I'd like to use a rail like this:

Do you maybe now if this rail will fit on my KJW m4?
I contacted my "home" Softairshop if they can do it, a thing i didn't find on the arnies thread, what size has the hole to be and what screw to you have to get in there, what kind of set-screw?
If i know the size of the hole and what kind of screw i have to use i may just contact my uncle he has got one of those stationary drillers and I can just use that one, as it looks really simple (how the mod works)
/Edit: On that note, how do you mount rails like the madbull one or the one i posted? to you just twist it on the thread where the delta ring sits on, or do you clip it under the delta ring like the magpull handguards ... i will do the mod tomorrow but i just can't find a screw that would fit there :S And a mate told me you have to do something to fix the screw in there as it will move when you just screw it in ... any suggestions?
