Mounting Surefire Scout

Please tell me I’m not going nuts…

I’m attempting to mount a Surefire Scout to a Knights rail. When I unscrew the Surefire mount all the way, it’s still not wide enough to clear the width of the rail. Looks like i need a star-shaped allen key to loosen the other side of the mount.

This doesn’t seem right to me at all. Can anyone shed some light on the subject?

problem solved…

Just called Surefire and sending it back for warranty repair… received a defective unit.
