MG 42 Receiver Tutorial 5
      Insert the modified bolt into the rails and it should fit loosely and slide freely from front to back. It should
also slide freely into the cam piece.
      If every thing is installed properly the bolt should ride easily through the cam piece and be centered
from left to right and top to bottom.
      Once everything is fitted properly remove and replace the recuperator with the rails installed to make
sure it will fit in and out for service.
      Now we will fit the feed tray and feed cover. Pin the feed tray to the cam piece, it should lay flat, if
not you may have to remove some metal in the areas indicated in red to get it to fit properly.
