History
Following the development of new assault rifles by other nations using intermediary cartridges, the decision was made to produce a new Praetonian rifle with a new Imperial Ordnance round to use with it. The rifle is of the bullpup configuration, like all previous Praetonian assault rifles, and is designed to be able to operate at a longer range than assualt rifles such as the M16 and G36.
Ammunition
As well as a new rifle, a new round was needed to go with it. The new round had to be both light and small but also able to impart a large amount of energy to its target, and so a heavy caseless 6.3mm tungsten round, weighing 8.2 grammes, was developed with a suitably large 35mm charge behind it. The ammunition is believed to have an effective range of 750m when fired from the L63, assuming the operator is able to aim accurately at that distance.
The 6.3 x 35mm Imperial Ordnance round, as it is now known, is capable of penetrating most body armour carried by troops, especially at short range, and with practical certainty with burst fire. The round is also sufficiently powerful to penetrate several sheets of regular glass and thin steel whilst retaining the ability to inflict a lethal wound at the end of it.
A version of the 6.3mm round made of 'blended metal' is also in production, but this bullet has been limitted so far to special operations sections due to concerns about its penetrative capailities in a general combat scenario.
Weapon Layout
The L63 is arranged in a bullpup format, with the 40-round magazine or 80-round drum located to the rear of the weapon, with the pistol grip just behind the forward hand grip. The weapon is 800mm long, of which 550mm is barrel. The long barrel imparts considerable speed and accuracy to the bullet, whilst the bullpup format keeps the gun suitably compact.
The weapon is constructed primarily of aluminium alloys and light composite materials, and weighs 4.25kg fully loaded with a scope attached to one of its two detachable rails. The primary such rail is mounted above the gun, and is usually used for mounting a scope, and the secondary rail is mounted below the grip and is used for mounting a 40mm grenade launcher, torch, Etc. A 12" sword or 5" knife bayonet may be attached to the muzzle guard.
The L63 can fire single shot, burst or full automatic. The ammunition is fired electronically in order to allow the 3-round burst a RoF of 2,200 rounds / minute (or the whole burst fired in 0.08 seconds). The full automatic mode is limitted to 650 rounds / minute in order to avoid wasted ammunition, although it could theoretically go higher. Both rails carry a wire from the gun into suitably equipped accessories, allowing an underslung grenade launcher to be fired electronically from the same trigger as the KE weapon, and to feed information from the forward mounted laser rangefinder to the scope.
In order to save power, the gun has a recoil energy-reclamation outer barrel which recharges the battery (with a shelf life of 15 years) as the weapon is fired. Since the recoil of the rifle greatly exceeds the small current required to ignite the primer in a round, in theory the battery can last indefiantely without recharge. However, if energy-consuming accessories such as torches, the laser rangefinder and scope, Etc. are left on for long peroids it may be necessay to recharge the battery manually. In an emergency, rounds may be expended in order to recharge the battery, and a manual charging system exists in case the battery completely runs out of power and is incapable of firing another round.
Integrated General Scope (IGS)
Based on the British SUSAT, the L63 is equipped with a scope as standard - usually 4x magnification, although both 2x and 6x are available. The IGS, like the SUSAT, is carries a tritium illuminator for night fighting. Unlike the SUSAT, the IGS has an electronic overlay (which is not required for the operation of the scope) linked in to the weapon's laser rangefinder which displays the range of whatever the weapon is pointed at, giving the user vital information for adjusting his aim, as well as allowing him to report exact positions of enemy troops and vehicles.
The scope is highly durable and constructed mainly of aluminium. Lense caps are provided to protect the lenses, and the electronic overlay view (as well as the rangefinder) can be turned off most of the time in order to conserve electricity. Ironsights are also available for the rifle, but are not generally used in Praetonian service.
