@andr3 everything you listed is 8.75 be curve. Dillon NIR is the same base curve. But the active ones, or the non polarized ones they sell blanks for are only 6 base curve and won't fit those models for sure.Dillon donors (I believe all of them), have basecurve 8. Not quite 8.75, but close enough. There are many donors for X-Metals, among them Drake, PHX, Colt, and a bunch others.
Yes, there are 2 types of Dillons, but they actively sell the NIR. If you want real matte, stick to NIR.
Not sure what's the bc of those Oakley frames you listed. I think 8.75, but not 100% sure
