Cro recently got a surefire helmet light, and when he went to set it up on his ACH, he found the screw driver on his issue Gerber multi-tool (a fine tool and one of my favorites) was too large for the attachment screws.
The Tube came to the rescue, and one of the driver tips in the expansion kit was the perfect size for the mission.
You don't find much better praise for a tool than that of front line soldiers who are tough on their gear.
