Interesting that there are not comments here yet... To me it looks like a MIM casting artifact with the circular part below it being the injection point and the pattern above possibly a result of binder contamination. It could indicate a weak spot or not depending on whether the sintering process cause the particles to rebind or not. The only ways to tell would be to x-ray it or whack the circle with a punch and hammer to see if it pops out.
I'm glad you commented! I did a NDI on it after discussing with some friends and coworkers. Ultimately FN replaced it. I've got about 700 on the new one since then. Since this video was made, I've started a new career and moved to a different state lol. I'm slowly getting back to video production and catching up with follow ups.
