Unregister an NFA item?

[Reagans Rascals]

I was wondering since weapons such as the KAC PDW and the HK MP7 aren't available to the civilian market, if it is possible for an 07/10 FFL/SOT to purchase those types of weapons on a demo letter or as an R&D item and then to permanently render the weapon semi-automatic only and then to essentially unregister it from the NFA registry or somehow transfer it to Title 1 status and therefore be capable of selling it to a civilian.

I understand the weapon in question, would be expensive to the point of unobtainable once available to civilians, but I'm just asking in hypothetical if it is indeed legal for a post-sample to be unregistered from the NFA registry as a post-sample once it is rendered a non-machine gun.

I would assume the Class 2 could render it semi and then re-serialize it as a custom weapon... and then offer it to the public as their own "creation"... is this correct?

Basically if I was an 07/10 FFL/SOT could I purchase an MP7, render it semi-automatic only, re-serialize it, and then offer it as a factory SBR to a civilian?

Once a machine gun always a machine gun. You also cannot remove serial #s.

Just speculating:

The only possibility I see would be destroying the receiver, remove from NFA regulation, and then rebuild with a new, SA only receiver.

But I bet if you did too many of them ATF would shut you down. Faceless .gov minions dislike clever people exploiting loopholes in the system.

Most full-auto guns cannot be converted to semi-auto without extensive and complicated machining and such. I doubt it if the ATF would be willing to "un-register" a F/A firearm and let it be sold as anything else. Otherwise there would be a lot of converted M249s and M240s for sale as well as S/A open bolt guns would still be legal to manufacture ad sell.

I would just wait until a S/A version is made available and SBR that.

In regards to the de-mil route, those Bren and DP-28, etc. parts kits that are sold online are full-auto weapons whose receivers have been de-milled to ATF specs and are then re-built as semi auto rifles. Essentially, the receivers are scrap metal that was once a machine gun, and the builder is making a new weapon out of that scrap.

I'm not sure how that would work with KAC PDWs, MP7s, M-16s or 249s, but I imagine it would not be cost-effective or practical to rebuild those destroyed receivers.

I'm sure there is some ATF regulation that I'm not aware of that further complicates the process as well.

Any parts kits de-milled overseas and then imported would also be subject to the barrel ban.
