Ok, I'm going to admit I don't know anything about slings.  Single point, 2 point, three point, yada, yada, yada.  I'm going crazy trying to figure it all out.  Can some of you post nice clear pictures of examples of the major sling styles and how they are used?

The single point CQB MOUT sling is what I prefer on my M4gery.

A two point is just a standard sling, similar to what is used on a hunting rifle. They attach to the weapon at two points, front and rear.

Nice pics and links. Can't believe there isn't a FAQ or a tack on something similiar.
