Help mounting an X300U to carbine

[cosine]

I have a BCM carbine with a fixed FSB and a KMR handguard to which I'd like to mount an X300U. I'd like the setup to be ambidextrous as I shoot left-handed and my wife shoots right-handed. I'm thinking of mounting the X300U at 12:00 in front of the FSB, and putting an XT07 on the top rail behind the FSB.

How can I mount the light in front of the FSB? Or, are there any other suggestions for ambidextrous X300U light placement and activation technique on the KMR and fixed FSB I have to work with?

I would suggest one of these. I have one on a loaner carbine, and it works well.

That looks perfect, but I can't find it in stock anywhere. Any other options?

I run a SF X300U at 1:00 on my duty rifle which has a BCM KMR foreend. I use an Arisaka mount (http://arisakadefense.com/collection...y-mount-keymod) and my X300 also wears a Unity Tactical button guardy thing.

Have several of these mounts, work well for me. May have an issue if you have a middy and short arms.

I have a couple of the same thing only from GG & G. I've used them on my work rifles since we have a carbine length rails and cannot make permanent modifications.

That MI mounts looks like it will work... thanks for all the suggestions.
