Americans are stocking up fpr the fight against their government.
DHS ordered 2,700 APC's and 1 billion rounds of ammo. This is causing massive blowback among many Americans. IMO, what this will lead to is Russian and Iranian illegal gun running into the USA. Now that a box of 20 306 shells is $28, there is a huge profit opportunity.
I have no actual info, but my guess is, having put up with 30 years of US gun running in their countries, our enemies are chomping at the bit.
