    "I wanted to switch my WE M4 to a mk18 mode 1. Firstly the design is great and light weight which is great.
    The unit comes with everything you want to install. But the 2 bottom barrel nut screws dont screw all the way in, so there is no threads all the way through the hole. Whats holding the the rail is the other 4 screws that are on top and sides.
    Also when you install the rail if you have the stock outer barrel there will be a massive wobble. The only way to stop this is the find a screw to screw the barrel to the gas block. Thats if you have one extra (gas block) and apparently the only kit that sells it is the angrygun outer barrel kit. There was word by using O ring to stop the wobble but that does not do it.
    Just thought I mention it..
    Overall I am happy!

    "Got it for my Krytac Alpha casue I've always loved the look of the MK18, and Krytac internals are just bar none. Comes with everything you need to mount and the instructions are good and clear. It's heavy tho, like it adds a few good pounds to the gun, I like it that way, however it may be a draw back for some.

    "I really enjoy this MK18 rail. Very well made and sturdy. I have little to no rail wobble. I can confirm that this DOES FIT on a WE GBB M4 as I currently have the rail mounted onto it. The only issue that should be address is to get a decently sized oring for the outer barrel to prevent it from wobbling. After that, the rail and the outer barrel remain solid.


    Good rail.
    Can fit on WE GBB M4


    Solid Rail
    Fits on most M4 platforms (GBB/AEG)
    Good quality


    Takes long to disassemble because of the amount of screws you have to remove.
