Hello everyone. I just bought a very nice, all matching, MP-40 parts kit with a cut up receiver. I'm trying to decide what to do with it. I'd like to either make a dummy gun out of it or have someone do a semi-auto build. Does anyone know a licensed person who does semi-auto builds? I know I'll either have to have the stock pinned or SBR it. I figure if someone who is licensed makes it it'll be done right and I'll be able to sell it one day (since I didn't make it myself). Otherwise, I'll just try to find a good dummy receiver. Thanks in advance for your opinions and input.

IS, the receiver cut in such a manner that it could be welded together again?

IF SO, you have the makings of a post sample machine gun, but only a SOT/07 could do the restoration, it may be more valuable as a kit in that situation rather than a Semi.

For historical reasons, that kit could live again, going from SOT to SOT, in a semi, its dead forever, and honestly any MG's turned into semis, tend to be quite boring.

My advice is to enjoy the kit as a kit. Treat it as a reference piece where you get to study it. You will regret doing anything to it that reduces its value both in historical and monetary terms.

I am not familiar with ATF mp40 approved dummy gun designs. A dummy gun would probably be preferable to a semi build. Closed bolt semi autos builds using valuable original open bolt smg parts require heavy modifications of the internals.

You would be better keeping the kit as a reference piece and buying a GSG 9mm pistol to shoot.

Its not always about getting the most amount of money, that's my point, Semis are silly, I SBR'd my Chuzi because it just looks STUPID with a 16" barrel, same as PPSH or any other with a long barrel sticking out of the barrel shroud.

Good kits, especially ones that can be welded, saving the original receiver are worth more to history than a chopped up mutt.

I would put it on a dummy receiver and hang it on the wall, retaining the cut receiver and any other unused parts, because who knows what the future holds when it comes to firearms laws. I have faced the same situation with a Sten Mk. III kit from the 90s. I handled it by leaving the kit in the box and subsequently misplacing it. I don't know where it is right now, and that is not a "boating accident" cop-out. Perhaps it will be found, along with a toaster oven that went missing in 1975, when they do my estate sale. ;)

Sure, send in a demo letter to acquire an MP40 and let me know if they approve it? Not happening. We're in probably phase 3 of "culling" of the "have fun postie" world. Essentially every post sample made is to be used for gov. purposes....thus eventually gov. property, the receiver anyhow. Notice they reserve the right to check on their stuff 24/7 in some cases without notice? That does not happen with transferable guns which are "privately" owned.

They took a lesson from licensed European collectors. They quit issuing licenses for the most part and as the guys die off the guns get cheaper and cheaper.....until they are gone. They are patient. Not sure what phase 4 will be, but the vast majority of 02/07's today have no skills or equipment and will likely be means tested like the zoning rules they invented 10-15 years ago that gutted 01/03 dealers. If you think they are not wise to the "no letter postie business" and don't have a plan in motion to curtail it, you are in the "not so smart" category. It's been an industry joke for years.

Thats a lot of assumptions right there. Been hearing that stuff for years. Since the ATF's ability to make stuff up got a severe blow a few days ago I wouldnt be so sure about the ATF unilaterally putting the kibosh on no letter transfers. Theyre still going through like usual. Picked up a nice STEN last week for a grand

I'll admit that a lot of 07/02's aren't in it for real but I wouldn't call it a majority and absolutely not a vast majority.

Heres a nice MP40 I just built from trash

How did you convert the internals of the MP40 from a bolt fired gun to a hammer fired gun? The ATF requires that bolt fired guns can no longer be made and are illegal to make. The gun must have a hammer fired mechanism as means if igniting the primer.

A lot of open bolt MGs are converted to striker fired. That's probably appropriate for an MP-40.

OP, Here's a starter kit but it will still take a lot of work. MP-40 Semiautomatic build kit
Or you can do a blank firing full auto. MP-40 Blank Firing Only Build Kit

Also, look on the builder's forum right here. https://www.gunboards.com/threads/mp-40-semi-auto-building.375012/

There are semi-auto MP-40s available to purchase. I don't know how good they are but they would be cheaper and easier to get than a custom made piece.

It's your parts kit and your money, do what you want with them.

I would assembly the parts on a blackened aluminum receiver for display without modifying any of the parts and keep the leftover original parts safely stored away. Treat the kit as an investment. It will grow in value. Enjoy it as a dummy gun. If you are able to save enough money, sell the kit and add it to your savings to get a working MP-40 or other worthy investment grade firearm. Your investment will grow, and additionally you will be able to shoot the new firearm. More fun 4 U.
