Last week, the players discovered that the world’s smallest gun Kolibri has been featured in Battlefield 1. Developer of the game, EA DICE have been historically accurate about the fact that Kolibri was used in during World War 1.
Although Kolibri is a fun gun to use, it is the least damaging weapon in the whole game. It deals only 4 damage points per bullet and 25 damage points per head shot.
If you are interested in using this tiny gun, it is not very tough to unlock as you just need to work a bit and can easily unlock it without paying any actual money.
