Counterfeit or qc?? - JP Enterprises 308 Enhanced Cam Pin

I bought this product a few times from OP. Upon comparison they seem to be 2 different qualities and or finish and one is even missing the jp logo that should be on top of pin. Same shape and dimensions btw. It has been a while since purchase so I’m sure return is out of question but I am worried about a part that should make me feel more confident in the critical parts of the rifle. Not sure if it’s a qc problem with jp or mislabeling from OP.
