Basically you lark's foot it around the krab, trapping the sling in the process. It's better than just slipping a smaller o-ring or rubber band down the sling until it's snug to the krab IMHO because it can't slip back up and come loose. That description probably doesn't help to understand how you get it in to that configuration, though. Try this:
- put one end of sling through o-ring
- clip krab through end of sling poking through o-ring
- slip finger through one side of the o-ring and pull it around the krab
- thread the free end of the sling through the end of the o-ring that you've pulled round the krab
- pull the sling tight, being a little careful as the bar tacks pull through the o-ring
- wiggle the sling around a bit and tug on it a few times to make sure everything is seated tidily and pointing the right way
- the o-ring should now be snug but not too tight on both the krab and the sling, and not going anywhere.
That makes it sound a long-winded process but it actually takes just a few seconds when you've got it sussed.
Have a look at any Wild Country quickdraw in a shop and you should be able to see how they use an o-ring in this way. You can try out the fitting technique using a rubber band before you decide shell out on o-rings.
