I know a guy (IKAG) who purchased several firearms since this nonsense began. Each came with a fired casing in a small coin envelope with identifying information. The extra cost of supplying this was no doubt included in the purchase price of the firearm.
The cost of this nonsense to those manufacturers, passed on to consumers, was no doubt several more millions. There is no price so high that anti-gunners are not willing to have gun owners pay for their fantasies.
These manufacturers should sue the state of Maryland for the costs of having had their Second Amendment right to manufacture arms infringed.

Just like any 'taxes' that a business has to pay...
