BLACKHAWK Magazine Pouches can be attached to your duty belt or dress belt. Pouches feature a unique built-in tension spring that keeps your magazines secured until they are needed. Belt clip is removable, fits up to 1.75" wide belt. All of the CQC magazine pouches are made from a carbon-fiber composite material. If Carbon Fiber is listed in the description, it means that the outside surface has a carbon fiber appearance (the fibers are visible). Pouches that are listed as Black only are the same composite material but have a solid matte non-reflective finish.
