Mine doesn't, but I'd be willing to bet DM6 added it... I know that a lot of people do that on duckslides to remove/lessen side-to-side wiggle/slop in the slide. I've considering doing so on my original, but the little bit (and I mean little bit) of slop that it does have isn't noticeable enough... and is probably necessary to prevent unnecessary friction, so I haven't.
I say, if it's preventing additional ano rubbing (which is bound to happen w/ any pump) and isn't causing any additional pump stiffness/friction, keep it on!
