Croix de Joan D'arc not accepting Ribeyrolles Optical Kills

I'm gonna go ahead and dangerously necromance this thread.
The medal is still practically impossible at short notice because it doesn't accept Ribeyrolles Optical. Instead you have to unlock Automatico Factory, get 50 kills with it, get 20 headshots with Optical, then you'll unlock Ribeyrolles factory and THEN you can get your 20 kills for the FIRST STAGE of the medal. No one is using Automatico Factory and certainly not with the intent to unlock the inferior Ribeyrolles. The Subsequent stages of the medal also do not specify exact weapon patterns which, worst case scenario, means all 4 stages are blocked behind lengthy, high level, multi-stage barriers.
So much for me trying to unlock every medal. I already got screwed out of Assault Order of LeFever, Support Order of Valor, and Lightning Cross Order when my progress got reset in the middle-end of a week due to purchasing the premium pass...
