Great and easy to use once installed - Magpul Industries ASAP Ambidextrous Sling Attachment Point

This is a great addition to any rifle. If you like to run a one point sling set up, then this is what you need. I would recommend this for all build, actually, it will be going on all my rifles. It is important to note, however, that you will need the AR wrench tool to loosen the castle nut etc.
Pros: Robust, Easy to Use, Adaptable
Cons: Installation
