Saw this attachment on a picture at Blue Force Gear. Look at the 5th picture in the series below the main picture. There is a rail with a built in attachment point. Any ideas who makes this - looks viable.
Thanks

I believe it's a Tango Down ESR (extended side rail) with a push button quick connect.
