According to Bill Geissele, he said that Keymod is not as structurally as sound as MLOK. Now, I don't know enough about material sciences to prove/disprove this (... haven't gotten that far in engineering classes yet) ... but Bill's a mechanical engineer, so I'll say his word is good.

Is Keymod that popular of a mounting option? Doesn't really seem like; at least not to me.
