Quoted:
Haha no no. I mean what does the a mean and the r And the 15. Example: ak47. A= avtomat. K= kalasnikov. 47= model of 1947 ARMALITE model 15 ETA: Armalite sold the right to the AR-15 to Colt in 1959, Colt still owns the trademark (is that the right word) for the AR-15. I am no hostorical expert on the design but I am pretty sure what I said is true. |

K= kalasnikov. 47= model of 1947 the 15 is just the next number in the series that is used. just like the military M14, M15(a M14 to replace the BAR), the M16, etc. the M stands for model, and the number is just the classification in the subcatagory. Carbine : m1, m2, m3, m4, M4A1 Rifle: M1, M14, m15, m16, M16a1, M16a2, M16A3, M16a4 |

ar15= armalite rifle 15. first designed by armalite who went under and colt bought the name. the armalite name was then bought out by another company(eagle arms??) but only colt can still use AR-15 for their rifles, everyone else is a veriant (ie : bushmaster xm-15)
M4 - military version of the stoner design with a 14.5" barrel, carbine gas, m4 profile bbl. A1,2,3,4 designates upper reciever type(a2 or flattop a3) and firecontrol combo(3 burst of FA) m16 is the 20" bbl version, gvt profile bbls are lw under handguards and Hbar out front. a1,2,3,4 dictates upper reciever, fcg, and rail/handgard combo. any additions or corrections are more than welcome but i think i got the basics. BTW, for the m16/4 they are made mainly by colt and FN, and some other companies have been contracted here and there. I believe these include Bushy, LMT, and i know kac does some military stuff (m110) |

ARMALITE’S DEVELOPMENTS. The following firearms were developed or produced by ArmaLite. Other AR family firearms were designed by Eugene Stoner, but not developed by ArmaLite, and aren’t listed.
AR-1 (1954 and before) “Parasniper” rifle, using either military or sporting calibers, including 7.62 NATO. The Parasniper is a very high quality, lightweight bolt action rifle designed as a fine sporting rifle or for special military sniping operations. The AR-1 began life at ArmaLite’s first location in Hollywood, California. It broke new ground by using foam filled fiberglass stock and an anodized aluminum barrel with a thin steel liner. A variety of receivers were to be used, with a Remington action common. The rifle with scope weighs a modest 6 pounds. Very few AR-1s were made. AR-2 The model T-35 designed by George Sullivan. No additional information about this rifle is available at this time. AR-3 The AR-3 is a 7.62mm semiautomatic rifle designed by Eugene Stoner and brought to ArmaLite when he was hired. It uses the multi-lug bolt of Stoner’s later designs, but features a conventionally shaped stock. AR-4 Described as a “Can Gun” by David R. Hughes in his book “M-16 Rifle and it’s Cartridge.” No other information is currently available. AR-5 (1954-55) A bolt action, .22 Hornet survival rifle adopted by the Air Force in 1956. It weighed a mere 2 ¾ pounds. It distinguishing characteristic was the ability to detach the barrel from the action, and the action from the stock, and place both within the stock. With the buttcap replaced, the rifle would float. The government specification for the MA-1 called for a second, .22 long rifle barrel to be attached outside the stock. After adopting the AR-5 as the MA-1, the Air Force failed to follow through with a purchase. The main effect of the AR-5 was to whet ArmaLite’s appetite for government business. It led to development of the AR-7. AR-7 (1959-60) The AR-7 Explorer was the first commercial item to be put into production by the ArmaLite Division of Fairchild. This rifle is the civilian version of the Air Force adopted AR-5 Survival Rifle. The AR-7 fires the popular .22 long rifle rimfire cartridge. The rifle disassembles without the use of tools and stows inside its plastic butt stock. The AR-7 weighs as little as 2 ¾ pounds and will float in water, either assembled or in the stowed configuration. The action is semi-automatic and is fed from an eight-round magazine. The AR-7 was sold to Charter Arms in 1973. It has been in intermittent production since. ArmaLite reintroduced it in early 1998. AR-8 (no date known, but evidently 1954 or 1955 due to the series number) A .270 caliber bolt action rifle. AR-9 (1955) A 12-guage semiautomatic shotgun experimented with in 1955. Like the AR-17, it featured an aluminum receiver and barrel, and plastic furniture. AR-10 (1955-56) Intended to serve as the basic infantry rifle, in caliber 7.62mm NATO. The AR-10 was conceived by