Effective 26 December, 2025, The ATF-NFA will not be accepting Forms 1 & 4 for processing for Suppressors, SBR’s, SBS’s, and AOW’s. This is being done so that they can re-configure their system to allow for $0.00 for transfer fees. They will begin processing forms again on 01 January, 2026. Any forms that were submitted before 26 December will still be processed.
