    "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!

    "Hey, thank you for the first international order from you shop.
    Perfect Service and very fast Shipping. The Color is the same from the short version MK18 (short und long rail at home). Greets vom Rheinland Pfalz Germany

    Leute, kauft euch das Teil. Passt an SAEG genauso wie an GBB. Hab beides probiert. Die Rail hat ein Bronzefarbenen Farbton der perfekt zum schwarzen M4 passt.
    Vergesst aber nicht denn Zoll, da müsst ihr ca. 22€ bezahlen (20% vom Kaufpreis), und vorallem bringt eine Rechnung von Paypal mit!!! Dann geht alles problemlos. Die Rail war in weniger als 3 Wochen da.

    "WOW! this rail system is so versatile and great! i just got mine today, and to be honest, i was a little bit shocked. First to start with the one and only CON: the color is more of a brown. it doesnt even much resemble dark earth or FDE for short. other than the color, i was blown out of my chair by this product! A bit expensive, but all worth it. im not an extremely large player, I am only 5'10 150lbs, but my arms are very long, and this rail system is the most comfortable position wise, for my arm, especially with a foregrip near the front end. it looks completely amazing and i promise you wont regret this purchase! I hope this review helps

    Cons:near a brown copper color
    Pros: versatility, length, strength of material, rail space markings, real estate for accessories, removable lower half for barrel mounted grenade launchers.