Eugene Stoner, and was tested by US. Ordnance as early as 1956 at Springfield Armory. It was licensed to Artillerie Inrichtingen in Holland in 1957, and with the AR-15 was licensed to Colt’s Patent Firearms Company in 1959. The AR-10 combined a number of previous features with a new gas system patented by Stoner. In the Stoner system, gas ported off the barrel travels down a tube back into the upper receiver, and into the bolt carrier. It enters an expansion chamber, where it expands and drives the carrier to the rear. The rearward movement of the carrier transferred by a cam pin riding in a curved path and engaging the bolt, forces the bolt to rotate to unlock. (Common reports that the Stoner system is copied from the Swedish Ljungman system are incorrect: the Ljungman system has a tube carrying gas ported off the barrel, but the tube simply directs the gas into a cavity in the top of the carrier to blow the carrier to the rear.) The AR-10 was later improved with lessons learned from the early AR-15s. The new model was designated the AR-10a. It was produced in prototype form only. Artillerie Inrichtingen produced a small number of semiautomatic-only sporting versions of the AR-10 as the “AR-10s.” The AR-10 was intended to compete with Springfield’s M-14 rifle and FN’s FAL. It was, unfortunately, a bit too late. Although it showed great promise during tests, it required a bit of further development. It was too late. The major effect of the AR-10 was to lead to Army interest in a similar rifle of smaller caliber. That rifle became the AR-15 AR-10B (1994-96) An update of the AR-10 placed in production in 1996. The AR-10 was fielded in very small numbers: less than 6,000. Despite the small numbers, the fame of the rifle grew to take the rifle to cult status. It was, after all, the more powerful and rare precursor to the AR-15. Civilian shooters took great pains to recover used AR-10s from the surplus market and convert them to civilian rifles by means of new, semi-automatic only receivers. The popularity of the AR-10 rifle led Knight’s Manufacturing and, later, ArmaLite to return it to production. Knight entered the market first with an AR-10 derivative called the SR-25. The SR-25 combined features of the AR-10 with as many parts of the AR-15 as could be used. The ArmaLite AR-10B was then patterned on the SR-25 rifle. To improve function, the ArmaLite AR-10B employs far fewer parts from the M-15/M-16 rifles than the SR-25, and uses a modified version of the proven M-14 rifle magazine. ArmaLite AR-10B production surpassed Dutch and ArmaLite/Fairchild AR-10 and AR-10a production in 2000. AR-11 (date unknown, but evidentally between 1954 and 1956) A .222 caliber semiautomatic rifle similar to the AR-3. Reputed to have a high cyclic rate that, combined with the conventional stock from, climbed rapidly during firing. AR-12 (date unknown) A stamped, 7.62mm version if the AR-10 predating the AR-16. AR-13 (date unknown) Hughes describes this as a multiple-barrel “Hypervelocity Anti-Aircraft Machine Gun” using the squeezebore system. The shot pattern to be generated was called the “Cloud of Crud.” This was a concept gun only, no prototypes were developed. AR-14 (date unknown) Sporting versions of the AR-10 in calibers 7.62mm, .243, and .358 calibers using a Monte Carlo type stock. AR-15 (1956-1959) Basic infantry rifle using ArmaLite developed .223 caliber ammunition. The AR-15 was licensed to the Colt’s Patent Firearms Manufacturing Company in January 1959. The U.S. Air Force completed tests of the AR-15 in January 1961. The Air Force procured 8,500 rifles in 1961 and standardized the AR-15 in 1963. 85,000 rifles were purchased in that year. The military designation of the AR-15 is M-16. The Army also ordered 85,000 rifles in 1963. An additional 35,000 were ordered in 1964, 100,000 in 1965, and 100,000 in 1996. These rifles were initially issued primarily to combat troops in the Dominican Republic and to Special Forces, Airborne, helicopter crews, Air Commando and other special category troops in Vietnam. The M-16 was type classified standard A in 1965 and became the military’s basic service rifle. AR-16 (1959-60) The AR-16 is a basic infantry rifle of 7.62mm NATO caliber. The primary reason for the development of the AR-16 was to produce a weapon with the performance capabilities of the AR-10/AR-15 series, but at a greatly reduced production cost. Another consideration was to make a rifle less difficult to produce in countries without advanced technological resources. Although the