The original ArmaLite/Colt AR-15 was a selective-fire prototype submitted for consideration as a military infantry rifle, and is distinguished from later civilian-model AR-15 and AR-15A2 rifles marketed by Colt Firearms.

The "AR" in AR-15 comes from the ArmaLite name, not "assault rifle" as is commonly believed; ArmaLite's AR-1, AR-5, and some subsequent models were bolt action rifles, and there are shotguns and pistols whose model numbers also include the "AR" prefix.[1] ArmaLite sold its rights to the AR-10 and AR-15 to Colt in 1959. Colt marketed the AR-15 rifle to various military services around the world, including the U.S. Air Force, Army, and Marine Corps. The AR-15 was eventually adopted by the United States military under the designation M16. However, Colt continued to use the AR-15 trademark for its semi-automatic variants (AR-15, AR-15A2) marketed to civilian and law-enforcement customers. The original AR-15 was a very lightweight weapon, weighing less than 6 pounds with empty magazine, though later heavy-barrel versions of the civilian AR-15 can weigh upwards of 8.5 lbs. Today the civilian-model AR-15 and its variations are manufactured by many companies and have captured the affection of sport shooters and police forces around the world due to their low cost, accuracy, and modularity. (Please refer to the M16 for a more complete history of the development and evolution of the AR-15 and derivatives.) The trademark "AR15" or "AR-15" is registered to Colt Industries, which maintains that the term should only be used to refer to their products. Other manufacturers make AR-15 clones marketed under separate designations, although colloquially, these are sometimes also referred to by the term "AR-15". Some revolutionary or otherwise notable features of the AR-15: Aircraft grade aluminum receiver Modular design allows for a variety of accessories and makes repair easier Small caliber, accurate, high velocity round Synthetic stock and grips do not warp or splinter Front sight adjustable for elevation Rear sight adjustable for windage and range Wide array of optical devices available in addition to or as replacements of ironsights A direct impingement gas system Semi-automatic and automatic variants of the AR-15 are effectively identical in appearance. Automatic variants have a rotating selective fire switch, allowing the operator to select between three modes: safe, semi-automatic, and either automatic or three round burst, depending on model. Civilian AR-15 models usually do not have three-round burst or automatic settings on the fire selector (e.g., Bushmaster Firearms. In semi-automatic only variants, the selector only rotates between safe and semi-automatic. [edit] Operating mechanism An M16 MagazineThe mechanism of operation for the rifle is known as direct gas impingement. Gas is tapped from the barrel as the bullet moves past a gas port located under the rifle's front sight base. The gas rushes into the port and down a gas tube located above the barrel. The gas tube runs from the front sight base into the AR-15's upper receiver. Here, the gas tube telescopes into a “gas key?which accepts the gas and funnels it into the bolt carrier. The movement of gas into the bolt carrier forces the bolt and carrier in opposite directions. As the bolt carrier moves towards the butt of the gun, the bolt begins to turn and unlock from the barrel extension. Once the bolt is fully unlocked it begins rearward movement along with the bolt carrier. The cam pin is responsible for the bolt's rotation as it follows a groove cut into the carrier that twists and forces the bolt to unlock. Once the bolt is unlocked, the bolt carrier and bolt continue to move towards the butt of the gun and the chambered casing is extracted and ejected out the side of the upper receiver. A return spring located behind a buffer then pushes the bolt carrier back towards the chamber. A groove machined into the upper receiver traps the cam pin and prevents it and the bolt from rotating into a closed position. The bolt's locking lugs then push a fresh round out of the magazine, up the feed ramps and into the chamber. As the bolt's locking lugs move past the barrel extension, the cam pin is allowed to twist into a pocket milled into the upper receiver. This twisting action follows the groove cut into the carrier and forces the bolt to twist and “lock?into the barrel’s extension. [edit] Variants The AR15 rifle is available in a wide range of configurations from a number of manufacturers. These configurations range from short carbine-length models with features such as adjustable length stocks and optical sights, to heavy barrel models. Aftermarket upper receivers that incorporate barrels of different weights and lengths, and handle different caliber ammunition, abound for this rifle. They are very easily installed, due to the rifle's modular design. These calibers include (in caliber size order): .22 Long Rifle .204 Ruger 5.56 ?45 mm NATO .223 Remington 6 x 45mm 6.5 Grendel (.264 cal) 6.8 SPC (.270 cal) .300 Whisper 7.62x39mm 9mm Parabellum .45 ACP .45 Bushmaster .458 SOCOM .50 AE .50 Beowulf .50 BMG When installing a new complete upper receiver, particularly one designed to handle a different caliber of ammunition (i.e. other than .223 Remington or 5.56 x 45 mm NATO), some modification to the contents of the lower receiver may also be required, depending on the particular conversion. For example, a conversion to 9mm typically would involve the installation of a magwell block (to accommodate a typical 9mm magazine, such as Uzi or Colt SMG), replacing the .223 hammer with one designed for 9mm ammunition, and depending on your original stock, replacing the buffer, action spring and stock spacer for those designed for your new 9mm AR-15 configuration. Earliest models had a 1:14 rate of twist, which was changed to 1:12 for original 55 grain (3.6 g) bullets. The 1:14 rate of twist showed to be unstable in colder temperatures. Most newer configurations use 1:9 and 1:7 twist rates. There is much controversy and speculation as to how differing twist rates affect ballistics and terminal performance with varying loads, but heavier projectiles tend to perform better with faster rifling rates. Additionally, the various non .223 / 5.56 calibers have their own particular twist rate. Standard issue magazines are 20 or 30 round double column magazines, traditional box magazines