Hello 93x64mm
Thanks for the reply.

Unfortunately RCC is running 3 - 4 months delivery. I can't wait that long ... I'm too old.

I've ordered some more 5.6x61R brass and will modify them, but this time with a very narrow extractor groove.

I also posted pictures of my friend's rifle. It is nearly identical to mine with a few differences. I hope to get as much info about his rifle, as I did for mine.
