I had a lawyer draw up my NFA trust. At his advice, I transferred my MGs into the trust using form 4. One of the transfers was returned because of errors. This was for my AO Bridgeport M-1. The ATF letter stated that the original registration lists no barrel or overall length for the firearm and for me to send a written memo giving this information. However, I'm looking directly at my original transfer papers and it does indeed list the barrel length as 10.5" and overall length as 32". Do any of you have a possible explanation why the ATF is requesting a memo on this? My Savage and my SBR went through just fine. I'll give the examiner a call on Monday, but thought I'd run it by you first.
