While I have no plans nor want to change the quad rail on my rifle, the M-LOK and Keymod are definitely the way to go I think for most applications. Smaller in diameter, lower profile mounting, lighter and they got to be cheaper to make than cutting out a quad rail, ya think?
I have no idea how these are made and how much they cost. Another reason is the 2 new ones are much easier on the hands. Quad rails need rail covers if you are not wearing gloves.
