AR-15

    The ArmaLite AR-15 is a 5.56 mm assault rifle, powered by gas and powered from a magazine, which has a rotating bolt and a linear design. It was designed by Eugene Stoner, Leroy James Sullivan and Bob Fremont, from the AR-10 rifle. The AR-15 was designed from the start as a light assault rifle, which would fire a new cartridge with a small-caliber, high-speed bullet, which would allow soldiers to carry more ammunition.

    In 1959, ArmaLite sold its rights on AR-10 and AR-15 to Colt's Manufacturing Company due to financial difficulties. The Colt continued to produce the rifle under the Colt ArmaLite AR-15 brand and publicized it to various Armed Forces around the world. After several modifications (mainly the relocation of the cargo handle from under the carrying handle to the rear of the receiver), the redesigned new rifle was adopted by the United States Army as the M16 rifle, which entered production in March 1964. The Colt continued to use the trademark AR-15 for its series of semi-automatic rifles aimed at the civil and police market, known as Colt AR-15. The ArmaLite AR-15 was the forerunner of a variety of models of semi-automatic and assault rifles.

   Developed in 1956, the AR-15 owes its existence to studies conducted that proved that the best military cartridge would be similar to a .223 Remington high speed. On the basis of this analysis, the US Army requested the design of a 5.56 mm caliber rifle with an effective range of 500 meters, leaving the project in charge of Eugene Stoner. It was used in the Vietnam War by the United States. The standard AR-15 rifle accepts a wide variety of loaders with different capacities and has a pistol protruding from the cylinder head line, resulting in a highly adaptable and configurable rifle. 

    It can be equipped with accessories such as a bipod, retractable or folding heads, cannons with flame arresters and rail systems to add flashlights, laser pointers, telescopic sight, etc. It has a mechanism drawer with two sections, upper and lower, separated and easy to disassemble without tools. The upper section is considered as an isolated accessory and can be purchased from various suppliers. This is attractive for those who wish to acquire several upper sections in different calibers and exchange them, still using the same lower section. However, people should be aware of the configuration of the rifle, since there may be laws that restrict certain modifications (eg, in the United States).

    After the Second World War, the US Army began to look for an automatic rifle to replace the M1 Garand, the M1 / ​​M2 carbines, the M1918 BAR, the M3 "Grease Gun" and the Thompson.89 However, the first experiments with M1 Garand versions equipped with trigger mode selector proved to be disappointing. During the Korean War, the M2 carbine with selector replaced mainly the sub-machine gun in US service11 and became the most used carbine. However, the combat experience showed that the cartridge. Carbine was not very powerful. American weapon designers came to the conclusion that an intermediate power cartridge was necessary, recommending one to mount a small-caliber, high-speed bullet.

    However, retired American commanders who had faced fanatical enemies and experienced significant logistical problems during World War II and the Korean War, insisted that a single 7.62mm caliber cartridge be developed, which would not only be used by the new automatic rifle, but also by the new general-purpose machine gun that was being developed. This culminated in the development of the 7.62 x 51 OTAN cartridge. Then the US Army began testing several rifles to replace the obsolete M1 Garand. The T44E4 and heavier T44E5 of the Springfield Arsenal were essentially upgraded versions of the Garand modified to fire the new 7.62mm cartridge, while the Fabrique Nationale of Herstal sent its FN FAL with the designation T48. The ArmaLite entered the contest late, hastily sending several prototypes of the AR-10 in the fall of 1956 to the Springfield Arsenal to be tested. An AR-10 ArmaLite with its mounted bayonet, manufactured by Artillerie Inrichtingen (A.I.).

    The AR-10 had an innovative design that aligned the stock with the barrel, its cassette was made of forged aluminum alloy and its stock and forend were phenolic resin. It had simple raised aiming mechanisms, a large muzzle breaker / aluminum muzzle brake and an adjustable gas system. The final prototype had a mechanism drawer with two halves (lower and upper) joined with the usual hinge and disassembly pins, while the loading handle was on the mechanism drawer, under the carrying handle. For a rifle firing the 7.62 x 51 NATO cartridge, the AR-10 was very light, weighing just 3.10 kg unloaded. Initial comments from the Springfield Arsenal test team were favorable, some of the testers commenting that the AR-10 was the best light automatic rifle that was tested at Arsenal.

    Thank you , shared your blog
    The number one reason, in my opinion, to develop a new cartridge is to push heavy bullets and further dragging further and faster than the Legacy cartridge allows. Such projectiles have a high ballistic coefficient (BC) which means, in general, that they are better off against wind effects, maintaining speed, and maintaining downrange energy.

    Thank you share your information, Best Waterproof Monocular Telescope Buying a firearm is an investment. So, you must protect it from all kinds of issues. Environmental factors like dust, oil, and humidity can often cause the gunmetal to tarnish, rust, or corrode. So, clean it properly every time you use it. And if your gun gets wet while using it outdoors, dry it off immediately. Apart from that, always keep it safe from unauthorized access by kids or any other person, who are not allowed to stay near the gun or theft. To do this, you should invest in a gun vault or gun safe to keep it secured.
