Posting here from sunny (well not at the moment, it’s raining) South Florida. Finally decided to post after lurking and gathering information.
My base rifle is a Colt LE6920. It was shipped with MOE furniture, but I soon ditched the MOE handguards and put a proper free-floating quad rail in their place. I also have an EOTech 512 HWS and Magpul AFG mounted to it. The can is a Specwar 762 with the Silencerco flash hider and is currently in ATF jail, though I get visitation fortunately.
Curiosity got the best of me and I called the NFA branch a few days ago. I was deliberately holding off on doing so because I wanted the “surprise” of a nice phone call from my dealer. However, with the news of the 41P delay and so on, I called in. Went pending on 8/21/2014 - hoping to have by January-February.
