Another ATF Oops
From another of their yes it is, no it isn’t files, the ATF recently issued a position letter that stated Thompson machine guns were C&R eligible. Now, they’ve announced the letter will be rescinded. Seems they’re afraid that all machine guns will be classified as C&R items due to rarity.
You may recall a bit back where they said that engraving rifle converted to an SBR was OK then quickly changed their minds.
