The Blue Language makes it. The Russians just needed a gun they could cheaply make to arm their massive army. “Adequate” is a good way to describe cold-war weapons. Does the gun shoot? Yep. Will a Cabbage Farmer from the banks of the Volga be able to hit another man from across a battle field more-times-than-not? Yep. Is the cartridge effective enough that a hit soldier will be reasonably compromised? Da comrade! Will it hold up to abuse and neglect? Yep.
And if all of this doesn’t work does it have a big spike on the end of it that can be used as a spear? Da, and not only that the heavy stock can be used as a swell club!
That works! Start production, we need a Million by the end of the month!
And even when the NEXT Adequate rifle came out they held onto the old ones for decades JUST in case they had more soldiers than they had rifles, because what killed men 30 years ago will still kill them today!
And now they ship them here, and they’re fun to collect!
