One of the particularly popular transferrable machine guns out there is the H&K auto sear. Since H&K grip and trigger assemblies are interchangeable between 9mm, 5.56mm, and 7.62x51mm guns (ie, MP5, HK33, and G3) a single registered full-auto grip assembly can allow someone to effectively have three machine guns for the price of one (albeit only one at a time). However, there are some potentially very expensive and dangerous pitfalls for someone acquiring one of these without a full understanding of the law and the technical details.
In short, an H&K upper receiver that has the ability to fit a factory full-auto grip assembly is considered a machine gun by ATF, just like an AR lower with the third pin hole drilled. If you have a registered standard factory full-auto grip, any gun it can attach to is also by definition a machine gun. Instead, the proper way to do this is to register a grip assembly that is modified to fit onto factory semiauto receivers. This sounds pedantic and strange - and it is - but it is a complex and tricky area of law and ATF rule making. If you are planning to put tens of thousands of dollars into a transferrable H&K, you really ought to have a clear understanding of these issues before you make a purchase!

And he commanded them to make all sit down by companies upon the green grass. And they sat down in ranks, by hundreds, and by fifties. And when he had taken the five machineguns and the two lowers, he looked up to heaven, and blessed, and brake the machineguns, and gave them to his disciples to set before them; and the two trigger assemblies divided he among them all. And they did all shoot, and were satisfied. And they took up twelve baskets full of machineguns, and of trigger assemblies.

    • The ATF is legally required to rule like this, as the parts themselves are plainly either statutorily required to be the legal firearm, or not. This situation exists because the BATF is forced to rule exactly this way by the GCA. Don't blame the ATF, either blame HK or the GCA.

I don't think it's actually possible for the ATF to do the things that Congress has told it to do in a fully logical, consistent way. Their bosses gave them six contradictory rules to enforce, and they're stuck. They haven't exactly done the best possible job of trying, either... but they haven't done the worst they could have done.

    • The ATF has to make decisions about this, and there really aren't good decisions they can make. They're statutorily required to rule on what constitutes a machine-gun, or what constitutes something that could be readily converted (or convert something into) a machine gun. Ruling which part of a gun is legally the machine gun is essentially arbitrary, but you have to do that because otherwise people will just dissassemble them and claim that no part constitutes a machine gun. The problem is that the trigger pack both isn't legally a machine gun and something that is used to otherwise convert a not-machine-gun into a machine gun. Obviously you run into some problems here because they've seemingly chosen the wrong part to consider the machine gun. I mean, they may be statutorily required to consider that part (the upper) a gun, but either way you have to make a decision about that. Gun owners are constantly trying funny business to get around the letter of the law rather than the spirit (see the absolute nonsense coming out of various places regarding totally-not-stocked-pistols), and the ATF is then forced to issue increasingly complicated rulings on what does and does not constitute an illegal firearm. The fact that you have to modify the legal machine gun rather than the legal semi-auto upper is perfectly reasonable: if you modify the legal thing to accept a legal part (the legal part being the legal trigger pack, which is not a machine gun) you have now created a unregistered machine gun. If you modify the legal machine gun you're not doing anything wrong, and you haven't modified the legal semi-auto upper (so you can't have made a machine gun) and when they fit together you've only got one gun, and it's the lower. Could you change all of this by thinking of the trigger pack as the legal firearm? Sure, but I'm 90% sure the definition of a receiver does realistically mean the trigger pack in this case. Yes, this is somewhat silly. Yes, they should change it for this specific example. No, that doesn't mean this is really a problem: blame HK for making a gun that doesn't play well with US law, don't blame the ATF for doing what they're required to do.

    • @@TheFanatical1 It's the statute that's wrong. As Ian has discussed ad nauseam via pistol braces, the notion that a federal agency should be allowed to criminalize and decriminalize constitutionally protected items at will is absurd. Particularly when being afoul of said ruling means committing a felony offense. It also leads to ridiculous things being legally deemed "machine guns" that plainly are not, like shoelaces for instance.

  • I recently bought a transferable Mac-10 and went to an indoor range. The manager there said I needed a second tax stamp because it had a stock, saying it was an "SBR". He showed me his MP5 as an example, I pointed out that he had a registered trigger pack on a semi auto receiver and it was NOT the same thing as what I had. In his case, yes, the MP5's semi auto receiver needed to be SBR'd in the config they had it. He had to save face in front of his employees so could not admit he was wrong. A self proclaimed ATF "expert" that handled all of the paperwork at that FFL w/SOT gun store/range. I know the law can be confusing but like come on man.... lol great video though and one I will show him if he gives me trouble again.

  • Don't forget that there are unmodified registered receiver guns with modified unregistered trigger packs, and if you remove the trigger pack from it you don't have a short barrel rifle but you can't use the trigger pack on another host even though it would fit. In summary, there are three types of legally registered HK machine guns that civilians can own. One, Registered Receiver guns which are the same specs as factory machine guns and will accept all factory parts and trigger groups. Two, registered auto sears or trigger packs. These are conversion devices modified to fit unmodified semi auto receivers. Like Ian said, you have to watch out for the SBR thing. And Three, there are what the ATF refers to as improper registrations. That would be the guns where the receiver was registered but not modified and a trigger group was modified but not registered. This type of conversion is the least desirable as the receiver will not accept any factory machine gun trigger housings and, you cannot separate the trigger group from the receiver and use it on another gun. It's a one trick pony. The reason it's not a SBR without the trigger group is because the receiver is registered as a machine gun, even though it won't accept machine gun parts. But, it also can't be a SBR because you can't legally separate the trigger group from the receiver, otherwise then you have an unregistered conversion trigger pack. Makes perfect sense, right?

