Frankly, I think that TPNES should just take this all the way and openly challenge the press conference by sending the AG's office a letter stating that he and many other's are continuing to build AR15's on new lowers and that there isn't a damn thing she can do about it because her press conference isn't written into law.
Attach a list of all of your clients to the letter and see what happens.
If nothing happens, then we're pretty much in the clear. If they come after you and your clients, then you'll win in court and a new precedent shall be set.
What's up with all these people that have been around for years, never post and now come in hot with these posts that make no sense.
