I live in the good old U.S. or A. and pay the Pittman-Robertson tax on each gun and cartridge that I buy. I am aware of the tax. Apparently you are not.
Pittman-Robertson Federal Aid in Wildlife Restoration Act was established in 1937 for federal aid in wildlife Restoration Act. It in itself is a good tax used for a good purpose, but hidden from view to customers like you. It is charged directly to the manufacturers of firearms and ammunition and simply passed on through the retail distribution system to you. You pay many such hidden taxes, some of which are not well intended. Look at your phone bill sometime to see how many partially hidden taxes that you pay.
Are you aware of the additional tax and paperwork required to legally purchase/transfer a suppressor?
Because that is the paperwork and tax I was referring to.
Ammunition I can purchase without even producing an ID (one of the advantages of being at an age where no one asks for proof of age).
Not so a suppressor. Better documented than a 4473, and submitted in advance. There may be a BATFE master file on the 4473s, but there is definitely one on suppressor owners.
And yes, I have looked at my phone bill and seen the taxes and fees on that. But that is another string of swearwords...
