The Col-16 Gun was inspired by Greg Foertsch from Firaxis. 
On the Firaxis Panel in PAX South 2016 Greg Foertsch asked for a gun that shoots pigeons , he noted that the weapon could exist since the pigeons are particle effects, Now we have that weapon. 
The weapon also has +3 damage and has a -10% chance of a critical hit. (as we all know pigeons hit hard but you cant aim them) 

The model will be changed soon.
