So I'm not sure how I didn't notice this before, but, if I simply retract the charging handle all the way back and then get try to get my cheekweld, there is a large degree of interference between the CH and my cheek.
Therefore, there is no adjustable-cheek stock that will work with my current mechanics, since if my cheek is on it, it will interfere with the charging handle.
RAT stock it is for now.
