Cadet GP Rifle (GP - General Purpose) is the advanced rifle used by the Army, Navy and Air Cadet shooting. This weapon was introduced alongside the SA80 from 1989 onwards for cadet use, as at the time cadets were only allowed to fire semi-automatic weapons.

The GP rifle strips for cleaning without the gas parts it almost identical to the L85A1 (SA-80). It consists of: barrel and receiver, trigger mechanism housing (TMH), cocking handle and extension, bolt carrier containing the bolt, firing pin and cam stud, and the recoil rod assembly, all of which can be removed and reassembled relatively easy without tools. The sight and foregrip can also be detached with the aid of the combination tool; because there are no gas parts venting carbon fouling into the handguard this item need not be removed as frequently as on the other SA80 weapon.

rifle and cannot fire fully-automatically. The SA80 IW and LSW are cocked via a cocking handle attached directly to the bolt carrier. The GP rifle, however, has a cocking handle extension piece, and is cocked with the right hand as opposed to reaching across and cocking with the left (Air Cadets are trained to cock the L98A2 with their left hand). The drills for the other SA80 weapons mandate a "forward assist", a tap of the cocking handle to ensure the bolt is properly closed. This procedure is not required on the GP, the extra weight of the cocking handle assembly giving the bolt carrier sufficient inertia to close reliably under its own power, although as dirt gets trapped in the locking lugs frequently a forward assist is required to ensure a proper lock, especially after many rounds have been put through the weapon.


Before using the weapon with either blank or ball ammunition, cadets receive training in the safe use of the weapon. Drills that are taught include:

  • Normal Safety Precautions (NSP's) (ensuring that the weapon is an unloaded state prior to use).
  • Stripping (and reassembling) the weapon for daily cleaning.
  • Filling magazines
  • Loading the weapon
  • Make Ready (cocking the weapon to move a round into the chamber)
  • Make Safe (reversing the result of a "make ready", after which there will no longer be a round in the chamber.)
  • Immediate Action (IA) Drill (Drill to be performed if the weapon should stop firing unexpectedly)
  • Stoppage Drills (Drills that are performed rectify what has caused the weapon to stop firing)
  • Unload (removing the magazine from the rifle and ensuring there is no round in the chamber)

Cadets are also asked to learn the five characteristics of the rifle. These are:

  • The L98A1 Cadet GP Rifle is a magazine-fed, semi-auto weapon firing based on the British Armed forces L85A1 Rifle.
  • It can only be fired from the right shoulder if fired from the left shoulder it can cause damage to the jaw or nose
  • It has a magazine capacity of 30 5.56mm rounds
  • It is robust, yet light and accurate but when using the DP it has a concert barrel making it significantly more heavy
  • Its low recoil and high adaptability but when firing single shot from a range it is easy to lose track of target unless butt of the weapon is tucked in tight to your shoulder for firers of differing physiques makes it a practical rifle for cadets.

A standardised Weapon Handling Test (WHT)/skill at arms test covering the above points must be passed before a cadet may shoot.

On exercise cadets will use the GP rifle to fire blanks in fieldcraft scenarios. Because the L98 does not have a flash suppressor a Blank Firing Attachment (BFA) must be fitted to the Weapon.


The L98A2 is fitted with adjustable iron sights. It consists of a rear emergency battle and leaf sight and a front blade sight. The front sight is mounted on a protrusion extending from the barrel upwards through the handguard which would be the gas block on the SA80 IW or LSW. The front sight assembly is clamped to the top of this and carries the front sight blade with protective fins either side. Zeroing in elevation is carried out by turning a wheel that raises and lowers the blade. The rear sight is fitted at the rear of the carrying handle, with zeroing in windage performed using a wheel on the side. This, like the elevation wheel on the front sight, is locked in place by a spring-loaded pin, and is best adjusted using the combination tool. The rear sight has a frequently-used battle sight, zeroed to 100m, which flips over to reveal an adjustable leaf sight. By turning a range dial differently-placed apertures are moved into position behind a slot. Ranges from 100 to 500 metres are available, though because the zeroing settings are shared between all of them they can only be correct at one chosen range (usually 300m). The battle sight is nominally zeroed for use at 300m; since zeroing is important only when firing live ammunition, which cadets do only on a range with plenty of time to flip up the main sight, this is largely irrelevant.

If available, the SUSAT can be fitted to the GP but never normally is, though larger units such as the CWS night-sight and the original SAWES laser-training projector would foul the GP's larger cocking handle and cannot be used. In day-to-day live firing exercises only the iron sights are used.


The L98 has a number of features which can cause problems, particularly for cadets of a smaller physical stature.


It can be difficult to secure the weapon's magazine - this can lead to a change in the loading drill requiring cadets to place their left hand above the magazine housing and lean on it to ensure it was secure. This is generally only a problem with a full magazine, loads of 10 to 20 rounds are generally not affected by this.

Cocking handle[]

Failing to pull the cocking handle fully rearwards (again, a particular problem for smaller cadets, with shorter arms) often results in the ejected case being caught between the breech and the working parts as they come forward, resulting in a stoppage. Also the large external slide is prone to collecting grit and dirt making it harder to cock and increasing the chance of a stoppage. Furthermore the cocking handle can be prone to come away from the weapon completely at times. Also to add to this many cadets tend to force feed the cocking handle and cause the rifle to encounter a stoppage.


In 2009 - 2010, the weapon was coneen talk of rifles for cadet use being sidelined in favour of clay pigeon shooting, though many argue this is restricting cadets from improving on marksmanship principles.


Conversion kits exist which, when fitted to the weapon, enable it to fire .22 rimfire cartridges instead of the standard NATO cartridge. This allows the weapon to be fired live on .22 ranges, as might be used for No.8 rifles, when full size military ranges are not available. The kit consists of a modified bolt carrier assembly, a special magazine that is the same size and shape as the standard 5.56mm magazine, is actually mostly a solid mass of plastic with a much smaller .22 magazine held inside it, and a special adapter, shaped like a 5.56mm cartridge, which is fitted into the L98A1's breech and itself contains a smaller breech into which the modified bolt inserts the .22 cartridge. The modified magazine locks into the magazine housing exactly as a normal one would, the normal extended cocking handle is connected to the modified bolt carrier, and the method of operation is exactly the same as when using 5.56mm ammunition. The conversion is not permanent and the kit can be fitted or removed from the weapon in as little time as it takes to normally strip and reassemble it. The conversion also has the effect of making the weapon semi-automatic, with

the cocking handle only needed to be pulled back once.

Weapons handling test:

1) Check safety catch, all the time.

2) Always Forward Assist, this is when you tap the cocking handle to make sure it it fully forward before firing.
