Alright, I need a little help/educating. It's time for me to order a sling for my AR. I'm pretty set on an MS3 because it seems to be a solid and versatile sling. And since I have the CTR stock, I was thinking to go ahead and get the QD version. Since this is my first AR, I don't yet have much opinion on how/where I'd prefer to mount a sling. Is there any reason why I should consider the standard MS3 instead? I really do like the idea of the QD, as long as it's as secure as people say.
