Yes, you wrote this and you were incorrect.

As far as unregistering it, once the reciever is an NFA item, it is that way forever, and is subject to all of the rules regarding out of state transit, transfer of posession, and posession, so there is no registering and unregistering the reciever no matter what barrel it has. The only way that will satisfy the ATF that it is no longer an NFA item is if you furnish proof that it is destroyed. Sounds drastic, but that was straight from an examiner at the NFA, and a local agent at the Boston Field Office.
Then this was added by another forum member
The examiner you spoke with and your local field agent may want to review

Section 2.5 Removal of firearms from the scope of the NFA by modification/elimination of
components.
Firearms, except machineguns and silencers, that are subject to the NFA fall within the various
definitions due to specific features. If the particular feature that causes a firearm to be regulated by the
NFA is eliminated or modified, the resulting weapon is no longer an NFA weapon.
When I initially called the ATF I was told a couple different things by different people that do not specialize in NFA items...when I pressed the subject and was sent to an NFA specialist I got good information and felt confident enough in the answer to move forward with my project. Let's all try not to pass on poor/incorrect information to limit confusion in an already confusing area of our hobbies!!
