Thank you for your input and bringing this defect to my attention.

After comparing the bolt in my tutorial, to those on my other weapons, the ejector on this bolt does in fact sit lower in the ejector pocket. Although I have had no problems with this weapon, I shall see about swapping out this bolt with a quality replacement.

I agree, that extractor snapping in addition to ejector swipe do in fact both cause brass deposits on the face of the bolt. It has been my personal experience that particles accumulated particularly around the ejector are caused by the ejector itself. While of course extractor modifications to eliminate brass shavings would be unwarranted and not recommended, I personally feel chamfering of the ejector face to be a relatively simple task to at least eliminate that particular source of brass deposits.

I feel totally competent in my abilities to perform this polishing task without adversely altering the trueness of the ejector face. But in light of your post, to prevent any complications for our readers who may be considering this, I will remove this tutorial from the forum to prevent the possibility of any “unintended consequences” as you put it.

Thank you again for your input.
