COR (Blem)




This is a cosmetically BLEMISHED product. It is fully serviceable and functional. You get a complete COR kit, as normal. However, it can have a varying degree of the following:

  • Plating inconsistencies
  • Scratches
  • Dents
  • Pitting/surface inconsistencies

This is a perfect opportunity for people who push their equipment hard and do not mind cosmetic imperfections. We do not accept returns on blemished products but these are fully warrantied as normal.

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.
