The original 3-point Ching Sling is traditionally mounted on the Scout Rifle. (it'll work on any rifle...just add a swivel stud in front of the magazine)
This is the Ching Sling that Jeff Cooper writes about as designed by Eric Ching. Available in 1" or 1.25" widths and in three leather colors, 3 hardware choices. Brass, nickel, or Duracoat/Cerakoted black.
NOTE: 1" only for the Steyr Scout if you have a new Steyr, it has the swivels in the accessory bag. (see my other slings for the Steyr slings complete with swivels if you do not have them)
NOTE: You will need to drill a 1/8" or 9/64" hole in your stock to mount this sling. Instructional photos are on this page and enclosed with each sling (video soon!).
The Ching Sling is also available from Steyr and Brownells
