I have a practically new PentagonLight X3. This is the hard anodized model that has a green color. It comes with the standard tailcap and a push on/push off clicky cap ($29 accessory). This light has been on for approximately 60 seconds total (yes, really). Has the box and lanyard as it came from the factory.
I also have a Daniel Defense offset mount. Looks new. Comes with packaging.
Here it is mounted up:
Light is $115 by itself. Mount is $50 by itself.
Buy both for $155 shipped. **BOTH ITEMS SOLD**
