How to Avoid the Legal Pitfalls of a Transferrable H&K Auto Sear

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!

Stroking my chin with $147 in my bank account: “This is important information for me to know.”

The miracle of multiplying machineguns: you disassemble one machinegun and voilà you have two machineguns now.

Schrodinger's' Machine gun, it's status depends on what benefits the ATF most.

1 gun = 2 machineguns makes perfect sense

'Everybody ought to have a full-auto MP5. They're awesome!' -- my new favorite Ian quote

"If you think you understand quantum physics, you don't." It also applies to ATF regulations.

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.

Thanks for the explanation Ian! There’s thousands of guys who are kicking themselves for not buying a transferable sear pack way back in 1986…..

The BATFE laws are more convoluted than anything Heckler and Koch have ever made 😂

For some reason, "This is a gun and this is also a gun.", reminded me of the scene in "The Unit" where the blindfolded potential recruit builds more guns from the parts on the table than he was told would be possible.

Now I need an emotional support MP5 😭

"Now I have a machine gun. Ho ho ho."-Best Christmas movie of all time.

Moral of the story... NFA is a train wreck.

Repeal the NFA
-
I live in the UK and I'm poor as heck, there's zero chance I'm ever going to own an MP5, still found this video fascinating!
-
That's a lot of words just to say repeal the NFA... Good info, but they make it vague so they jam you up whenever they want.

Listening to Ian talk about HK machine guns on a Monday morning at work while doing payroll and paperwork. So soothing.

Great content Ian

Thanks Reagan

Crazy how a piece of metal or even plastic can get you up to 10-30 years in prison
