"You don't need to be a PAL holder to purchase this uncontrolled item, but we require it just in case the government may in the future" is the same as "you don't need to be vaccinated in order to eat here, but we're requiring it in case the government may in the future."
If you think that inadvertently selling an uncontrolled item to a gang member or a potential "mass shooter" will drive further nails into the coffin, you're wrong. Those who hate civilian gun owners will continue to hate civilian gun owners and the ruling elite will take advantage of their inability to process information. If there is anyone capable of critical thought then they will come to a logical conclusion with or without help. But to make the statement that "we're all going to be good boys on our best behaviour so the government will leave us alone" is incredibly disingenuous to those who are gullible enough to fall for that asinine belief. You cannot talk your way out of getting murdered just the same as you cannot behave your way into being treated fairly by the government.
No amount of checking PALs to prevent 3D printing will keep your community safe. Gun owners will be in the crosshairs until they are all disarmed, though after seeing how much praise some of you give law enforcement it seems that your cognitive dissonance welcomes you being disarmed. Do you really believe Trudeau and Blair, themselves, will be knocking on your door come confiscation?
BBC did some great cerakote work for me recently, but I will not give my support or money to a company that takes measures, however good intentioned they may be, to further restrict ownership of items that I believe should be completely unregulated.
