Pic related shows when Buffman totally reversed course and started backing the 4SAS4, even flaunting test reports from 10/23 (?) revealing the 4SAS4 was tested to stop 6x 7.62x39 BZ API, but he can't show the test reports! ITAR! Ignore the fact he literally dissected the plate on live video and that the plate is allegedly seventeen years old!

In the retest he only said 7.62x39 mild steel core, but IIRC never retracted the BZ API claim, so there's some pretty convincing evidence to suggest those 10/23 test reports are fabrications or there's something hinky with them and they wouldn't survive scrutiny.

Here are links to the Highcom threads where this was originally discussed months ago. Long read but hugely informative as to the "real story" of how this went down. You will get a totally different tale from reddit.
