The Rifle, Model 5, Enfield Mk-2, much like its 1000 year old ancestors, the Magazine Lee-Enfields, is ubiquitous throughout the United Commonwealth, and at nearly 200 years old, (accepted into service in 2790), the EM-5 makes even that venerable weapon family look short lived.

The main laser resonance and coherence chamber is powered by a set of supercapacitors in the lithium-ion battery that is inserted like a ballistic magazine. The chamber is filled with a gas, either KrCl or ArF depending on the expected power output. These have different wavelengths, both in the UV part of the spectrum, 193nm (ArF), 222nm (KrCl). Also present, a secondary laser module in the blue part of the spectrum. This secondary module is a laser diode and allows for accurate aiming, like a tracer on a ballistic projectile. This can be turned off on the EM-5D for extra stealthing.
History
In 2751, the Commonwealth, using the EM-5s predecessor, Rifle, Model 18, Kolkata, ran into a new sentient species, that was given the name the Furies, in a series of short conflicts that did not end at all well for the Commonwealth called the First War of Retaliation. This was because, for the first time since entering the cosmos, the Commonwealth was outmatched technologically. In part, this was due to the KM-X series of rifles having a maximum output of only 150 kilovolts.
Although this output was more than plenty enough when dealing with other humans, it was not enough to damage the Furies. Having grown up on a world that was too close to its sun, Furies are naturally much more heat resistant than a human and so for directed-energy weapons to be effective they have to transfer at least 1×108 volts into the target to even begin to burn them, let alone pierce them. The Furies, therefore, had the drive to successfully invent both the capacitor technology that could hold a minimum of 1 gigavolt and small enough laser stimulation chambers that could use that power that could fit within a rifle as well glass technology that could resist melting for fibre optic barrels. Their rifles were rated at 2-3 gigavolts, more than enough to fry a human and even put a huge dent in most of their armoured vehicles. Despite its best efforts, the MoD could not capture an intact example of the Furies standard rifle to try and reverse engineer, because of a mixture of constant retreat and the self-destruct mechanism built into the rifles. The war finally turned when, in 2756 an MI6 officer, a Mister Jeremy Braxton, successfully returned 4 complete weapons for study at RSAF Enfield.
By 2770, a working prototype of the Rifle, Experimental Model 5, Enfield had been built and in 2772, 200,000 of the 10 gigavolt XM-5 were built and issued to the frontline troops for extended field trials. It was an instant success with the mechanised infantry units, allowing them to kill a fury at distance. However, in the light infantry regiments, it was less well-received; because although the 10 gigavolt power guaranteed a kill at ranges below 500 metres the beam quickly lost coherency and prevented any usability above 1200 metres, due to the extremely small coherency chamber and short barrel (See EM-9) of 400 millimetres.
In light of the feedback, that also included 10 gigavolts being too powerful for a standard rifle as battery packs lasted only 150, 10 millisecond, beams, 1/20th of the old KM-X series, the rifle was stepped back to 6 gigavolts which, using the standard battery, gave 500 shots. The ability to vary the power between 25% under and 25% overvoltage was added at request so to elongate the battery time even further, especially if used against human targets. The Barrel was extended by 100mm to extend the range out.
In 2775, the rifle was officially formalised into its standard form the Rifle, Mark 5, Enfield or EM-5, Mk-1. In 2790, the EM-5 was given an update to the Mk-2 standard (along with the EM-9). This improved the optics and improved battery life; increasing the coherency range to 1500 metres(with an absolute maximum of 6,000 metres) and upping the capacity to 1000, 10 millisecond, beams per battery and improved service life of 10,000 cycles. The Mk-2 was also officially given the upgraded adjustable buttstock and cheek pad system that was taken from the KM-18, this being technically added to the EM-5 mark 1* in 2776, after field armourers had been retrofitting the KM-18s stock to the EM-5 for the women of their units. The full-length rifle also came with a different forend for attaching a Underbarrel Grenade Launcher, via lugs rather than the K-block system.
At the same time, a new carbine and a newly designated marksrifle based on the Mk-2 frame, the EM-5C and D, were produced. The EM-5C 'Commander' carbine went back to a short barrel, about 380 millimetres long, and was designed as a PDW for platoon sergeants and officers (as well as Artillery crews and the like), with an Laser Designation Module, Mark 45 unit as standard for aerial designation, LIDAR and general aiming. This Carbine has the improved optics and layout of the Mark 2 EM-5, but with the stepped-down voltage of the EM-9, allowing for a 300-metre effective range, more than enough for self-defence.
The EM-5D 'DMR', was designed to replace the ballistic sniper Rifle, L-1733, as the section DMR. In order to do this, the weapon was modified so that the voltage and rate of fire selector switches were omitted, and the power output return to 10 gigavolts In addition the barrel was increased in length to 585mm and made thicker, and the rifle given a bipod and LDM, Mk-45 as standard, as well as 4-20 power scope. To reduce the report even further from the long rifle, the passive vacuum muzzle device was replaced by an active Argon suppression system, with gas ejected, as the trigger is taken up, from bottles in the fixed stock.
As with all laser-based weaponry, sights, lights, designation and aiming lasers etc are powered through the main battery, through resistors, bleeding off very little power, and generating a shot counter found in the sights reticles. Although these weapons can take iron sights it is extremely frowned upon.
Even after 100 years the mk2 is still holding its own; even against the terror that is the Tarquin.

Raw materials & Components
Plastic lower receiver, Aluminium Upper, Glass Fibre Barrel
The barrel is a fibre optic cable surrounded by a carbon-tungsten-titanium composite that protects the glass from oxygen and is heat resistant. The muzzle device for standard EM-5s is a vacuum, but in the EM-5D has an argon purge system to ease the transfer of the laser pulse to the atmosphere and reduces the Ozone creation report, which at 10 gigavolts is considerable.
