I just got a Form 1 (SBR )approved in 1 1/2 weeks! I know some others have had a similar result, but in the last two years it has taken up to a year and involvement of my Congressman to get multiple form 1's (SBR's) approved. Also, the ATF actually e-mailed me today and asked for some more photo's of the receiver (it confused them a little because I built the receiver myself, and didn't just cut the barrel on a commercial firearm). I e-mailed with the ATF back and forth today, and just got the form approved. A year ago I would have waited 6 months and just got a "disapproved" asking for more pics. Look in the vintage forum for my latest build of an Erma EMP "sub-machine gun" (NFA registered semi-auto SBR).
