How are you securing it?

I'm using the "teeter totter" looking tooth thing on the top rear portion of the rail that has the hex-screw. Just above where the gas tube goes into the upper receiver. The tooth hooks into the inside of the barrel nut. This is a RAS I. I'm not sure how different a RAS II mounts.
over all, you're right the SF is more secure since you have the 2 screws pushing the bottom half into the barrel nut. Versus the RAS where the bottom 1/4 of the KAC can come on and off w/ the slip-ring. However, the top 3 rails are all one unit and mounted securely. I use the rails as a flashlight and vertical grip platform. If I were mounting optics I don't think I would use any of the 2 piece options and would use a one piece FF one.
The first time I installed my surefire, the bottom half wasn't seated all the way. I tightened it up, mounted my front grip and the first time I put any real pressure on the rail, it popped back and into place and started rattling... had to re-tighten the screws. No big deal. lesson learned & personal preference established.
edit: Went and found the KAC manual - the RAS I and RAS II are the same, just a longer "Top Rear Cross Screw" on the RAS II because of that hump connecting the flay top and the rail.
