Hi Guys,

Kurusu, you have a keen eye, my friend.

I totally remade the last three parts that I had previously accepted as being OK - the bolt housing block, the "Geladen" indicator and the ejector spring. Springs are not particularly well handled by today's solid modelling programs, especially leaf springs as their movement is so complex. I had to create fixed geometry that matched the shape of the part as it would be in situ. I cannot drive the shape with mating constraints.

The depth of the cut-out in the frame for the magazine ejection button was my error, and was 0.2mm (nearly 0.008") too deep. That is why the button was sitting flush and not slightly proud as it should have been.

Here are the subtle effects of the changes I have made (thanks to Kurusu):
