"A motley cacophony of short wire loops surrounds a long metal rail. An ungainly stock and magazine are mounted to the side."
This weapon holds only one lead slug, but also needs an energy cell to operate.
Its penetration value matches AV of the target, like attacks with Vibro Blade. This makes it invaluable against heavily armored targets such as Leering Stalker, Decarbonizer or Great Saltback, but inferior to Scoped Masterwork Carbine against vast majority of creatures in the game.
It's currently not craftable, being only rarely found in ruins.
