Weaver Lens Caps

I ordered a set of these for the Redfield scope, and I'm pretty pleased.  They use a rubber stretchable material to hold onto the end of the scope, and the ends are clear.  This means that you can take a shot without removing the caps.  It is better to press the little buttons that pop the spring-loaded caps out of the way, but I suppose if you were hiking through the woods, and suddenly found yourself staring at a wolf 30 feet away, you could take immediate action if required.
