Well, the gun most used by third world militia is the AK-47 due to how cheap it is, probably the cheapest machine gun. However, certain chotguns are also really cheap. But my guess is the AK-47. If not, a shottie.
a toy gun :D

1-10 USD
One of the Cheapest is the Marksman 1010 Repeater. It cost under $30 and is not accurate nor powerful.
the cheapest gun on aqworlds is either the crossbow or the shotgun. i believe they both cost around 12,500 gold but that is pretty cheap compared to the colt revolver that is worth 300,000
Marksman 1010 is the cheapest and slowest BB gun on the market.
The brass eagle talon is 25 dollars.
