Trump is AT BEST apathetic about gun rights and is sure as fuck not going to throw the Chinese a bone. Literally nobody in power wants it, NRA takes a lot of funding from lazy American manufacturers that don't want competition and the antis wouldn't be happy with $300 AKs. Lifting that ban is a political lose-lose.
In a lot of places where they do have open importation of Chinese firearms it's like 70-80% of the market. It's almost impossible to compete with them. If you think are Glock clones errywhere gets annoying, literally one company errywhere gets pretty annoying too.
