Brand new Tailcap O-Ring for the C G M P and Z series SureFire Flashlights. This is a replacement O-Ring that fits all of the lights listed above and more. The M series lights come with two tailcap O-Rings, but almost all SureFire lights have space for the second O-Ring, all that you need to do is add it. (note that this does not always work well with the G2 and G2z, but works GREAT with all of the other lights listed above. If you have any questions or concerns, just ask.)
O-Rings for SureFire® Flashlights
These are high-quality Nitril o-rings for SureFire® flashlights. They are neither made by nor endorsed by SureFire LLC, but they are the same quality as the o-rings that come on genuine SureFire® flashlights.
