There comes a time in a man's life when all you have is a rusty old shovel, some bullets and the need to combine them into a fully-functional AK-47. This man is Boris.
All you need is:
Shit shovel: $2
Romy sans-barrel AK kit: $200
Barrel blank: $30
Boris took his time and melted down the metal shovel head and reforged it into the actual gun receiver.
