Sorry to bring this back from the dead, but seeing as no one ever gave these dudes an answer...
I am running a sling from rocky mountain tactical. It is of fantastic quality, easy and rapid adjustment, many different attatchment/usage methods (single point, two point, etc).
Very reasonably priced with free shipping (last time I checked), good customer service also.
All you will need is a 1.25" sling loop that mounts to a standard sling swivel for the front. The sling comes with a buckle that will attatch to the slot on the bottom of the stock.
I can post some pictures if you want.
