The L64 (also called the Enfield Individual Weapon) was an intermediate calibre British bullpup layout prototype assault rifle developed in the 1970s. At one time it was known as the 4.85 Individual Weapon, a reference to the calibre of the bullet it fired.
The British Army had considered bullpup designs with intermediate calibre rounds in the 1950s, and officially adopted one of these as .280 British in 1951 in the EM-2 and Taden gun. However, US intransigence during NATO standardization efforts, and Winston Churchill's interest in standards above all, led to the adoption of the 7.62×51mm NATO round. This was significantly more powerful than the .280, and could not be easily adapted to the existing weapons. Instead, the British and Canadian armies adopted the L1A1 SLR, a licensed version of the FN FAL, itself originally designed for the .280.
During the 1960s the US found that, as the British had suggested, the 7.62 NATO round was far too powerful to be used in a fully automatic rifle. After considerable wrangling, the US Army eventually adopted the M16 rifle, firing the .223 Remington cartridge of much lower power than even the .280. With standardization "broken", the British Army once again started researching lighter rounds in the 1970s. These efforts suggested that a round of similar weight as the M16s, but firing a smaller diameter bullet, would offer the same recoil patterns while having much better penetration and ballistics. The result was the .190-inch (4.85 mm) round fitted in "necked down" but otherwise standard 5.56 mm cartridges from the M16.
The Royal Small Arms Factory developed a rifle to fire the new round. The new L64/65 "Individual Weapon" was outwardly similar to the earlier EM-2, but adopted a firing mechanism very similar to ArmaLite's latest AR-18 design, which was manufactured in Britain under license by the Sterling Armaments Company from 1975 to 1983. The first examples were available in 1972.
By 1976, NATO was ready to standardize on a small calibre round, and testing of the various rounds head-to-head started in 1977. As designed, the British round performed well, but NATO concluded that the Fabrique Nationale's entry based on the 5.56 mm, the "SS-109" gave the "best all-round performance" and was selected.
The L64 pattern was later developed into the SA80 family of weapons, which entered service with the UK in the mid-1980s.
The L64/65 is a gas operated, 4.85mm calibre bullpup assault rifle. It uses an AR18 type operation with an SVT40 type gas piston. The SUSAT sight is robust and reliable.
A carbine is a long gun that has a barrel shortened from its original length. Most modern carbines are rifles that are compact versions of a longer rifle or are rifles chambered for less powerful cartridges.
The 5.56×45mm NATO is a rimless bottlenecked centerfire intermediate cartridge family developed in the late 1970s in Belgium by FN Herstal. It consists of the SS109, L110, and SS111 cartridges. On 28 October 1980, under STANAG 4172, it was standardized as the second standard service rifle cartridge for NATO forces as well as many non-NATO countries. Though they are not identical, the 5.56×45mm NATO cartridge family was derived from and is dimensionally similar to the .223 Remington cartridge designed by Remington Arms in the early 1960s.
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 FN FAL is a battle rifle designed in Belgium by Dieudonné Saive and manufactured by FN Herstal and others since 1953.
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.
An automatic rifle is a type of autoloading rifle that is capable of fully automatic fire. Automatic rifles are generally select-fire weapons capable of firing in semi-automatic and automatic firing modes. Automatic rifles are distinguished from semi-automatic rifles in their ability to fire more than one shot in succession once the trigger is pulled. Most automatic rifles are further subcategorized as battle rifles or assault rifles.
A magazine, often simply called a mag, is an ammunition storage and feeding device for a repeating firearm, either integral within the gun or externally attached. The magazine functions by holding several cartridges within itself and sequentially pushing each one into a position where it may be readily loaded into the barrel chamber by the firearm's moving action. The detachable magazine is sometimes colloquially referred to as a "clip", although this is technically inaccurate since a clip is actually an accessory device used to help load ammunition into a magazine or cylinder.
