Well I was very pleased earlier, shooting the PPSh in the garden. Then the whole front assembly (barrel, heatshield, metal part of the reciever) fell off the front of the gun, dropping the drum mag in the process. I've put all the bits together once already, and it seems ok apart from the whole assembly is now very loose and has about 0.5cm of wobble in it forwards and backwards. If i 'break' the gun to get access to the inner barrel etc, the whole part slides off. I've dry fired it and there's no full auto, only semi.
When I put it back together, i attached the little black plate shown here to the wooden stock, and fitted the metal part of the fire selector so it would slide backwards and forwards in the hole on the plastic plate.
This image shows a plastic part which fits in under the gearbox but after the fire selector has been placed. The second hole from the left has a screw in, which goes through the fire slector plate as well. It looks like there could be a circular disk missing from that screw area because there seems to be a glu residue left behind.
The parts:
Does anyone know how I could fit all this back together/ has anyone had the same issue? 
Cheers in advance guys
There is indeed a circular metal piece with a threaded hole in the center. I might be in your garden or if you can't find it, i think you can have one easily machined.
I'll have a look, thanks very much 
This is the HP model isn't it have seen this problem before.

Yeah its the HP one, is it a relatively common problem then? Do you know of a solution so it doesnt do it again at all?
Cheers

Try a search from about 18 months ago or so, I thought it was the same gun again when I saw your post.

Yup, that disk is essential.
If you can't find it then you'll need to replace it. Luckily it's not too hard to make a disk with a threaded hole in the middle. It doesn't even have to be a disk really... plus Halfords sell an inexpensive tap and die set.
(Ok, not as inexpensive as I remember... but still a very good kit to have in your toolset... I use mine loads... http://www.halfords.com/webapp/wcs/stor ... yId_165572 )
You could use a washer and solder a nut onto it 
if you can solder and it will fit in the space nice cheap fix.

If I remember right from my own then yes that should work.
I also remember thinking what a stupid design and a weak point it was when I first took the gun apart.
