So far I have an M60 trunnion that is about 80% complete. It will need some corners rounded off and a bit more milling and drilling. No modifications need to be made to the trunnion for the semi auto M60 build.

I have the sheet metal lower channel, complete. Only a minor slot needs to be cut in the bottom for the semiauto trigger linkage to pass though. I will show more and explain more with the photos.

I still need the rail set, bridge and rivets to finish this receiver. Its also good to have the yoke and even the bolt when assembling to make sure everything is in the right place. I will need to get these parts as well before assembling.
There are block off plates that need to be welded to the side rails to prevent the full auto M60 bolt from fitting into the receiver. This can be a welded on or if you mill the rails from scratch you can simply leave this material in place. I will most likely buy a set of 80% complete rails or a finished set of M60 full auto receiver rails. Either way I will weld on the bolt block offs. I have blueprints to mill a set of rails from scratch but to save time I will likely buy them or finish a set using the prints.
Hopefully by the time I'm assembling this receiver I will have some other parts to test fit as well. I don't want to get it built and find out that the barrel doesn't fit the trunnion or the barrel locking pin hole is to big or to small. Anything is fixable but I will try to have on hand most of the bolt and barrel assembly parts when riveting and welding the final receiver together.