also exist in 40 and 45 round capacities, and usable magazines have been constructed from a variety of materials including steel, aluminum, and high-impact plastics. Drum magazines with 90 and 100 round capacities also exist, such as Beta C-Mags. Low-capacity magazines, usually of a 5 or 10 round capacity, are available to comply with some areas' legal restrictions, hunting and because larger magazines can inhibit shooting from a benchrest. [edit] Legal status in the United States In the United States, variants with certain features such as collapsible stocks, flash suppressors, and bayonet lugs were prohibited for sales to civilians during the period 1994-2004 by the Violent Crime Control and Law Enforcement Act of 1994, under the provision known as the Assault Weapons Ban. Those that were manufactured with those features were stamped, "Restricted Military/Government/Law Enforcement/Export Only" as well as the accompanying high capacity magazines. Since the expiration of the Federal AWB in September of 2004,[2] these features are now legal in most states.[3] The 2000 Assault Weapons ban in the state of California sparked a renewed interest in the AR-15 rifle. It is estimated that some 60,000 California Legal AR-15s are in existence in that state.[citation needed] Replacing the Lower Receiver of a standard AR-15 with one that has a fixed (10 round) magazine (see below) will render the firearm "California legal", and able to utilize banned features such as a telescoping stock and pistol grip. The magazine is not detachable, so to load the rifle the shooter must pull the rear takedown pin, hinge the upper receiver on the front takedown pin, and load the now exposed magazine either with a stripper clip or by hand, then close. Popular lower receivers for this purpose are manufactured by Stag Arms, Fulton Armory, Dane Armory, Mega, and Ameetec. By California law if the magazine requires a tool to remove it, that changes the classification of the firearm. A tool called the "Bullet Button" is gaining in popularity: the bullet button works by replacing the magazine release button with a hollow shell that protrudes a short distance from the lower; the shooter must then push the inset pin to activate the mag release, doing so requires a tool e.g., a bullet, hence the name. Stag makes a lower receiver called the STAG-15 which is considered an "off-list" receiver by the CA DOJ and is legal. As of December 2006, Doublestar, Stag Arms, CMMG, and MEGA all qualify as "off-list" lowers in the state of CA. There is also one model made by Colt, the CAR-A3 HBAR Elite, that was never banned by name, and thus still legal to own in California provided it has the correct configuration. This receiver can be made into a full rifle if the following requirements are met: the receiver has a fixed magazine with no more than 10 cartridges - in which case the rifle may have pistol grips, folding or collapsing stocks, etc.; or, the receiver may have a detachable magazine but may not possess any sort of attachment such as pistol grips, folding or collapsing stocks, etc. [edit] Concerns With the plethora of manufacturers of complete weapons and aftermarket barrels, there is a potential hazard associated with chamber specifications. Both civilian (SAAMI) specification .223 Remington and 5.56 mm NATO are available, though both chambers typically accept both types of ammunition, the firing of military specification ammunition in civilian specification chambers can produce chamber pressures greater than the barrel is designed to handle.[4] Military specification chambers typically have a more open throat area producing less pressure and can handle both types of ammunition. A few AR15 manufacturers (such as Rock River Arms) incorporate the use of a hybrid chamber specification known as the "Wylde" chamber, which provides for SAAMI-like accuracy while allowing for the safe use of military specification ammunition (5.56 NATO), the type of chamber, manufacturer, and rifling twist in inches is typically found stamped into the barrel in front of the front sight assembly. An additional point of concern in the design is the inertial firing pin, a lightweight firing pin rides in a channel inside the bolt unrestrained, when the bolt locks forward during loading, the firing pin typically rides forward and impacts the chambered round's primer. In military specification ammunition and quality civilian ammunition, this is not normally enough to fire the round and only leaves a small "ding" on the primer, with more sensitive primers or improperly seated primers, this can cause a slamfire during loading.[5] As in many small caliber firearms, it is possible to rupture the barrel of an AR15 if it is fired with water in the bore, after submersion or if it is suspected water may be in the barrel, it is recommended that the weapon be unloaded, pointed down, and the charging handle pulled to the rear to allow it to drain.[citation needed] [edit] See also M4 Carbine M16 SR-47 C7 Bushmaster M4 Type Carbine [edit] Manufacturers ArmaLite Bushmaster Colt Manufacturing Company DPMS Panther Arms High Standard Les Baer Custom Olympic Arms Rock River Arms Stag Arms Smith & Wesson Lewis Machine and Tool Co.

April 14, 2009 Reviewer:  Flint from ,     This gun is a great begginer gun, good for just plinking around the yard or if you just want to have some fun with your friends, but if you want to start seriously airsofting and you are still new to it but you know you want to, go get a JG M4 S-System, its a great gun, but overall this one is still good for only $80 Pros. Accurate Light (Can be a con for some people) FPS, great for only a $80 gun Cons Everything is basically plastic The sites that are suppose to be adjustable arent, but I probaly got a lemon I think it deserves 4 out of 5 for a good price and a good gun.

Was this review helpful to you?   0 of 0 people found the following review helpful:   Well R-6E June 4, 2008 Reviewer: Aaronius from Hereford, AZ United States   I gotta say, I am really impressed.  You CAN NOT beat this weapon for the price!  It's got a solid feel, good weight, and shoots strong.  One complaint is the battery placement, which is a real pain and nowhere near tactical.  Also, the sights are plastic and as a result the weapon can't be sighted accurately.  So you better be good with Kentucky windage.   Overall, it is above average for the price and a great weapon.