The ArmaLite AR-18 is a gas-operated assault rifle chambered for 5.56×45mm NATO ammunition. The AR-18 was designed at ArmaLite in California by Arthur Miller, Eugene Stoner, George Sullivan, and Charles Dorchester in 1963 as an alternative to the Colt AR-15 design, a variant of which had just been selected by the U.S. military as the M16. A semi-automatic version known as the AR-180 was later produced for the civilian market. While the AR-18 was never adopted as the standard service rifle of any nation, its production license was sold to companies in Japan and the United Kingdom, and it is said to have influenced many later weapons such as the British SA80, the Singaporean SAR-80 and SR-88, the Belgian FN F2000, the Japanese Howa Type 89 and the German Heckler and Koch G36.
A battle rifle is a service rifle chambered to fire a fully powered cartridge.
The Special Purpose Individual Weapon (SPIW) was a long-running United States Army program to develop, in part, a flechette-firing "rifle", though other concepts were also involved. The concepts continued to be tested under the Future Rifle Program and again in the 1980s under the Advanced Combat Rifle program, but neither program resulted in a system useful enough to warrant replacing the M16.
The EM-2, also known as Rifle, No.9, Mk.1 or Janson rifle, was a British assault rifle. It was briefly adopted by British forces in 1951, but the decision was overturned very shortly thereafter by Winston Churchill's incoming government in an effort to secure NATO standardisation of small arms and ammunition. It was an innovative weapon with the compact bullpup layout, built-in carrying handle and an optical sight.
The origins of the modern British military rifle are within its predecessor the Brown Bess musket. While a musket was largely inaccurate over 100 yards (91 m), due to a lack of rifling and a generous tolerance to allow for muzzle-loading, it was cheap to produce and could be loaded quickly. The use of volley or mass firing by troops meant that the rate of fire took precedence over accuracy.
The .280 British was an experimental rimless bottlenecked intermediate rifle cartridge. It was later designated 7 mm MK1Z, and has also been known as .280/30, .280 Enfield, 7 mm FN Short and 7×43mm.
An intermediate cartridge is a rifle/carbine cartridge that has significantly greater power than a pistol cartridge but still has a reduced muzzle energy compared to fully powered cartridges, and therefore is regarded as being "intermediate" between traditional rifle and handgun cartridges.
A STANAG magazine or NATO magazine is a type of detachable firearm magazine proposed by NATO in October 1980. Shortly after NATO's acceptance of the 5.56×45mm NATO rifle cartridge, Draft Standardization Agreement (STANAG) 4179 was proposed in order to allow NATO members to easily share rifle ammunition and magazines down to the individual soldier level. The U.S. M16 rifle's magazine proportions were proposed for standardization. Many NATO members, but not all, subsequently developed or purchased rifles with the ability to accept this type of magazine. However, the standard was never ratified and remains a "Draft STANAG".
The Bushmaster M17S is a semi-automatic bullpup rifle that was manufactured by Bushmaster Firearms International from 1992 until 2005.
The TADEN was a British experimental light and medium machine gun firing the .280 in (7 mm) intermediate cartridge. Alongside the bullpup EM-2 rifle design, it formed part of a proposal to reequip the British Army with new small arms which would use a round smaller than the .303 inch which was shown to be impractical for use in a modern assault rifle. The name comes from the designer, Harold Turpin ('T') at the Armament Design Establishment ('AD') and Enfield ('EN').
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 L1A1 Self-Loading Rifle (SLR), also known by the initial Canadian designation C1, or in the U.S. as the "inch pattern" FAL, is a British version of the Belgian FN FAL battle rifle. The L1A1 was produced under licence and adopted by the armed forces of the United Kingdom, Australia, Canada, India, Jamaica, Malaysia, New Zealand, Rhodesia and Singapore.
The 4.85×49mm is an experimental intermediate firearm cartridge made by the United Kingdom for the Individual Weapon Project, which became the SA80 series of small arms.
