I went with the MI SSK Keymod 10.5". The clearance between the hand guard and the bottom edge of the SLR Sentry 7 clamp-on screws is .007". I filed them down so I have a clearance of .011". If that isn't enough after I check to see if there is hand guard movement from using a bipod, I'll buy the set screw type. I hope that helps someone else. I'll let both companies know, as they were curious too.
