I have one of your scout mounts on my 13" keymod mk4 and it installed with no problems, and the rail was cerakoted. I got another mount for my black 9.5" mlok mk4 and had to do some filing on the rail to make the lower bracket fit on the rail. The bracket was to wide and to long to fit any of the offset sections on either side of the rail. Just wondering it this was normal or not.

And I just had to do the same thing again on my 13" mlok mk4 rail with its scout mount.

eblack,

The Surefire Scout Light Mount is designed for the Super Modular Rail series MK1, MK2, MK3, MK4 (MOD 0 & MOD 1) and MK5 rails. This does not include the MLOK series. Sorry for the confusion.
