My C Products 14-round and 25-round mags feed just fine. I also have a C Products 10-round 7.62x39 mag that is probably 99-ish%, which I find acceptable for bench work. The only difference I see between the 10-round 7.62x39 mag and the 10-round 6.5 mag is the follower; rib patterns look the same on both mags.
I believe the interior dimensions of the pmag will be too narrow to accommodate the 6.5 round. If you compare a C Prod 6.5 mag (or your 6.8 C Prod mags) to a standard GI 5.56 mag, you can see the difference in rib depth--the 5.56 ribs protrude deeper inside the mag. I assume the pmag duplicates the interior dimensions of the GI mag. I have a Lancer 20 that probably has similar interior dimensions to a pmag, so I can test some 6.5 rounds in that and report back. However, I think your best bet is C Prod mags (if you can find 'em), AA mags, or Ammo Storage Components mags.
I hope others here will chime in with their experience.
