Prototype Evrasium Precision Rifle
After careful testing (and more broken noses), we have found out that by bending the light using a lense, we could focus the kinetic output of the Evrasium crystals onto a precise target, particularly one of a bullet nature.
The PEPR is the first attempt at weaponizing Evrasium. On the outside, it is a bulky, bullpup style rifle, with an incredibly short barrel. Inside, it is an intricate, yet mechanically simple, device that holds a much smaller version of the Evrasium crystal we use in our reactors. Upon pulling the trigger, an array of lasers around the center of the gun fire at a lense, and the electromagnetic radiation is focused to a precise point on the crystal, triggering a kinetic reaction that fires the bullet in the chamber. As there is no need for gunpowder, we fire the whole bullet, that's 65% more bullet per bullet there is no need for casings or concerns of jams. There is also no concern for buildup, like those ancient guns, making the PEPR much more reliable. Additionally, the precise nature of the crystal's 'kick' is much better at forcing the bullet to travel exactly where we want it, meaning the length of the barrel (a source of high heat generation) is only long enough to hold the round in place before firing.
A secondary laser fires at the exact right time, causing the crystal to fire at a turbine in the stock causing three seperate actions. First, the turbine reduces the kick from the gun, improving stability. Second, the turbine generate enough power to recharge the batteries powering the lasers. Finally, it rechambers the next round, allowing it to function in automatic and semi-automatic, even in 0g.
The PEPR of course does not come without drawbacks. The Evrasium crystals have to be cut down to a precise shape in our factories, and don't last forever. Thankfully, a hatch has been built into the side of the gun that allows the crystal to easily be extracted and replaced with a fresh one that fits perfectly into place. The operator needs to take care to not overexert the crystal's durability, as increased damage to the Evrasium matrix reduces accuracy and leads to a messy cleanup inside the system.
