Jeffe nailed it, they are for 7/8" carry slings and allow a low carry for bushveld use....I cannot imagine an instance where a sling is necessary for African hunting or any other kind of hunting IMO...

I used a shooting sling some, early on, but I have not used a sling for shooting for many years and I have never missed them. on a rare ocassion I will use one for carrying a rifle, very rare ocassion come to think of it, in fact I can't recall the last time I used one....

I think it was Saeed or Walter last year in Tanzania, who called my attention to the fact that my rifle had a barrel band swivel and no rear swivel in the stock.... I had been shooting that gun for 10 years...That bothered me so I installed a swivel in it when this post came up, now it is fixed....
