I put the Specter Gear M-14 / M1A CQB Sling on my SOCOM16 and it has worked exactly as advertised. Easy to operate as both a single and double-point sling. I made a wide black mark on the outside surface of the sling fabric (inside the plastic buckles) for quick reference on my optimal two-point sling setting. Same for a one-point setup, only with a narrower marking. This allows me to quickly reference where my buckles need to be for each kind of sling application (obviousy in lighted settings, before rolling out). The sling will work just fine with the multi-fit nylon cheekpiece and EOTech OPMOD Holosight, also sold here. There is plenty of fabric available to fit over my rattle as well.
