The Afghan villager does not want to rely on future Russian/Yeerk invasions, and therefore creates his own kalashnikov/dracon beam by dissassembling the original, figuring out how it was made and then making more for himself and others to use in conflicts.
Buy a man a fish or teach him to go fishing? Who wants to be relient on the chance of finding a create full of kalashnikovs/dracon beams when you could learn to make your own (which you would then be able to modify to your own requirements as well).
Implicit in this idea is having access to the original weapon, studying it, dissassembling it and making more yourself. or to rephrase in more obvious terms
1. find or capture one original kalashnikov/dracon beam
2. take back to workshop, study, practise with, dissassemble.
3. re assemble etc until you understand how it works.
4. make your own
5. make even more
6. modify to suit your own circumstances.
7. produce even more of the modified version.
8. widespread de-centralised distribution of dracon beams leads to even more deaths/choas in Africa,Middle East etc.
Notably the yeerks themselves basically did this with the Andalite shredder and ongachic weaponry thus creating the dracon beam.
