The Daniel Defense MFR (Modular Float Rail) is a CNC Machined Modular Free Float Handguard. It is specifically designed to adequately cover a low profile gas block on a carbine or mid-length gas system barrel. The MFR has been engineered to provide each shooter with the ultimate in modular adaptability. Should the shooter desire, the tube can be run slick with an unitterupted top rail that runs the length of the tube. In addition, the installation of Modular Picatinny Rails is accomplished with little effort. This allows you to have rails anywhere you need them and nowhere you dont. The slim profile feature of the MFR keeps the shooters support hand close to the bore which aids in firearm manipulation, and the design and construction allows for the attachment of Picatinny Rail Sections at standard 90 degree or offset angles.

    "This RIS is one of the best looking on the market, in my opinion. You get a great look and it is totally modular. I prefer it to any keymod you can get. As far as fitment, I have the 12 inch rail with a 20 inch SPR barrel on my Tippmann M4, and it looks great!

    Looks Amazing
    Totally Modular
    Great Finish with Trademarks
    Comes With 3 Sets of Rails
    Comes With Barrel Nut


    Buy it, you won't regret it. Completes any M4 build.

    The rail came with a barrel nut, which I wasn't expecting, because I had bought one already for an additional 20 dollars. The barrel nuts look the same, but I haven't trial fitted the one I bought separately, so I am not positive. Do your homework before dishing out the additional money.

    "great addition to my kwa m16! its quick and easy to install (took 5mins to put on) looks and feels great. this comes with 3 additional quick attache small rails for mounting customization which were sturdy and easy to put on. there is no instructions but its pretty easy to figure out the only con i had was there was a slight wobble even after tighting everything down but i just made a spacer for the front and its rock solid now (or adding an optic between tho bridge to two top rails could help too).

    overall i highly recomend this and was very impressed with the quality and functionality of this product and will definatley be buying more DD acessories in the future.

    "One of the best rail systems on the market

    Extremely light
    Fantastic finish with trademarks that have stayed on for over a year without a scratch
    Rock solid on many guns (currently mounted on a G&G Combat Machine receiver) no wobble and very little up, down, left or right deviation on the top rail alignment
    Very easy to install
    Fantastic design
    Slim, sleek and very "operator"
    Almost too modular! Who needs 45 degree mounts right in front of the reciever!? I don't care, it's awesome.

    Too cool looking, makes the rest of the M4 look bland in comparison
    I've heard of fitment issues on some guns, but I suggest you do some independent research
