I don't, I sold it locally under full disclosure. I'm pretty sure you're correct though. I made some aluminum shims and found that at about .040" thickness (IIRC) it wouldn't jam anymore, but if the mag got manipulated and the rear came down, the bolt would pass over the next round. There was a fine line with the tolerances, possibly an inlet angle : feed ramp issue?
They sent me videos of their tech running the bolt at Mach Jeebus and firing the 12 function test shots in the test facility with seemingly no issues. I told them to have him run it like an 11 year old girl that will be shooting the gun and it will jam, or eject one that he's chambered and show the polymer tip in the video, because it will be smashed. They offered neither.
