    "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.

    "Great rail to start off with. Incredibly light compared to other ris rails that I've acquired in the past. The installation is very easy and you can probably get it up and running on your reciever in less than 10 minutes. The only problem i had was that the threading on the barrel nut did not match up to that of the G&P reciever. This isn't really a problem with the rail, but for g&p users be warned that you need a different barrel nut to put this on or a reciever with the same threading as the rail.
