Wouldn’t be the first time it happened. IIRC Norinco got in some hot water a few decades ago for attempting to ship actual FA AK-47s into the port of Los Angeles.For some seriousness. I don't think this was shared on this forum. But CBP seized an arms shipment from China. This isn't the first one, but this is most recent one. Relevant because agitators are out in force.
