M1C/M82 experts????

So - you are saying both types of Adjustment Caps are correct, and the difference is appropriate for sn# 40,6xx vs sn#42,7xx? Un-numbered Knurled Caps are correct, and not just taken off some commercial Lyman Alaskan?

I have people telling me that "all" Eye Cups should be numbered. You are saying that is wrong?

Thanks for replying.
