Slings come in different types such as the 1 point sling and the 2 point sling which all aim to carry your airsoft gun as easy as possible.
Besides the easy carrying of your airsoft gun, you can easily swing the sling sideways to easily and quickly get access to your side arm (pistol) and to get it out of the holster. A sling is especially useful for the heavier airsoft guns because the weight of the gun gets more distributed over the shoulders.
