I know that my findings don't mean the cam is unusable. I cheaped out when when I an extra 100 bucks could have gotten me a brand new Lunati. I read many recommendations on here for reground cams on Magnums, and the seller had 100% rating. I'm regretting the decision, as I have little faith in the quality if they were this far off on the quoted size. I may be stuck with it though, as I bought it in mid January. eBay's resolution period has passed, and it PayPal just redirects me back to eBay.
By the way, anyone have a spare lifter retaining clip? Mine took flight and disappeared when I removed it.
