You should be able to do that with a scout mount that puts the red dot ahead of the receiver. Check out M14.ca or Brownells (I think the one they sell is called the Ultimak). Springfield also sells a scout mount but I don't know who sells it. With some of those mounts, the sights can co-witness with the red dot, meaning that you're still good to go if the battery dies or you don't want to use the red dot in bright light conditions.
The cheapest mount was the UTG but I understand that it's no longer in production and getting harder to find. And while it allows the use of open sights with the red dot removed, the irons will probably be out of action when the red dot or scope is mounted, as it doesn't have as low of a profile as the others. In any case there should be no problem using stripper clips with any of the mounts mentioned. With our current mag restrictions that's probably more practical than changing mags if there's nothing obstructing the top of the receiver.
