In Part 1 of this article, I wrote about the beginning of the Kalashnikov machine gun story.In this chapter, I will get into details of how Kalashnikov managed to go through with his design against all odds.After a month of hard work, the first prototype of PK was ready.By that time, the rival machine gun designed by Nikitin and Sokolov completed technical trials and had a few non-critical issues that design engineers had to fix.Kalashnikov’s machinegun wasn’t even officially tested by the factory, so he didn’t really have any chance to win in this trial, since the competitor, Nikitin GPMG, was so ahead of him.
