so I'm from Canada and I enjoy building airsoft guns as:

1) majority of US legal firearms are prohibited in Canada; and
2) I believe that factory full-auto firearms in the US are classified as machine guns and thus one cannot own them anyways without breaking bank.

I have a few MP5s in my collection by the company VFC and from what I've heard, the HK MP5 trigger packs and lowers are a drop fit on the airsoft upper.

if I were to purchase a full auto trigger pack or entire lower from HKParts, do I need to make any modifications to the trigger pack for it to fire on full-auto? I read there were some complications on the full-auto sears but since it's already in the airsoft trigger pack, it should be fine right?

edit: for clarification, all information that I wish to obtain is for airsoft- to mimic the function of real HK firearms

No one here is going to tell you how to make a machine gun.

^ I guess what I am saying is that the current airsoft MP5K can already fire in full auto. assume that the FA trigger pack or lower from HKParts is a drop-in fit. when the airsoft upper and HK lower are assembled, will it fire in full auto or will I need to switch the auto sear from the airsoft one into the HK one?

Read the rules, especially item #6 from the top. No airsoft discussions.

I had no idea Airsoft and real HK trigger packs were so interchangeable!
All I can say is Wow... Just Wow.

That MP7A1 jumps out at me.

A real MP5 and an airsoft MP5 work entirely different.

Airsofts don't have bolt carriers to cock the hammer. Two completely different animals and probably a waste of money. I thought you guys could get Mr762 and MR556'S up there? P7's etc?

let's take a look at the BCGs of the HK416C and MP5K and the MP5K trigger pack that I have:

added UMP and G36 BCG

So those bolt groups and trigger packs actually work with your airsofts? I'm sure it's possible to make them fit, but do they function? My son's HK airsofts function nothing like the real deal. You just have to understand that people are leary of telling someone how to make a full auto pack fit to anything other than a registered sear. If legal to order in Canada, I would just do it and make sure you're within your legal laws.

thank you for the constructive response. I understand the concern over the FA function and its legality.

to answer your question, the airsoft guns themselves are gas operated and can replicate the real mechanism to a degree. however, most of the internals are made of aluminum or pot metal and wears out quite quickly over repeated use. replacing them with swappable HK parts would undoubtedly strengthen the structural integrity. not that I plan to use them at games, but they can prove to be effective training tools.

Right on then. It's your money and if they work better for you and it's legal, I say, "go for it".

The thing you won't get here is how to possibly convert a semi to full auto, it's a very serious question in any Western world. Sothat part of the conversion will have to be left up to you because of the possible sketchy feelings people have. Sorry we can't help in that regard but it treads into an area that no one wants to get in to.

People get apprehensive about possible legal issues involving the American BATF. There are agents phishing for shady characters in the interwebs. Be safe and stay legal .
