Plasma Rifle with conversion

Next generation weaponry is so much fun ^_^

Here we have an advanced plasma rifle, powered by thermo-batteries, good for 100 shots before needing to recharge at an ammo station.
Underneath, a conventional munitions conversion, firing fin stabalised discarding sabot AP rounds from a 25 round magazine.
Fire selector is simple on the Plasma Rifle, either Safe or Kill
Conventional has option of Safe, Semi or Full Auto fire modes.
