I think I just figured it out. There must be some sort of "dual" adapter available, that allows 2 slings to be connected to the single bottom stud at the front, and then each sling goes to it's own side at the rear? I think I'm even gonna get bold enough to say that, if that ISN"T the way it is, that is the way it SHOULD be!
They are set up as I posted earlier,for a tactical type front carry and more carry options.There are slings that hook to both points but you can quick release the rear, or front for more manuvarability , there are slings that also have a second loop in them for this purpose.Common more on AR type set ups.On one loop rifle can hang at side or hook front and it is over shoulder and back like a safari sling.On a side not Len sells a double shoulder sling on this sight, jsut like a regular but goes over both shoulders.The Safari sling is split front and rear and cradles the rifle
For steep climbing the side mount slings allow you to lay the rifle across you back at 45 degrees (bolt and windage knob outward) while avoiding any unwanted swing or trigger guard gouging. It works equally well for four wheeling or snowmobiling if you do not want to rack or case your weapon. Classic ak-47 technology finding its way onto precision rifles . A regular leather cobra sling on side mounts is by far my preference. P.S. I shoot my pistol in a straight line with both hands.
I haven't looked at the links yet, but it sounds like whatever one prefers IS out there. And a single regular sling WILL work. But it is the resulting loss of symetricality that is something I'd prefer to avoid.
