I can't see why it wouldn't feed properly, though it may require a little finagling on magazine position.
For example, I built a 284 on an FN SPR. I had to fit the magazine release just right so the bolt *wouldn't* catch up on the magazine, but *would* catch on the case head. Obviously, with the rebated rim you have a smaller target.
Still, wasn't a big deal, it was really close before I tweaked it.
