What Hoser said. I incorrectly went off into the weeds with my reply because my eyes must have stuttered on the 5320.4 and I read it as 5320.20.

...but my comment still stands, I did a modification and got a confirmation but the ATF never updated their database. So my form 20 failed a year later because the caliber I submitted didn't match the outdated information they had on file.

...the best government that money can buy!
