I think the AMD-65 bolt carrier is based on a milled receiver bolt carrier. There is a fairly rare version of the Romanian 7.62x39 bolt carrier that is tapered and rounded on the bottom instead of a flat bottom. I think these should give the narrower magazine openings more clearance.
No Hope For Me
I reprofile almost all my carriers to closer resemble the m70 as they run smoother over the hammer and the mag. .. I know a normal rommy will not work on a bulgy mag but I just milled it narrower. it likley could be done with a hand grinder and a steady hand.
