I have wondered how long before BO did this. The importation of Russian 5.45x39 military ammo was stopped because of the armor piercing bullet and manufacture of AK pistols to shoot it. So I imagine they decided since we have all of these AR pistols now they would use the same premise to halt civilian access to M855. And all of this is done without congressional approval, so may not help to call Cory, but still worth a try.
