The law (click title to entry - thank you) was written by the former Senator Larry Craig and signed into law by Georgie, but, that isn't why it is unconstitutional.
This seems fairly straight forward to me, actually.
It violates States Rights. In other words it allows the distribution of firearms by manufacturers to any state in the union in complete disregard of the State Legislation to prohibit them.
If California wants to make the sales of Assault Guns illegal this removes that by not holding responsible the manufacturers for the illegal distribution into the California.
Section 3 -
Prohibits a qualified civil liability action from being brought in any state or federal court against a manufacturer or seller of a firearm, ammunition, or a component of a firearm that has been shipped or transported in interstate or foreign commerce, or against a trade association of such manufacturers or sellers, for damages, punitive damages, injunctive or declaratory relief, abatement, restitution, fines, penalties, or other relief resulting from the criminal or unlawful misuse of a firearm....
It allows free interstate arms sales and transportation regardless of the laws of the State. Manufacturers have no responsibility to be sure their firearms are not found in California if they are prohibited there. That means they can sell freely to Nevada without any concern about the sales and transport to other states or over the border to Mexican Drug Cartels.
It allows manufacturers to sell to any gun shop, anywhere without worrying about whom their customers are. So, if a gun shop in Texas wants to sell weapons to mules going to Mexico the manufacturer has no liability in allowing such activity. As a matter of fact it encourages the sale of more guns 'for profit' REGARDLESS of the ultimate customer or use.
So, while American gun manufacturers should be held liable, as a deterrent, to the ultimate use of their product, instead they can sell them like water from a faucet. Imagine a group of rebels seeking guns for use against law enforcement in the USA. A very real scenario. There is no liability for the uncontrolled manufacture of guns going anywhere in the USA or abroad.
Better yet, Brazil. Brazil is one of the NRA's pride an joy. There are regular killings of innocent people in that country now because the Brazilian landscape is saturated with weapons.

S. 397 PLCAA was actually passed when the height of deaths of police officers were being realized in Brazil. The NRA was active in promoting the gun presence there and literally the Brazilian government could not stop it.
