ET-7 Electrothermal Rifle

This specialized weapon fired a cased round but does not use a gunpowder propellant; instead, it uses a huge 10,000-volt electrical charge to ignite a liquid fuel into a plasma-state. The resulting continous propellant boost has an almost hydraulic push over time, reducing recoil to about the same as that of a normal rifle. Muzzle velocity is 1,800 m/sec, giving the ET7 a 50% boost on range and damage over regular rifles.

The ET7 are not actually a rifle at all, strictly speaking: It have a smooth bore and fire fin-stabilized rounds. A 20-cm-long, 3-cm-wide cylindrical battery provides enough energy for about 100 shots.
