Thanks for the kind words.
The comments in question were copied verbatim from the POI for thr CQB Course. Having said that, and to the best of my knowledge, they never used a "ramped" barrel, and it was my belief- after asking those who taught the course, that it probably meant "polished" but has always been in the POI and no one ever changed it.
I made a note on this on the first draft. However, when working on V3.2, it was lost in the sauce, so to speak.
It was my error, and mine alone.
Sorry for the error.
