Vertical Grip vs Handstop

[haymons22]

Is your rail KeyMod or MLok? Pic's too dark to tell.

The one on it currently is keymod. I don't really like it though. I had to modify it to make my bcm qd sling stud work for some reason. I like the look and feel of the diamondhead handguard but it's the only one I have even held. I have a friend that uses them and likes them. I was thinking about switching to mlok solely because all the Magpul stuff works with it.
