My first one and I didn't have a problem with the process at all! Thank you Sara Jones!
The F1 was sent 10-30-11 and received 11-04-11. The stamp is dated 5-03-12.
Just some notes for other potential stamp collectors..
NFA trust was used
Schedule A had the lower listed
Certificate of compliance was submitted (although I've read it's no longer needed. Didn't hurt to send it in JUST IN CASE)
Congrats on the stamp as mine was approved the same day. As far as the Cert of comply form i actually had to reprint sign in a place i missed and fax to the atf, so my guess is it still is needed as of two weeks ago. luck with ur future build.

Congrats! Mine is dated 5-1, pics??
here's mine i still need to figure out my rail cover situation not sure if i like the xtm's
