacing the L1A1 Self-Loading Rifle. The prototypes were created in 1976, with production of the A1 variant starting in 1985 and ending in 1994. The A2 variant came to be as the result of a significant upgrade in the early 2000s by Heckler & Koch and remains in service as of 2024. The A3 variant was first issued in 2018 with several new improvements.
The Thompson submachine gun is a blowback-operated, selective-fire submachine gun, invented and developed by Brigadier General John T. Thompson, a United States Army officer, in 1918. It was designed to break the stalemate of trench warfare of World War I, although early models did not arrive in time for actual combat.
A bullpup firearm is one with its firing grip located in front of the breech of the weapon, instead of behind it. This creates a weapon with a shorter overall length for a given barrel length, and one that is often lighter, more compact, concealable, and more maneuverable than a conventionally configured firearm. Where it is desirable for troops to be issued a more compact weapon, the use of a bullpup configuration allows for barrel length to be retained, thus preserving muzzle velocity, range, and ballistic effectiveness.
The M1 carbine is a lightweight semi-automatic carbine that was issued to the U.S. military during World War II, the Korean War, and the Vietnam War. The M1 carbine was produced in several variants and was widely used by paramilitary and police forces around the world after World War II.
The STEN is a British submachine gun chambered in 9×19mm which was used extensively by British and Commonwealth forces throughout World War II and during the Korean War. The Sten paired a simple design with a low production cost, facilitating mass production to meet the demand for submachine guns.
The StG 44 is a German assault rifle developed during World War II by Hugo Schmeisser. It is also known by its early designations as the MP 43 and MP 44. The StG 44 was an improvement of an earlier design, the Maschinenkarabiner 42(H).
The Bren gun was a series of light machine guns (LMG) made by Britain in the 1930s and used in various roles until 1992. While best known for its role as the British and Commonwealth forces' primary infantry LMG in World War II, it was also used in the Korean War and saw service throughout the later half of the 20th century, including the 1982 Falklands War. Although fitted with a bipod, it could also be mounted on a tripod or be vehicle-mounted.
The Lewis gun is a First World War–era light machine gun. Designed privately in the United States though not adopted there, the design was finalised and mass-produced in the United Kingdom, and widely used by troops of the British Empire during the war. It had a distinctive barrel cooling shroud, and top-mounted pan magazine. The Lewis served until the end of the Korean War, and was widely used as an aircraft machine gun during both World Wars, almost always with the cooling shroud removed, as air flow during flight offered sufficient cooling.
The Chauchat was the standard light machine gun or "machine rifle" of the French Army during World War I (1914–18). Its official designation was "Fusil Mitrailleur Modele 1915 CSRG". Beginning in June 1916, it was placed into regular service with French infantry, where the troops called it the FM Chauchat, after Colonel Louis Chauchat, the main contributor to its design. The Chauchat in 8mm Lebel was also extensively used in 1917–18 by the American Expeditionary Forces (A.E.F.), where it was officially designated as the "Automatic Rifle, Model 1915 (Chauchat)". A total of 262,000 Chauchats were manufactured between December 1915 and November 1918, including 244,000 chambered for the 8mm Lebel service cartridge, making it the most widely manufactured automatic weapon of World War I. The armies of eight other nations—Belgium, Finland, Greece, Italy, Poland, Romania, Russia, and Serbia—also used the Chauchat machine rifle in fairly large numbers during and after World War I.
The Browning automatic rifle (BAR) is a family of American automatic rifles and machine guns used by the United States and numerous other countries during the 20th century. The primary variant of the BAR series was the M1918, chambered for the .30-06 Springfield rifle cartridge and designed by John Browning in 1917 for the American Expeditionary Forces in Europe as a replacement for the French-made Chauchat and M1909 Benét–Mercié machine guns that US forces had previously been issued.
The .45 Reising submachine gun was manufactured by Harrington & Richardson (H&R) Arms Company in Worcester, Massachusetts, USA, and was designed and patented by Eugene Reising in 1940. The three versions of the weapon were the Model 50, the folding stock Model 55, and the semiautomatic Model 60 rifle. Over 100,000 Reisings were ordered during World War II, and were initially used by the United States Navy, Marine Corps, and the United States Coast Guard, though some were shipped to Canadian, Soviet, and other allied forces to fight the Axis powers.
The Jarmann M1884 is a Norwegian bolt-action repeating rifle designed in 1878 adopted in 1884. The Jarmann's adoption, and subsequent modifications, turned the Norwegian Army from a fighting force armed with single-shot black-powder weapons into a force armed with modern repeating weapons firing smokeless ammunition. Several thousand were manufactured to equip the Norwegian Armed Forces in the 1880s, and it also saw some, though very limited, use in Sweden. The design is unique, and was the brainchild of Norwegian engineer Jacob Smith Jarmann. After the design had been phased out of the Norwegian Army, a number of the weapons were rebuilt as harpoon guns.
The Sterling submachine gun is a British submachine gun (SMG). It was tested by the British Army in 1944–1945, but did not start to replace the Sten until 1953. A successful and reliable design, it remained standard issue in the British Army until 1994, when it began to be replaced by the L85A1, a bullpup assault rifle.
The Fedorov Avtomat or FA is a select-fire infantry rifle and one of the world's first operational automatic rifles, designed by Vladimir Grigoryevich Fyodorov in 1915 and produced in the Russian Empire and later in the Russian Soviet Federative Socialist Republic. A total of 3,200 Fedorov rifles were manufactured between 1915 and 1925 in the city of Kovrov; the vast majority of them were made after 1920. The weapon saw limited combat in World War I, but was used more substantially in the Russian Civil War and in the Winter War. Some consider it to be an early predecessor or ancestor of the modern assault rifle.
The Mendoza RM2 was a light machine gun similar to the M1918 BAR manufactured in Mexico by Productos Mendoza, S.A. Rafael Mendoza have been producing machine guns for the Mexican Army since 1933 and all have been noted for their lightness, simplicity, ease of maintenance, and economic construction without sacrificing reliability.
The Huot Automatic Rifle was a Canadian World War I era light machine gun project.
An assault rifle is a select fire rifle that uses an intermediate-rifle cartridge and a detachable magazine. Assault rifles were first put into mass production and accepted into widespread service during World War II. The first assault rifle to see major usage was the German StG 44, a development of the earlier Mkb 42. While immediately after World War II, NATO countries were equipped with battle rifles, the development of the M16 rifle during the Vietnam War prompted the adoption of assault rifles by the rest of NATO. By the end of the 20th century, assault rifles had become the standard weapon in most of the world's armies, replacing full-powered rifles and submachine guns in most roles. The two most successful modern assault rifles are the AK-47 and the M16 designs and their derivatives.
The M249 SAW, formally the Light Machine Gun, 5.56 mm, M249, is the United States Armed Forces adaptation of the Belgian FN Minimi, a light machine gun manufactured by FN Herstal (FN).
