Progress Report on Zero Percent
Things are starting to gain momentum. This week I finalized the jig design and started milling jigs. I also made all the tools and plates included with the jig, except the templates.
Additionally I started producing the ejectors since it is the one part that is needed to actually finish the receiver.
I am hoping to get the jigs to heat treat by the end of the week if all goes well.
