I've done a bit of research, but having trouble deciding what sling to buy for my new Colt. I like the look of the single point systems, but I've never carried a rifle like that. I've only carried an M-16A2 with the regular 2-point sling at the end of the buttstock and the clip under the front sight. What are the advantages of each type of set-up and what slings/mounts do you recommend? Mostly a plinker, with minimal to no "tactical" action. Maybe some 3-gun in the future, but it appears that most 3-gun stages don't really require a sling of any type.
