Those who have been looking for this sling, Airsoft Armoury has this for almost a month now... "The Viking Tactics Single Point Sling allows the operator to adjust the sling from a fixed length to a dynamic “bungee” action. Our cam-lock allows you to adjust the overall size of the sling, then rapidly loosen it by pulling the release. The sling features a snap-shackle for easy attachment and instant detachment of your weapon. The Single Point Sling comes with four different attachment points designed to fit standard carbines and SMGs."
