The sling is intended for AR, no doubt. So far its been on a Ruger 77mkII carbine, (synthetic, 20'' tube) a Mini-30, and of all things, a Mannlichier stocked Mossberg .243. All three rifles have sling shackles, which simplifed things a bit. Again, cable ties are your friend. But a rifle with swivel studs could be fitted with naked sling swivels, and you could rig from there.
BTW, the rifle is forward around my neck, 'cause the treestand is on my back!
