The new regulation is expected to cost gun owners over $260 million. It is expected to cost the federal government over $3 million. In addition to the cost, it will put an increasing burden on the already overwhelmed NFA division of the ATF. the ATF claims that the average wait time will be 90 days, although Silencer Shop is showing a wait time of eight months for a tax stamp. Not only will it bog down the new tax stamp applications for SBRs, but it might drastically increase the wait time for other NFA items, such as sound suppressors.