AR-16 didn’t enter production, elements of its design influenced the 1995 design of the AR-10B. AR-17 (1956-62) The AR-17 is an innovative semi-automatic shotgun featuring a hard-anodized aluminum receiver and barrel and a plastic stock. The barrel was equipped with replaceable chokes. The AR-17 was called the “Golden Gun” due to the color of the aluminum components. Two thousand sets of parts for the AR-17 were produced, but only 1,200 guns were sold. The AR-17 never met commercial success; it was semi-automatic, but held only two shots. It was lightweight, but was marketed to trap and skeet shooters, who normally fire many shots per day. AR-18 (1963-65) Just as the AR-16 is basically a sheet metal version of the AR-10, the AR-18 is a sheet metal version of the AR-15. The AR-18 was an effort to correct the 1959 mistake of selling the AR-15 to Colt’s. As the AR-15 became successful, ArmaLite needed a rifle that could compete in the same market. The AR-18 is a .223 caliber, gas operated, 6.9 pound rifle equipped with a folding stock designed by Arthur Miller and L. James Sullivan. It is capable of both full and semi-automatic fire. The AR-18 uses steel stampings instead of allow forgings, this simplifying manufacture and greatly reducing production costs. The main functional differences include the use of a Tokarev style sliding gas cylinder under the handguards that avoided violating the Stoner gas system patent that was sold to Colt’s. The new system had the advantage of keeping powder residue out of the action. The second difference was the use of dual operating springs on rods in the upper receiver. By avoiding the spring and buffer in the stock used with the AR-15, the AR-18 could be equipped with a folding stock. This allowed the AR-18 to be folded to a compact size for paratroop operations. The AR-18 was produced in a semiautomatic version, the AR-180. AR-19 (1995) The AR-19 was intended to be a .223 caliber straight-pull rifle. Early development work was dropped to concentrate on the AR-10B rifle. No hardware was produced. The project is currently dormant. AR-20 (1999) AR-20 was the initial designation of ArmaLite’s .50 caliber rifle (see below). The designation was changed to AR-50 to emphasize the caliber of the rifle. This is the first case of non-sequential model designations. AR-21 Not used. AR-22 (1998-present) The AR-22 is a Blank Firing Device for the Mk 19 Mod 4 40mm Grenade Machine-gun, and is designed for training or testing the Mk 19. It employs the standard 7.62mm NATO Blank to cycle the Mk 19. The AR-22 was conceived by CW4 John Miller, Ohio National Guard, and designed by George Reynolds. Reynolds brought it to ArmaLite when he began work on the ArmaLite AR-50 rifle (see below). AR-23 (1998-2000) The AR-23 is a Sub-Caliber Training Device for the Mk 19 Mod 4 Grenade Machine-gun. It employs a special tracer cartridge designed to follow the ballistic arc of the 40mm grenade. The AR-23 was conceived by CW4 John Miller, OHNG (RET), and designed by George Reynolds. Like the AR-22, Reynolds brought the AR-23 to ArmaLite when he began work on the ArmaLite AR-50 rifle. The AR-23 was successfully test fired n the Mk 19 Mod 4, but the unforgiving balance between the energy available in the special cartridges and the energy required by the Mk 19 led Reynolds to recommend dropping the project late in 2000. AR-30 (1999-present) The AR-30 is a smaller version of the AR-50 (below), featuring that rifle’s unique metallic stock system. It was initially prototyped as a .308 caliber bolt action rifle, but current plans call for it to be introduced first in magnum calibers. AR-31 (1999-present) In process. AR-50 (1998-99) ArmaLite’s normal pattern of sequential model numbers was altered for the AR-50. The model number reflects the rifle’s caliber. The AR-50 is chambered for the .50 caliber Browning Machine Gun cartridge, and is capable of being built to accept the more powerful Russian 12.7mm cartridge. It features a unique stock made largely of aluminum. The forend, in particular, is interesting. It is extruded with a V cross section that mates with an octagonal receiver. This allows precise, repeatable bedding with no hand labor. The buttstock includes a vertically adjustable butt pad and adjustable cheek rest. The initial AR-50 departs from ArmaLite’s normal trend towards lightweight rifles: it weighs 41 pounds. It is intended for the commercial market, where the weight adds comfort when firing the powerful cartridge. Shorter and lighter versions are in development. |
