All I can say is.... the ATF is the ATF and they can pretty much do as they please, legal or not. I wrote them a very simple request for information LAST JULY, regarding how they determine what is a brake and what's a flash hider, also, what methods of attachment for brakes on post-ban rifles would they buy. I know how some shops are doing it, threaded on-blind pinned-welded over the pin.... I was asking about methods that would not require any barrel threading, and, how about machined directly into the barrel. I have contacted them numerous times since then and can't get an answer other than, "We're working on it". It is so unbelieveable that here we have something that a citizen is asking about so as not to unwittingly commit a violation.... they not only don't have this information already printed and available, they just don't know. They never thought about the questions I have asked them, and it sure looks like they like it that way so they can make it up as they go depending on what they find in the next raid. They can come to my house in the night, blow the door, machinegun me into a wheelchair and then wheel me into a prison cell, but they can't tell me ahead of time what is and what is not a violation. They don't know or they don't want us to know. What kind of law enforcement is that?