    • ​@@MartinsMachinesFJ Vollmer actually did this and the ATF told him no, because modifying the receiver made a second machine gun even if a registered sear was installed in it. I reluctantly admit that the ATF was correct in that regard because the modified receiver would accept a factory machine gun pack at that point. Vollmer rewelded the receivers back to semi auto specifications but was told by the ATF that they were now machine guns even though they had been converted back to semi. Vollmer sued the ATF and was able to show the court the functional difference and won the case. This is one of the times where ATF lost a case they made based on their theory of "once a machine gun, always a machine gun"

The Supreme Court ruled in Haynes-v-US that felons cannot be expected to apply for NFA registration because it violates their 5th Amendment rights against self-incrimination. That's right, the NFA is only ever used to charge otherwise upstanding and rule-abiding citizens. Career criminals just get the same "felon in possession (of a firearm)" charge regardless of type (or even just for ammo). There are some potential enhancements for that charge, but they're primarily about how the gun was being used or what else the possesor was doing at the time (eg: used in a crime, or along with drug possession, etc...).

  • There's also "mated" sear packs and "uppers" - I remember back in the day it was possible to get them 'separated' if the sear was registered - you didn't get two machineguns out of it, but could then use the sear pack in another host. All my HK NFA toys though, thankfully, aren't that convoluted, and all the 'hosts' are registered SBRs as well.

  • If you have a registered sear in a host with a barrel less than 16” and a stock, as soon as you remove the registered sear you have a SBR. This is why most hosts are also registered as SBR’s too. (Or should be). There are also registered receiver guns where the receiver is a UN-modified semi-auto (clip on lower NOT swing down) and the modified trigger group/auto sear is not registered. These guns you cannot remove the sear from the host without having a un-registered machine gun. Before 1986 these HK sear machine guns were very expensive for the time (about $1,000 NOT including the $200 transfer tax) You had the cost of the semi-auto HK94 for $500 plus the cost of the sear, plus cost of gunsmithing to modify the trigger pack and welding up the semi-auto bolt carrier (full auto mp5 carriers were not readily available then). At the time a registered M16 from Colt was $500 plus tax. And new Cobray M11 nine’s were $150 plus tax. 99% of transferable “MP5’s” are registered conversions of HK 94’s done by Vollmer, Fleming or S&H in the 1980’s. Real original all German transferable MP5’s are super rare as they had to be made and imported PRIOR to the GCA of 1968.

  • Pretty solid video on the subject. It definitely is a little complex. It get's really fun when you have multiple host guns that have different barrel lengths and you have to be careful about how you take them apart and assemble them to make sure you don't make an SBR by accident. Also, you can have a two-pin upper receiver if you don't have a full-auto carrier/bolt and the receiver is modified to ensure you can't insert one (receiver block). Conversely, you can have a full auto carrier and bolt in a semi auto gun if it has a shelf and not a second pin. Basically, as long as it has one of the two, you're in the clear. All my hosts have full auto carriers and bolts, but they also have shelves/no second pin hole. Generally, the only thing I have to swap if moving from gun to gun is the ejector on the pack.

    • AOW - A catchall category of NFA stuff that covers "concealable" guns that don't meet the definition of non-NFA "pistols", "revolvers", nor fall under any NFA category. One of the most common ways to "accidentally" make an AOW is to add a vertical foregrip to a legal handgun, because (according to ATF's purely administrative and unilateral judgement) the definition of a "pistol" or a "revolver" only allows ONE vertical grip - the normal pistol grip. Thus, a "pistol" you have a VFG on is both "concealable" (less than 26" long overall) and yet isn't a handgun. Yeah, bolting that $10 airsoft grip to the accessory rail of your Glock or Sig magically makes it an NFA item.

    • There are actually three variants. Registered push-pin machine guns. Registered trigger assemblies and registered sears. The distinction in the latter two is which part carry’s the serial number the sear or the trigger group. Based on that it also informs which parts can be replaced… if you break a registered sear, you can’t replace it. The pack is also modified for use with a registered sear (sear, hammer and springs). If you break a part in a registered trigger group, you can replace any part in the trigger group with a factory part - including the sear - which is the registered part in a registered sear!

When I got the gun I realized that not only was there no HK sear in it, the serial number was just electropencilled on the frame in a place hidden by the detachable stock. The gun traced back to Bill Fleming, who was then in jail for various shenanigans. I sold the gun soon after since I was uncomfortable owning it but I'm sure it's still out there somewhere.

  • Great video and did clarify a lot... however, it brought up a question that it then didn't answer. You said that the bolt in a semi-only gun is also different than a full-auto bolt. So in the case of a transferrable full auto trigger pack that has been modified to hook onto unmodified semi-only guns - how does this enable full auto if the bolt also needs modification to work with the trigger pack? Wouldn't the gun still be semi-auto or not function at all? I'm assuming that the trigger mech internals have also been modified somehow to use the semi bolt? Does that mean they no longer work with a full auto bolt?

He also didn’t talk enough about “marrying” a sear to a gun - you might be able to move that pack to another gun - but not if it’s married because that as he points out created an unregistered SBR assuming the upper started life as a rifle. You could see in this cash that the upper was also a registered part, probably married to the sear in the clip on pack, based on the S&H manufacturer engraving on the back left of the receiver. But maybe it was registered separately as a SBR… confusing stuff!
