otherwise, I'm old school cotton web gi sling on my field rifles (not limited to ar's). I should try one of those fancy leather ones sometime
Are you talking about a "sling" = carrying strap, or are you talking about a "sling" = shooting device that can also carry the rifle?
I'm not being pedantic, because the difference can be really significant in how one equips themselves.
SHOOTING slings for AR's start at a Leather 1907 and end up at a cuff-and-clip tactical design from somebody like Tactical Intervention.
Carrying straps start at a length of paracord.
Do you want 3 point? 2 point? Ching setup? Am I speaking Greek?
