Like VASCAR2 said, its all about the placement of that first rib that the cartridge shoulder rests on to keep it in place. That cant be changed, and is why 7.62x39 mags dont work with 6.5G either. The follower really doesnt do much in comparison, and Im not aware of any source for 6.5G followers.
I remember way back when there were no 20 round 7.62x39 short mags and someone said 25 round ASC 6.5G work fine with 7.62x39. I bought three, none were even remotely range reliable beyond 10 rounds. Swapped in 7.62x39 followers & stronger springs and tweaked the feed lips, but only mildly better, so they went in the trash.
I run .300bo, 7.62x39, 5.45x39 & 6.5G thru ARs and the only round that runs in a mag its not designed for is 5.45x39 in GI straight 5.56 mags with a tilt follower, and thats usually only good up to 15 rounds.
