Uboinik

"'H. .G Wells once wort, If we don't end war, war will end us.'"

Background
The Uboinik (Russian: Убойник, literally "murderer" or "killer"), also known as the Shambler in the English is an automatic revolving shotgun that was created from scrap by the metro dwellers at some point after World War III... or that they told me

Trivia
-It is a direct reference to the METRO 2033 franchise as it is one of the most iconic weapons in the game.

-For a piece of shit made from junk and metal from there, it's well done.
