I am fortunate all of mine took ~4 months. I am no fan of the ATF or FBI. However, if your letter to the FBI helps, perhaps you can share your letter for others to use as a template and remove personal information—just a thought for you to ponder. Have fun with your new suppressor.Wanted to give an update. Tom 264... I wanted you to know that they just approved my suppressor after I wrote the email to the FBI. I can't believe it. It's been 335 days... Maybe they'll prove yours shortly as well!
