ANALYSIS: TRUE. ATF: 21st Century Suppressor Regulations are ‘Archaic.’ “In the past several years, opinions about silencers have changed across the United States. Their use to reduce noise at shooting ranges and applications within the sporting and hunting industry are now well recognized. At present, 42 states generally allow silencers to be used for sporting purposes. The wide acceptance of silencers and corresponding changes in state laws have created substantial demand across the country. This surge in demand has caused ATF to have a significant backlog on silencer applications.”
