The gods of design werent very happy about my absence in the field...
Ah screw it, Im not the religious type either.
Luna Industries K-15 Battle Rifle.
In the final years of the 23rd century, United Earth military officials have declared sniper-type long range rifles obsolete, instead preferring smaller, compact Assault Rifles, more suitable for close to medium range combat. During the Sol War, it was shown that snipers were still of great use in the battlefield, as shown when a Federation sniper team managed to infiltrate and slaughter half a platoon of United Earth soldiers before disappearing into the night. Convinced that snipers were still effective an effective fighting force, the United Earth military restarted it's sniper program as well as ordered the development of a new, long range rifle for the new snipers.
The K-15 was the result of this rather quick move by the military. Based on old plans Luna Industries had made for a battle rifle nearly 30 years back, the K-15 benefited from new advancements in firearms technology as well as composite materials. Made of lightweight and strong materials, a ready and fit soldier can use a K-15 as easily as he uses his standard issue rifle. One of the great advancements of the K-15 is it's intergrated LONGSHOT computer system. The LONGSHOT allows precise calculations using the onboard microcomputer and sensors in the K-15 to calibrate the rifle's sights based on windspeed, target distance and even the gravitational pull of the planet and it's moons. This allows the K-15 to be one of the most accurate infantry weapons in the United Earth arsenal. In addition, the Fenlas F-2000D scope also comes with manual controls, allowing the sniper to adapt in conditions in the event of computer failure or environmental factors.
The electromagnetic systems of the K-15 allows the rifle to hurl a .50 calibre round to up to 5 miles with deadly accuracy. Soldiers using the rifle can manipulate the charge of the electromagnetic coils to compensate between rate of fire and penetrating power. The standard firing charts are below.
100% charge: Maximum Penetration to up to 5 miles (7 in theory). Recharge time of 1.2 seconds.
50% charge: Maximum Penetration of up to 1 mile. Recharge time of 0.8 seconds.
25% charge: Medium to short range combat. Fully automatic. Penetrating power equal to rounds fired from a standard assault rifle.
The K-15's standard magazine allows holding of up to 28 .50 cal rounds. In addition, due to requests by many Allied soldiers, the K-15 is also able to fire standard gunpowder rounds in addition to it's coilgun function when necessary.
The K-15 now equips United Earth Infantrymen as a Battle Rifle as well as a dedicated sniper weapon (with Fenlas scope)
Admittedly, I suck at gun design. Even the history Im not sure what Im writing. Any criticism is much appreciated.
