I have started the new tutorial for doing the receiver reweld with my weld jig.
Here is the link: http://www.projectguns.com/mg342.html
I am redoing all the photos and need to get a couple more parts to finish the receiver so it will take a couple of weeks to complete.
As soon as it is done I will also do one for the bolt and grip. TNW sells a kit with all the parts you need to do the bolt and grip and the trip lever. it comes with drawings and instructions. It is $180.00, a real bargain. the trip lever is not in the photo.
use this thread for questions.
