I've got a handful of lowers I need to replace the sling mount on. Problem is that I have this: I had nylon webbed leaders with plastic buckes hanging on the rifles. I also had two slings. Well...I moved and somewhere, somehow the slings lost. I'm wanting to ditch the mount and get something like this: (Well, that is what I think I want.) Anything special I should go for? Why suggest an alternative to my preferrence? I mean...what's the reasoning behind it? I need to outfit multiple lowers, so cost is somewhat of a concern as far as the mounts go (or, then again, maybe not because I can buy one or two at a time). Of course, I'll need a sling (or three) to use with the new mounts. So -- in essence -- what sling? What mount? Why? Go.
