Classic Arms — all Saigas are sold out...
Wolf, Brown Bear, etc — this type of ammo is gonna fly off shelves and become scarce soon.
First it was the 5.45x39 rifle ammo specifically, now they're going after the rest. Nobody should be surprised by this, after the "under the radar" comment and the inability to get any gun-control measures past the House.
Controlling firearm and ammo imports is as easy as a call from Valerie Jarrett to the BATFE administrator - that agency already has control of such import approvals. An Executive Order isn't required, except as an in-your-face gesture.
I'll bet the .223 AK finally gains popularity.
