A tactical sling is the fundamental connection between your body and the rifle, and the Crosstac Tactical Ambi Sling improves that connection. An AR-15 sling like this sling gives you the ability to do fast conversions from single point to 2-point. The special "limited bungee" locks out at about 6 inches of extension, enough to transition from strong shoulder to weak shoulder, but short enough to get sling support when shooting 2-point.
Dual D-rings allow you to choose your own release method in single point: full bailout or rifle only. Thesofter webbing means there's no chaffing, as it conforms to your body.
