This rare handgun was made to function in an unusual environment. Can you guess what that is? Hit the jump for the answer.


Underwater. According to my sources, the Soviet 4.5mm B-VI-307 was developed in the 1960s specifically for submerged use. The gun never made it into production. The one pictured above is at the Central Armed Forces Museum of Moscow.

Did you guess correctly?
