Nice and simple - Samson KM-EVO-1237 Evolution Keymod AR-15 Aluminum 12.37in Rail

1st AR build and still in the process of completing the build but the Samson product seems legit. Solid construction and light weight. Very open and "see through" which I like in order to keep my build to a minimum. The product came with everything needed and the whole package really only contains two parts. Not a whole lot of bolts so I imagine install will be simple yet solid. Rail does have T Marks but they seem to be etched in and a goldish to yellow color which I like versus bright white. Everything lines up well with the top receiver.
