Numo
From Battlestar Wiki, the free, open content Battlestar Galactica encyclopedia and episode guide
A numo is a weapon similar to an air gun, which works on compressed air. This weapon is apparently native to Equellus, as Apollo claims to have never seen one.
Puppis claims that a numo can kill a lupus from 10 metrons. Before that claim however, Puppis claimed that his mother, Vella, was unable to hit the side of a granary with a numo (The Lost Warrior).
