Tiny print, very useful!
Boom! These! Love em. If needed, they can be modded to fit a Keymod rail with a bit of careful filing down the profile on the underside of the attachment. MLok accounts for slightly wider slots. Flat file half a millimeter off on each side and try. I have attached two of these on different Krytac builds and it worked both times, just make sure to screw it down TIGHT with Keymod nuts ok?
