I've run ADM and LaRue. Both great mounts, but my personal favorite is Bobro simply because I like the on/off detachment mechanism better.

For stocks you can look at the Magpul PRS. It has both an adjustable comb and LOP. Only problem is they run about $200 new. However if you check out the classifieds on some of the AR specific forums you can usually find a used one in new/excellent condition for around $150 - $175 shipped.
