I received an email from FPC (i'm a member) in May after they got clarification from the judge saying that all FPC members were covered by the injunction. From the email:
"We're sending you this email in light of today's opinion regarding who is covered by the pistol brace injunction in FPC's case.
If you are receiving this email, you are an active member per our records and covered by the injunction.
Should you have any questions, please contact our customer support team at support@firearmspolicy.org.
Also, please remember to encourage your friends and family to join as well at JoinFPC.org to be covered under the injunction.
Stay Free"
Further developments are very promising though and I've been eagerly awaiting for news on this and the frame/receiver rule. It took longer than I thought, but it's looking very good. Now if we could see some movement on the assault weapon ban that would be awesome.
