Here is a GREAT article explaining why you should comment and oppose the NFA rules changes proposed, as well as all the information you need to make cogent and persuasive arguments to shut 'er down! Please give it a read (you dont have to read all the attachments, there are 90+ pages, but its easy to navigate for info and provides great guidance. I high recommend you read the front, and delve in if needed, then make a comment on the proposed rule changes before Dec 9, 2013! The fight must continue on all fronts!
