Caverns Armory – Form 4 Update
Recent court rulings regarding SBR, SBS, suppressor and AOW transfers have not eliminated the Form 4 requirement for all dealers.
At this time, Caverns Armory is still required to complete the standard ATF transfer process, including submission and approval of a Form 4, before transferring a suppressor to a customer.
We are monitoring the situation closely and will adjust our transfer procedures if future court rulings or ATF guidance changes the requirements that apply to Caverns Armory.
For now, customers purchasing SBR, SBS, suppressors and AOW through Caverns Armory should expect the normal Form 4 process to remain in place.
