I've looked at the same idea for a kimber hunter
there are qd inserts that glue in but I like the ones with a screw post on the bottom to put into a backing inside the butt stock
not sure how to get backing into the fore end
Noveske makes nice flush mount QD sling mounts for hollow stock applications, last ones I bought were from Tier One Armoury.

Thanks for including the RDSC link. I ordered the flush mounts from this Canadian site. Its a little pricey though at 40CAD each cup...
