    Great build quality
    DD trademarks
    Easy to install
    Relatively lightweight
    All the rails you will ever need

    Heavier than a drop-in rail system

    All in all, it's a great cosmetic and practical upgrade. The quality is excellent, and the drawbacks are far outweighed by the benefits.

    Fits great on my KWA VM4A1, so I can guarantee compatibility for that platform.

    "I ordered this RIS to rebuild the USSOCOM M4A1 Block II.
    This RIS is very well made and easy to build and attach to the upper reciever.
    It's my second Madbull RIS and I love both of them.
    You can easily attach things to it and it's very durable.

    If you are thinking about buying one do it, you won't regret it!

    "This is well made and looks great. Only complaint is that you have to buy a G&P spec barrel nut separately and it is longer than the one that comes with it and is just too long by about 2mm so it is a bit tough to get the RIS to seat back against the ring that secures it without either modifying the nut or the corners of the RIS that touch it.

    This problem will not exist for non-G&P threaded guns as the included Nut is shorter.
