I had forgotten about this thread. I've been busy with other builds and been waiting on tools. I did mange to get them all torn down and am working on cleaning, there is a lot of gunk. Two of the front sights are frozen/stuck and are soaking in some penetrating oil. A couple of small parts needed to be replaced. They are cleaning up much better than I thought and I'm still really excited about building these.
Pic of receivers as promised with DSA barrels, they all hand timed perfectly. The receiver markings are current DSA offerings and I can take close ups if anyone wants.
Thanks for the advice on the buttstock tool. After seeing pics of "Fal spring face", I decided I needed one.
Some may remember my thread on reloading for 6.5 Japanese using Yugo RPK barrel stubs. I hate chucking a good piece of steel that might be useful. So with three Fal barrel stubs, some time and various tools I made my own buttstock tool.
The above is just a quick "see if I can make one" version, with a spare PPS-43 rod. It works. My next version will be more refined.
