This toroid is then ejected down a superconducting barrel against a given target. When depressing the trigger, a plasma toroid is produced that can remain stable under normal atmospheric conditions. This rifle uses a microfusion cell as its power source and draws plasma from a separate cartridge. Prior to the nuclear Armageddon, REPCONN Aerospace (as a subsidiary of RobCo Industries) would successfully develop an improvement from their spaceflight research, with significantly advanced factions tinkering with the design post Armageddon. This however was not the end of the design nor manufacture of this weapon platform. This design was produced and fielded in number prior to the Great War of October 23, 2077. This plasma rifle is a lightweight urban warfare weapon created as part of a desire to replace the aging Winchester P94 'Plasma Caster' design.

Initially, the weapon was a bulky, industrial plasma caster, manufactured by Winchester Arms while it performed admirably, it was expensive and required specialized training to use.

In extreme cases, the plasma can cause spontaneous dissolution of the target, including separation of soft tissues from hard ones or wholesale molecular destabilization that turns the target into a viscous green fluid. The primary damage mechanism of plasma rifles is thermal transfer, causing serious burns to soft targets and melting hard ones. However, the plasma bolt chamber can be hotwired in order to accelerate the bolt formation process, effectively turbocharging the rifle. The bolts form into toroids in the plasma chamber, which are then sent down a superconducting barrel. Plasma rifles or plasma casters are high tech weapons firing superheated bolts of plasma, powered by either microfusion cells, heavy energy cells, plasma cartridges, or plasma cores which find numerous applications in military and industrial fields.
