Included with my sight was an item referred to as an "Extension Tube".

It is designed to thread onto the front tube of the UltraDot.

Is this a sunshade for use when shooting outdoors in very bright light?

It's wall thickness is really very thin. If installed, are you able to clamp a ring onto this tube without crushing it?

How do you folks use this thing?

I use them just to keep debris like flying powder and oil off the front lense.

I use one on my 45 because I feel the slight narrowing of the field of view trains me to come back on target better in rapid fire. I have clamped them with rings before and they didn't crush.

The tubes are quite solid. I really like them for those rare occasions where you have an uncovered firing point. It keeps both the sun and the rain off the lens.

All the above plus this

Clamping a scope ring to the extension tube is a REAL bad idea.

Kimber, Why you say that?
Been doing 2 rings on front for years now on 22. No problems at all. Won't do it on 45 though
