This is a helpful addition to my tactical flashlight.

I mounted this item on a Klarus XT2CR.
It does a great job of providing a secure purchase on the flashlight. I have found that flashlights can become slick from having wet or gloved hands. This ring diminishes the wet/gloved hands problem. It makes the light easier to hold securely.

Very easy to install. Just remove the tail cap, and slide the ring onto the body of the flashlight. Replace the tail cap. Note: The ring has a domed side and a flat side. The flat side must be oriented towards the tail cap.

My only complaint, is that the ring freely rotates around the body of the flashlight. I wish it would not rotate. In all honesty though, I don't feel this effects it's usefulness.

I will be buying another one, for my wife's XT2CR.
