If enactted (I doubt nothing with this current crop of non legislative legislators), that would serve to drive up the prices of components and Interestingly, I just read on a vendoir's website that Winchester was enacting a 17% across the board price increase.
Isn't Winchester a wholly owned subsidary of Olin?
So, you increase pricing to where it becomes too expensive to load your firearm. I suspect all other manufacturers will follow suit.
Profits for all and piss on the consumer.
Of course IMO, Winchester is junk in the first place.
