Without reading the actual legislation, I would assume it exempts state and local police from the bans and scary, looking rifles. It would be a shame, if gunmakers simply refused to sell, said rifles, or parts to repair them, to any law-enforcement agency in the state.
I wish it were that easy to block sales to certain states, but a lot of law enforcement purchasing is done via multi-state or national “public safety supply” companies, which sell everything from handcuff keys to firearms. I’ve seen “storefront” locations of those distributors where you had to flash a badge at the cctv camera to even get in the front door. IOW, not overly friendly toward the non-LEO public.
