NFA

On occasion of getting fingerprinted for the first time, I got to thinking about SBRs. Specifically, if it's possible to register an AR-15 lower in multiple calibers and have multiple short-barreled uppers. Of course that's a popular question, and the consensus seems to be that for each short upper, one needs to have either an SBR lower or a pistol lower, otherwise the ATF might find that one is in possession of an unregistered SBR. One forum post has a letter from the ATF expressing this opinion (which is hardly the letter of the law, but it might as well be):

Dear Mr. :

This refers to your letter of January 22, 1999, requesting information on the legality of possessing a registered full auto AR15 and also possessing one or more semiautomatic pre-1994 assembled AR15 rifles. You appended a number of specific questions relating to this subject which will be answered in the order received.

1. Is it legal to own both?

There are no provisions under the Gun Control Act of 1968 (GCA) or the National Firearms Act (NFA) that prevent an individual from possessing an AR15 registered machinegun and one or more semiautomatic AR15 rifles at the same time.

2. If legal to own both, which spare parts for the registered gun can you also own?

Any weapon which shoots automatically more than one shot, without manual reloading, by a single function of the trigger meets the definition of a machinegun in section 5845(b) of the NFA. An AR15 rifle which is assembled with certain M16 machinegun fire control components, and which is capable of shooting automatically is a machinegun as defined.

The definition of a machinegun in section 5845(b) also includes any combination of parts from which a machinegun can be assembled if such parts are in the possession or under the control of a person. Thus, an AR15 rifle possessed with separate M16 machinegun components can meet the definition of a machinegun, if the rifle shoots automatically when the components are installed.

The fact that a person lawfully possesses a registered NFA firearm does not grant authorization to possess additional non-registered firearms. A person who possesses a registered M16 machinegun and a semiautomatic AR15 and a separate quantity of M16 machinegun components could be in possession of two machineguns.

We advise any person who possesses an AR15 rifle not to possess M16 fire control components (trigger, hammer, disconnector, selector, and bolt carrier). If a person possessed only the M16 machinegun and spare M16 fire control components for that machinegun, the person would possess only one machinegun.

3. Is it legal to use the upper receiver off of the semi-auto AR's on the registered AR if they are different lengths and calibers than listed on the Form 4's?

Before changing the caliber of a registered machinegun you should notify the NFA Branch in writing of the proposed change.

4. Can you have several short barrel uppers (less than 16 inches) for the registered AR and still own semi-auto AR's?

The definition of a firearm in section 5845 of the NFA includes a rifle having a barrel or barrels of less than 16 inches in length. An individual possessing more than one short (less than 16 inches) barreled upper receiver for a registered AR15 machinegun along with one or more semiautomatic AR15 rifles would have under their possession of control an unregistered short barreled rifle, a violation of the NFA.

5. If you change the barrel length or caliber do I need to notify your office if the change is not a permanent one?

This question was answered under Question 3.

We trust that the foregoing has been responsive to your inquiry.
If we can be of any further assistance, please contact us.


Sincerely yours,

The one pistol lower per SBR upper is a pretty ingenious solution.

I also found an SBR FAQ arfcom and an NFA FAQ on mdshooters.com. The latter has a bit on Pre-May dealer samples which was enlightening:

PreDealer guns are different. A Class III (SOT holder) can buy PreDealer guns, while these are cheaper but, they are not much cheaper. They are normally 2/3 the price of a transferable version. But once a SOT gives up thier license he/she may keep the Pre Dealer samples. They can not be sold to anyone other then a dealer or manufacturer when the owner is ready to sell them. People jumping through the hoops & paying the $500 yearly, to get thier SOT to buy these guns. It's worth the effort and cost, you can easily save thousands quickly on a couple guns.

Apparently the source of the Pre-May samples are MGs that were imported after 1968. Guns that were imported as semi-auto after '68 and then remanufactured in the U.S. and registered in the NFA are fully transferrable.

This NFA shit is tricky.
