Holy shit. With this sling you can throw your rifle over your shoulder like a rock guitar player! See 0:25 and 0:52. Try doing that inside your house.

I have no doubt the slings are made well, but they should have just really gone over the top with this video since they already decided to include some silly ass moves.
I really doubt the "rifle throw trick" is taught in the armed forces. With that being said, operators gonna operate.
