I just installed a KAC quick detachable sling adapter on my collapsible stock Bushy. I am using the CQB Solutions HST sling, & it has worked very well for me. All the other slings I tried got in the way of the main lamp on the SureFire, or kept hanging up on the lamp module. I don't have a digital camera right now, & I couldn't find a picture of this setup, but I'll bet Wes Grant at MSTN can post one for you.
It's certainly not the cheapest way to go (the GG&G single point adapter is a LOT cheaper), but I like being able to remove the whole sling without having to rethread everything through that tight buckle.
Edited to Add: I'm afflicted with lefthandedness too, & it works really well. The KAC adapter is ambidextrous, so all you have to do is move the QD swivel to the opposite side if you need to shoot weakhand. Of course, the HST makes weakside transitions a snap anyway....
