SA80 (''Small Arms for 1980s'') is a family of related arms that include the British Army's standard combat Assault rifle. They were introduced to service in 1985, and will likely remain the primary infantry weapon until 2015. == Description == The SA80 family is made of three weapons, the L85 IW (''Individual Weapon''), the L86 LSW (''Light Support Weapon'') and the manually operated L98 CGP (''Cadet General Purpose''). All three are similar in most respects - they all fire the 5.56mm NATO round from a 30-round box magazine, and can mount the SUSAT (''Sight Unit; Small Arms; Trilux''), a 4x optical sight with a tritium-powered glowing pointer for limited night sighting as well as the CWS (Common Weapon Sight) - a ultraviolet night sight. Rifles issued to Combat Arms are equipped with the SUSAT, while rifles issued to Combat Support Arms and Combat Service Support Arms, and cadets, are equipped with a simple iron sight incorporating a carrying handle. LSWs for all Arms are issued with SUSATs. The weapons are designed in the bull-pup configuration with pistol grip foward of the magazine and the mechanism in the butt. This allows the use of a long, accurate barrel in a weapon with compact dimensions. The long barrel results in a particulary high muzzle velocity for an assault rifle. Combined with the free-floating nature of the heavy barrel and the optical performance of the SUSAT, this gives the weapon excellent accuracy. The LSW is a section (military unit)-level magazine-fed light machine gun. For this role it adds a bipod, buttstrap and rear pistol grip, and has a different design of handguard. Its longer barrel also improves muzzle velocity for longer effective range. The gun is otherwise identical to the basic L85 and the magazines and some internal parts are interchangeable. This weapon is now being supplemented by the FN Minimi, a box-fed weapon capable of longer bursts of fire. The CGP is broadly similar to the IW, but lacks a gas system and change lever. They were built in order to allow Cadets to train on a non-automatic version of the IW. The working parts are re-cocked by hand after each shot, using a large cocking handle. This is connected to the bolt by an external rod, and runs on a slide on the side of the body well forward of the working parts, making it far easier to use in the prone position than that of the IW or LSW (which, of course, do not require frequent manual recocking). == History == Royal Small Arms Factory developed the XL65 bull-pup rifle to fire the new .190" (4.85mm) round it had designed for submission to the NATO new cartridge selection trials announced in 1977. The 4.85mm round was a "necked down" but otherwise standard US 5.56mm cartridges from the M-16. It was unsuccessful and the 5.56mm SS109 round was accepted as NATO standard. The XL65 was essentially an AR-18 redesigned in a bull-pup configuration. (The AR-18 internals are also the basis for the Heckler und Koch G36 rifle). The SA80 was a further development rechambered to fire the 5.56mm round. == Criticisms == The initial version of the weapon quickly gained a poor reputation for dependability and durability in trials. Lack of a guard for the magazine ejector button meant the magazine would sometimes fall out while walking. The walls of the receiver were so thin that the bolt could be stopped from moving by squeezing it, and was prone to being dented. Occasionally the top cover would fly open while the weapon was being fired and needed to be taped down. Many of these problems were rectified with the A1 version which became the main production model, but its reputation had been made. However, reports of high incidences of jamming continued, attributed to a cocking handle that sometimes deflected empty cartridges back into the ejector port, and sensitivity to dirt. Reports by H&K have also suggested that over-zealous cleaning had a detrimental effect on the rifle. This includes both using abrasives on parts not suited to them, as well as simple over-cleaning. The rifle and LSW are both criticised for their weight; approximately 1kg heavier than other 5.56mm weapons (however this reduces recoil and increases accuracy). Much of the weight is in the butt of the weapon requiring a small weight in the front handguard to balance the weapon. The safety switch requires the use of the trigger finger (rather than thumb on the M16 (rifle) and G36), and the ejection port and reciprocating bolt handle on the right-hand side of the weapon means it is impossible to fire from the left shoulder as in a normal firing position this would rest against the side of the firer's left cheek. ===L85A2=== In 1997 the SA80 was dropped from NATO's list of approved weapons, following which an upgrade programme was started. In 2000 Heckler and Koch, at that time owned by Royal Ordnance were contracted to fix the problems. Two hundred thousand SA80s were remanufactured at a cost of £400 each producing the A2 variant of the weapon. By 2002 the upgraded versions were deployed in first line formations. The upgrade involved replacement of many internal parts and has greatly increased reliability. In March 2005 the L85A2 was put through it's paces against the M16 M4 AK47 AN-94 and G36 rifles, it outperformed all of them in accuracy (even without the SUSAT's) and reload speed (physically changing magazine on the move and static), and all but the AK47 in reliability on multiple terrain, weather and climatic senarios. Showing up both the M-16 and the new M4 as dangerously out of touch. Making weight it's only real drawback hence the carbine variant has also been redeveloped with a 20-round magazine, and will enter service as a self-defence weapon for British Army tank crews during 2005. Many specialist UK formations, such as the Special Air Service, Royal Marine Special Boat Squadron, Royal Marine Brigade Recce Group (Formerly Mountain and Arctic Warfare Cadre), use the Diemaco C-7 or C-8 (Canadian licence-built copies of the M4 carbine) over the SA80 due to its lower weight, despite having only two-thirds the effective range of the SA80. This is because of their different combat requirements. The Heckler and Koch upgrades are a matter of some debate; the UK Ministry of Defence could have ordered 100,000 G36 rifles for the same cost. In a further Heckler and Koch upgrade a number of L85A2 rifles are now being fitted with the HK AG36 40mm grenade launcher in a configuration similar to the M203. ==Specifications== === L85 Individual Weapon === * Calibre 5.56 mm * Weight 4.98 kg (with loaded magazine and optical sight) * Length 785 mm * Barrel Length 518 mm * Muzzle Velocity 940 m/s * Feed 30 round magazine * Effective Range 300m individual, 600m section * Cyclic Rate of Fire 610-775 rounds per minute === L86 Light Support Weapon === * Calibre 5.56 mm * Weight 6.58 kg (with loaded magazine and optical sight) * Length 900 mm * Barrel Length 646 mm * Muzzle Velocity 970 m/s * Feed 30 round magazine * Effective Range 800m * Cyclic Rate of Fire 610-775 rounds per minute. ==External links== * [http://www.army.mod.uk/equipment/pw/pw_sa80.htm British Army SA80 page] * [http://world.guns.ru/assault/as22-e.htm Modern Firarms - L85A1] * [http://www.quarry.nildram.co.uk/SA80.htm SA80: Mistake or Maligned?] ==See also== Assault rifles British Army
Shouldn't a lot of that history be under assault rifle or similar? -User:Khendon 15:22 Nov 5, 2002 (UTC) Given the longer barrel, muzzle velocity really must be greater for the LSW. And I concur with Khendon on the assault rifle history part. - User:JidGom 23:14 20 Jul 2003 (UTC) The LSW muzzle velocity is indeed greater - unfortunately I can no longer remember the actual figures. I have a feeling the cyclic rate might vary too, though I'm not sure. I also wonder about some of the praise heaped upon the weapon here - although the SUSAT is indeed pretty good, I've not heard any particular reports of the SA80 being "widely regarded as the most powerful and accurate mass-production 5.56mm rifle." The claim that the Cadet GP's cocking handle extension makes it "the fastest action of any manual rifle" also seems pretty dubious for what is basically a bodge welded on the side to improve the ergonomics of a system never designed for manual operation.
