The policy follows an Oct 9 ATF open letter that ended federal registration, approval, and tax stamp requirements for these items nationwide. The shift occurred after Congress eliminated the $200 tax on suppressors and short-barreled rifles, leading a federal judge to rule that Form 1 and Form 4 registrations were no longer required. While machine guns and destructive devices remain under National Firearms Act regulation, buyers must still pass NICS checks and complete Form 4473.
