When I purchased my first suppressor six years ago, it took the BATF about9-10 months to approve the purchase and the possession of the suppressor. Over the years, the approval wait time has improved, three years ago, the wait time was 5-6 weeks.
Last Friday I purchased another suppressor, and the purchase was approved the following Monday. Speaking with some gun shop employees, one of their customers had their approval in 19 hours.
I always wondered why it took so long, in this age of computer technology. Looks like at least one federal agency is getting their act together.
I look forward to the day when suppressors can be purchased like any other shooting accessory, and no government intervention is involved. Hopefully, that day will arrive soon.
