Inconsistent - KNS Precision Safety Detent

Inconsistent machining with these. I'm not sure if it's just because they arent changing the tooling as often as they should, or if they are hiring toddlers. Some are smooth, some are ribbed, some are pointed, some are rounded, and some are off center. I'm not sure whats going on over at KNS, but they used to produce some quality stuff. Maybe it's just the pandemic frenzy. Regardless, I don't thinnk these companies should be dropping their QC. If you buy them...buy extra.
