root@dahl-db:~$ cat description.txt

Dahl's take on a rotary assault rifle, built around a three-barrel assembly and an instant full-speed spin with no wind-up. Hip-fired, it blooms badly under sustained fire, but aiming turns it into a brutally fast nine-shot burst that stays surprisingly accurate even at range. It excels at pouring precise bullet volume downrange, though it chews through magazines and ammo very quickly.

It uses a Vladof-style rotary barrel, so it only appears at green rarity or higher. Random world drop from suitable loot sources.
