This is a good quality sling with solid ERB and perfect side-mount for the M16A2. However I had been using an old Blackhawk sling that had two ERBs. The rear one detaches the entire strap like the Specter. While a second front ERB when detached allowed the sling to slide back as a loop around my body with the sling still attached to the stock mount. This was a very useful feature on missions when I had to dive to a prone position but did not want to completely detach my weapon. I recommend a two ERB style sling for anyone who actually needs it for combat.
Pros: Easy setup and quality materials, wide strap
Cons: second front ERB
