Bought this to replace the previously two toned handguard on my G&G GC16 (full metal) raider. Unfortunately when I opened the package I discovered that it is made from an injection moulded plastic, such as those found on the entry level CM16 raiders, not metal as I had hoped. I will be returning the handguard in favour of finding a metal replacement.
Despite this mix up, my delivery arrived the day after i placed my order, which was impressive. The rail system also came with all the mounting hardware required (barrel nut and 4 bolts), and the construction appears to be of standard G&G good quality.
In summary, while it isn't what I wanted, I can imagine it being perfect for anyone who wants a lightweight rail or a cheap replacement for that on their combat machine.
