AR10's do like to be run a bit more wet than an AR15 does. With the mags, I've found that when you modify them for the Armalite conversion kit, you need to clip off several wraps of the spring, otherwise you can't get all 20 rounds into the mag, and the spring pressure is so great that the mag has too much friction to feed, with the tendancy for the follower to nosedive. Also, I've noticed that you need to bend the top few wraps of the spring backwards, sometimes a great deal, to force the front of the follower up. I did find that my followers wouldn't slide freely inside the mag, many were would rub along the front ribs, and needed a bit of work with the dremel tool to operate freely.
