My question is, are there any other parts that are compatible with the MP40?   I haven't compared parts side by side nor put a micrometer on it but some parts look similar - barrel nut, sling ring, etc.   Perhaps with a little fitting the sear could be modified for use in the MP40?   Can I use any of the pins, springs, etc on the MP40 or even a STEN?    Just don't have the room to store parts that are of no use to me.

As always, your advise is appreciated.   

When I'm reassembling my MP40 using an FBP bolt, I'm having issues getting the buffer to sit in the slot/depression in the back of the lower receiver.   Obviously, if it's not aligned properly the bolt will not fully cycle.  But what's the trick to getting the buffer to fall into the hole and be correctly aligned?   I've tried holding the gun muzzle up and shaking the gun trying to seat the buffer but it's hit or miss.  After attempting to seat the buffer, I release the Receiver lock screw pin and attempt to cycle the bolt.   If it's not aligned, the bolt won't cycle and then I have to start the takedown process over again.  I've tried standing on one leg and even closing one eye and whistling dixie but am still frustrated.   Yes, that's a joke but I'm seriously asking how others reassembly and get the buffer seated correctly the first time.

Appreciate the replies.

My first post on this Forum (re: picking up a Thompson SMG):

was so successful that I'm back for more. 

This time around I'm in the hunt for a nice representative example of a World War Two MP-40 and - as was the case with my Thompson purchase - I would greatly appreciate your input. I'd like a C&R eligible (transferable directly to me) example that I can put an occasional magazine through.

While an all numbers-matching numbers piece would be optimal, my understanding is that those are not often found - even in the case of WW2 bring-backs - so I will likely have to relax my expectations a bit. 

To start the conversation and to establish a frame of reference, what are your collective thoughts on this one with respect to price, condition and collectability:

Naturally, if anyone has - or knows of - a nice MP-40 for sale, I would appreciate hearing from you.

Thanks in advance for your thoughts and input,

Original German WW2 MP38/MP40 Leather Sling | eBay

1. In the white. As turned.

2. I have capability to cold rust blue. Very pleasing and durable finish.

3. Black nitride (aka Nitro Carburizing or FMC Black) Increases surface hardness and wearability along with corrosion resistance

If you want a barrel give me a shout at the shop by phone or email so I can determine if additional blanks are necessary Hope to be starting an MP40 category on the website (maconarmory.com) soon. Looking at making replacement barrels, sears, and resting bars at the moment. I will list stripped barrels initially and complete as a special order....and I will be confirming function in multiple MP40's

I may have limited availability on front sights, front sight bases, buffer recoil spring bodies, muzzle nuts, firing pins, split rings, barrel nuts, (2 and 6 flats) and the safety ring, and barrel loops. This availability should improve as I am looking at a new machine suited to producing small parts faster than my large 4 axis mill. hope to have the first batch of barrel done late March early April

I’m thinking my extractor may have gone bad?

Can anyone suggest a source to purchase several spare extractors?

are the tubes the same?

I just realized I forgot a number...asking $250 but negotiable....will always trade for parts. I'm looking for a center section to complete a third reweld set.....have a nice nose piece....looking for a piece that is cut at or under rear magwell band to about 1.5 inches from the locking tabs at the rear. I have Rear sight base so no worries if it is removed.

Recently I saw a video (mattexplodesstuff) on Instagram of him shooting his new to him mp40. He mentioned the mags were expensive. This put me down a rabbit hole of understanding what value I had with my mp40. 

It seems like these parts are pricey. I looked around gunbroker and didn’t see any parts really changing hands. The further searches led me here. 
 

My questions:

Is there anyway to make it shootable legally? Maybe in a semi auto with SBR classification. I won’t be getting an SOT anytime soon  

Is there a need for good conditioned parts?  Outside of the barrel (the rifling is in good condition) and front site having matching numbers the rest of the gun is not.  

Anyone in need of a display piece? 

I would be more happy getting it to someone who would appreciate it and freeing up cash something else.

He claims it is "a genuine MP28,II" and babbles on about its "authentic service use" but the barrel shroud is clearly from a Lanchester and for some unknown reason the builder welded the mag housing to the receiver tube/shroud.  Frankenstein's monster was less of a hack job than this thing.

Was offered 17k by a dealer 

Had someone interested at 20k
