For the hell of it, I downloaded ATF Form 1 to see how complicated/annoying is registering an SBR. Other than confirming once again that the process is the punishment, I bumped into something that almost made me choke laughing.
How about NO? May I remind you the notoriously and well publicized way ATF keeps records?
And authorizing ATF for anything other than mass ritual seppuku? Keep dreaming.
Hard pass.
You can always send them a money order…. Or get an 07 manufacturing FFL and an SOT.. then you can file Form 2s electronically and approval takes 2 days… heh heh
5 yrs later they charge your card, it comes back as not valid, they come shoot your dog and arrest you.
