My buddy over at Vintage Airsoft. It's actually a sten that was converted to a Lanchester and is a little kit that will let me switch between Lanchester and type 100.

A mp5 mag rocks in like an AK mag,a sten mag slots in like an m4 mag,is there enough room
To make an adapter to go around the mp5 mag to make it fit the socket in the magwell?

The sten and mp5 magazines are a similar width so I'm finding it hard to make a little adapter. My next plan is to get some aluminum giving and bend it into shape. It will sit in the end of a cut down sten mag and be held on by some epoxy.

Here's my rough plan so far explained in a crap picture.
I'm experimenting with 3d printing too but it's rapidly turning into a PITA

Ok ignore what i said the MP5 mag does not rock in its similar to the sten and m4 style of magwell and catch
Got confused as i have an mc51 which looks similar to and mp5 but is in fact a very short G3 and does have the style of mag
I was rambling about..
Looks like you will have zero space to fit that s shape adapter,and too tight a radius will no doubt stop feeding.
There is an airsoft stirling smg but i bet the mags wont be cheap and will still need adaptation.

Sterling magazines feed from the front as with the mp5 so I'd just be in the same situation. The sten mag well does stick out quite a way so I might be able to get it to work.

PPSh mags look like you could jerry? rig them

If you construct an entirely new magwell housing. that will fit your new mag perfectly have the right
catch,and you could reposition it on the receiver so the hole lines up perfectyly with the hop tube
Sounds easier than done but thats my thoughts on it.

I did something similar grafting an old AK hi cap mag onto a lo cap shotgun mag (don't ask me why ) ...

... The first mag is the combined AK/shotgun mag with a standard shotgun mag above it, then a PPSH mag and then a MP40 mag for comparison.

I used exactly the technique you've described, and it works fine, but I used a tight coil spring instead of the alloy tube to feed the BB's. The PPSH mag does look about right for the type 100, but the feed hole is at the front so would have to be routed with a feed tube like you said. You should be able to do it by cutting the top off an MP40 mag so that it fits the mag well, and grafting a PPSH or MP5 mag to it. The mags I converted were all plastic so that made things easier.

Hope that helps.

The multiple brands of PPSH have different (not cross compatible) mags, could be worth looking into: I just stopped at the first one I found a good pic of

The spring is an good idea. Was it strong enough to withstand loading by a speedloader? My aluminum tubing arrived yesterday but I'm on holiday till Tuesday so chances are that I won't get any of this done for Saturday.

It's a high cap so I never needed to use a speed loader, but I can't imagine that it wouldn't. I managed to find a really tight coiled spring on eBay, whose internal diameter was just right to take BB's, I still have a 10 cm piece left if its any use to you. The advantage of a spring is that it has a bit of give and can be bent to quote small radii.
