The Bureau of Alcohol, Tobacco, Firearms and Explosives released an Open Letter and Frequently Asked Questions explaining how it will treat ownership, transfer, and transportation of the National Firearms Act (NFA) firearms for which Congress eliminated the making and transfer taxes in the One Big Beautiful Bill.



Under ATF’s guidance, ATF will not enforce the requirements for individuals to apply and receive ATF approval before making or transferring short-barreled rifles, short-barreled shotguns, suppressors (silencers), and certain other concealable firearms known in the law as “any other weapons.” ATF also will not enforce the NFA’s registration, tax-stamp or related requirements for those covered items. The $200 tax remains in place for machine guns and destructive devices. The NFA requirements apply in full to those weapons. The guidance does not supersede state and local laws that restrict NFA firearms.

Now I can use my TC super 14 barrels on  shoulder stock.

And I can use my XP-100 with a 15" barrel 7mm TCU and a shoulder stock I made for it, 30 years ago. 

I shot it a few times back then but, got paranoid and it hasn't got out of the case since then.

I'll check into it.
