The grey overcast Michigan sky blows for detailed photos!
The sling has four possible positions with two metal "straps" you can position.
The following pic shows it well. From the magpul.com site. The sling "straps" can be removed and put on the opposite side of the stock for left-ies (or wrong-handed people if you prefer!).
Two vertical sling positions near the rear of the stock, or two horizontal positions on the buffer tube area clser to the receiver.
And a pic of my LR308 new little brother...
