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 ...

Melvin Johnson
Melvin Maynard Johnson Jr. (August 6, 1909 – January 9, 1965), nicknamed Maynard Johnson, was an American designer of firearms, lawyer, and United States Marine Corps officer. Biography Born into an affluent Boston, Massachusetts, family, he was commissioned into the Marine Corps Reserve in 1933 as a Second Lieutenant and completed Harvard Law School in 1934. Johnson designed a recoil-operated rifle ( M1941 Johnson rifle) while serving for the Marines as an observer at the Army's Springfield Armory in 1935. Johnson received four U.S. patents on various design features. He also designed the Johnson Light Machine Gun, derived from the M1941 rifle, which was used in limited numbers during World War II and the M1947 Johnson auto carbine, also derived from the M1941 rifle and M1941 light machine gun. In 1942, he co-authored ''Weapons for the Future'', a book in The Infantry Journal series. Charles T. Haven of the Army Ordnance Corps was the other contributor. Johnson worked ...

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 rimles ...

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 ...

M1941 Johnson Machine Gun
The M1941 Johnson Light Machine Gun, also known as the ''Johnson'' and the ''Johnny gun'', was an American recoil-operated light machine gun designed in the late 1930s by Melvin Johnson. It shared the same operating principle and many parts with the M1941 Johnson rifle and the M1947 Johnson auto carbine. Design The M1941 light machine gun was designed by a Boston lawyer and captain in the Marine Corps Reserve named Melvin Johnson Jr. His goal was to build a semi-automatic rifle that would outperform the M1 Garand the US Army had adopted. By late 1937, he had designed, built, and successfully tested both a semi-automatic rifle and a prototype light machine gun. Each shared a significant number of physical characteristics and common parts, and both operated on the principle of short recoil with a rotating bolt. He took the parts of other guns, switching them out and creating the M1941 light machine gun. Johnson's curved, single-column magazine attached to the left side of the r ...

M1 Garand
The M1 Garand or M1 rifleOfficially designated as U.S. rifle, caliber .30, M1, later simply called Rifle, Caliber .30, M1, also called US Rifle, Cal. .30, M1 is a semi-automatic rifle that was the service rifle of the U.S Army during World War II and the Korean War. The rifle is chambered for the .30-06 Springfield cartridge and is named after its Canadian Americans, Canadian-American designer, John Garand. It was the first standard-issue autoloading rifle for the United States. By most accounts, the M1 rifle performed well. General George S. Patton called it "the greatest battle implement ever devised". The M1 replaced the bolt-action M1903 Springfield as the U.S.' service rifle in 1936, and was itself replaced by the selective fire, selective-fire M14 rifle on March 26, 1958. Pronunciation Sources differ on the pronunciation of the M1 Garand. Some, such as General Julian Hatcher, Julian Hatcher's ''The Book of the Garand'' (1948), give , identical to the pronunciation of Joh ...

M1941 Johnson Rifle
The M1941 Johnson Rifle is an American short-recoil operated semi-automatic rifle designed by Melvin Johnson prior to World War II. Although the M1941 was used in limited numbers by the US Marines during the Second World War, it unsuccessfully competed with the contemporary M1 Garand rifle. Design The M1941 rifle used the energy from recoil to cycle the rifle. As the bullet and propellant gases move down the barrel, they impart force on the bolt head which is locked to the barrel. The barrel, together with the bolt, moves a short distance rearward until the bullet leaves the barrel and pressure in the bore drops to safe levels. The barrel then stops against a shoulder allowing the bolt carrier to continue rearward under the momentum imparted by the initial recoil stage. The rotating bolt, with eight locking lugs, would then unlock from the chamber as cam arrangement rotates and unlocks the bolt to continue the operating cycle. The Johnson rifle utilized a two-piece stock and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Model 45A
The Model 45A was a .30 caliber bullpup battle rifle/light machine gun developed by the United States Army in the Philippines in 1945. The weapon existed in prototype or mockup form, but never entered production. The rifle was sparsely documented until annotated photographs of the rifle were found in the archives of the United States Army Signal Corps. Design The Model 45A utilized the magazine from the M1918 Browning Automatic Rifle. Rather than iron sights, it featured an integral scope. Its purpose is unclear, but it is alternately described as a "experimental .30 caliber light machine gun (LMG)" or a "field expedient .30 cal."

M1946 Sieg Automatic Rifle
The Sieg automatic rifle was a bullpup automatic rifle designed by Chief Gunner's Mate James E. Sieg of the US Coast Guard. The weapon was chambered in the .30-06 round, fed from 20 round magazines and capable of firing around 650–700 RPM on full automatic. A two-finger double trigger selected between semiautomatic and fully automatic fire. The barrel came with a unique muzzle compensator that could be turned off for use with a flash hider or grenade launcher without interfering with the installation of a bayonet. Recoil gently threw the barrel of the Sieg rifle downward, not upward. When tested at Fort Benning, it had effective results. The compensator was extremely effective; it also enabled the user to fire the rifle with one hand. Sieg obtained a patent for his compensator in 1948, as USPTO 2451514.

30-06 Springfield Semi-automatic Rifles
3 (three) is a number, numeral and digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious or cultural significance in many societies. Evolution of the Arabic digit The use of three lines to denote the number 3 occurred in many writing systems, including some (like Roman and Chinese numerals) that are still in use. That was also the original representation of 3 in the Brahmic (Indian) numerical notation, its earliest forms aligned vertically. However, during the Gupta Empire the sign was modified by the addition of a curve on each line. The Nāgarī script rotated the lines clockwise, so they appeared horizontally, and ended each line with a short downward stroke on the right. In cursive script, the three strokes were eventually connected to form a glyph resembling a with an additional stroke at the bottom: ३. The Indian digits spread to the Caliphate in the 9th ...

Firearms By Melvin Johnson
A firearm is any type of gun designed to be readily carried and used by an individual. The term is legally defined further in different countries (see Legal definitions). The first firearms originated in 10th-century China, when bamboo tubes containing gunpowder and pellet projectiles were mounted on spears to make the portable fire lance, operable by a single person, which was later used effectively as a shock weapon in the Siege of De'an in 1132. In the 13th century, fire lance barrels were replaced with metal tubes and transformed into the metal-barreled hand cannon. The technology gradually spread throughout Eurasia during the 14th century. Older firearms typically used black powder as a propellant, but modern firearms use smokeless powder or other propellants. Most modern firearms (with the notable exception of smoothbore shotguns) have rifled barrels to impart spin to the projectile for improved flight stability. Modern firearms can be described by their caliber ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
