Carbine length quadrail setup. Saw this particular unit at the gunshow at a few booths. No markings, made of aluminum, rubber pads the fit the whole thing. Name brand starts with a "v". Don't remember for sure. - $30 Would prefer contact through here then I will provide a phone number if legit interest is shown.
I got a chance to meet him. I believed it was a 2 piece rail. Direct replacement so it mounts to your delta ring and end cap. So drop in all the way
