M-91 Avenger / M-92 Mantis
The M-91 Avenger bolt action Marksman Microscale Mass Accelerator, colloquially called the M-91 Mantis Sniper rifle, is a powerful, long ranged weapon system produced by Hahne-Kedar Industries and served as the primary long ranged weapon system for the Systems Alliance infantry from 2158 to 2184. When it was replaced by the newer M-92 Mantis.
The primary components of the Avenger include a 1 meter long, 15 mm diameter coil gun barrel, a Micro Element Zero core, a small power cell, an ammunition block an air cooling system and an onboard computer microframe linked to targeting sensors and an integrated electronic scope.
The Mantic's components are largely identical to that of it's predecessor, with the only differences being improved software and a thermal clip based cooling system.
Appearance wise, both weapons are almost 1.5 meters long, with the barrel running the bulk of the length. On the top of the weapon is an electronic scope integrated directly into the weapon and linked to the sensors and targeting systems of the onboard computer of the rifle. The scope can see using both visual and thermal methods and it's concentration module uses motion tracking to see through smoke clouds.
In the main housing, behind the barrel is the Element Zero core and power cell. Beneath the barrel is the ventilation system. On the Mantis, the ventilation system is replaced with a thermal clip system.
The grip contains the ammo block made of a ferric titanium alloy, capable of proving 2000 rounds of ammunition. The sensors on the grip's exterior link it to the Combat Hardsuit of the wielder through the palm of their gauntlet. Displaying weapon and targeting information directly on the wielder's hud.
Casing of the rifle is made of a lightweight ceramic composite, with no metallic components aside from the barrels and ammo block, which contribute to the bulk of the weapon's 2.2 kg weight. The lightweight weapon counters recoil through momentum dampeners.
When firing, in the split second between the trigger being pulled and the bullet leaving the chamber, the onboard computer calculates the trajectory of the bullet based on wind, gravity, atmospheric pressure and other environmental hazards. It then makes micro-adjustments to the shooter's aim and shaves off an appropriately sized slug from the ammo block(about the size of a grain of sand). The projectile is then coated in an electromagnetic, bose-einstein condensate or plasma field to give it a so called "ammo power". These effects can be added through modification of the weapon on the field using an omnitool. This projectile is then moved to one of the barrels, lightened by a mass effect field, before being accelerated to 60 km/s. To prevent over penetration, the ammo block is designed with small imperfections. Ensuring that the round shatters on impact rather than passing directly through the target. The barrel has a recharge rate of 1.1 seconds between each shot. Trading fire rate for damage.
The heat generated by the gun is then transferred to the cooling system and removed.
In the M-19 Avenger's, the weapon vented the heat directly, but it often couldn't vent heat faster than it was generated. If the Kessler fires continuously for more than 2 rounds without stopping, the weapon could burn out. The M-92 Mantis solved this issue with the implementation of Thermal clips. Disposable lithium heat sinks that capture the heat generated. A bolt-action mechanism is used to expose the thermal clip compartment. Pulling back on the bolt automatically ejects the spent clip.
The immense power of the rifle, however results in the thermal clip reaching it's capacity after a single shot. Requiring a reload after every shot.
When holstered, the scope and stock retract, the grip flips up and the barrel folds up until the entire weapon is less than half it's original length.
