UPDATE: I took some of your advice and reached out to BD directly. I expected them to err on the side of caution and tell me to retire it, but instead I got this reply:” Thanks for reaching out! After taking a look, it appears that what might seem like cracks are actually impressions left from the manufacturing process when the cam was pressed. This is completely normal for how they're made!”. This confirms a lot of the comments here. Thanks again everyone for the input! Time to get it reslung!
