Discharge Information

Projection/ammo type: Multiple Caliber Chemical Propelled Solid Munitions

Firing Mechanism: A round is fed into the chamber from an external magazine when the bolt of the firing assembly is pulled back. The pulling of the bolt prepares the trigger assembly's mechanism. When the trigger is pulled, the mechanism releases, and forces the hammer which is connected to it and enclosed in the firing mechanism assembly to collide with the propellant/casing of the munition. The hammer's impact, combined with a piezoelectric spark ignites the munition's propellant. The gas released from the propellant propels the projectile down the weapon's barrel. The gas released from the propellant is also utilized to re-initiate the mechanical procedure which fired the initial shot, enabling the weapon to continue firing after the initial discharge.

Caliber: The weapon can be adjusted to accept munitions ranging from 4mm to 12mm, with casings ranging from 4mm to 13mm in width, case lengths from 10mm to 60mm, and overall lengths up to 80mm.

Self-Adjusting Bolt: Through the use of a picoscopic-machine laden metallic jelly (The technology for which seems to be borrowed), the bolt of the rifle is capable of expanding or contracting to allow for the proper chambering of cased and caseless munitions, and to properly accommodate a large number of various munitions. The expansion and contraction is handled automatically by the jelly in automatic adaptation to the ammunition chambered.

However, ammunition of approximately 7mm does not require pico-jelly to seal the bolt properly, due to the inherent physical design of the bolt.

Standard Issue Replacement Pico-Jelly: Issued with each rifle is a 3oz container of pico-jelly which is to be applied to the bolt of the weapon during maintenance procedures. It is advised that this be done after every 400 discharges.

DO NOT ABUSE YOUR PICO-JELLY SUPPLY, your issued amount of pico-jelly is not to be utilized for uses other than rifle maintenance.

Visual Description


The mutli-caliber rifle has been designed by the Lorath Matriarchy and Lorath Self Defense Force to be fielded by infantry and some power-armor forces. Due to the nature of the Lorath, the rifle was accepted with remorse and regret, thus the rifle was dubbed with the title “Soh'mit Dy'c” or “Cursed Tool”. Despite the regrettable need to utilize such a weapon, soldiers who are issued the rifle treat the weapon with the same respect they treat their melee weapons which they still wear even as they field their rifles.
