Part 2

Next I prepared to put the trigger assembly together, I had a factory bolt release that I had modified for automatic release and reblued. I also had a factory aluminum trigger and magazine release that were in good shape.
A quick inventory showed that I was missing the ejector and the hammer strut/spring assembly

So I ordered them up

I polished the mating surfaces of the hammer and sear

As well as the hammer ball end, this is a stamped steel part and they sometimes have rough edges

To solve the issue of the safety detent hole not being deep enough, I trimmed the spring by a couple of coils

Assembled. I tested the safety and it was good to go, plenty of tension on the detent to keep it in place.

I also checked the trigger pull with my Wheeler Engineering Trigger Pull gauge, it averages right about 4 lbs, not too heavy, not too light. I am sure that after a few hundred rounds it will lighten up a bit.

Next I disassemble the bolt and polish the bolt side and bottom, the firing pin & the extractor. 

The barrel and receiver and now blued and we can begin assembling the rifle

Finished!
