Product Summary

Cloud Optimized Rail. The worlds first purpose-driven hand guard that recesses your light/laser controls into your rail and seamlessly integrates your switching for truly optimal ergonomics and enhanced protection as well. Your switching has never been integral to your rail system. Until now. The days of your switches being forced to work around your hand guard are over. COR puts your light/laser activation first by recessing the switching into the rail and optimizing your ergonomics in the process.

This rail is an absolute steal. The Cloud lighting solutions are genius and this rail makes them that much better. The quality is what you would expect for a product made by BCM. I have my OWL on order and I'm stoked.

This was my first purchase from Milspec Retail. I'm always skeptical of ordering from new places but this was a smooth transaction with quick shipping. I'll be back.
