MG 42 Receiver Tutorial 3
Now we will fit the buffer, the receiver was a little tight in the rear so I polished off about .010" from the area
shown in red in the second photo.
Next step is to fit the cam piece, you will need to square the corners of the cuts in the receiver for it to fit
properly. It should fit snugly and rest flat on the receiver. There was a small bulge in the center that I ground down
to get it to fit properly, in this case it was only about .015"
The 2 parts should fit together tightly with no gap between them. The rivet should slide in
easily. The part also needs to fit on squarely for proper alignment of the feed tray and cover.
