Features

Complete your registered SBR configuration with the FLUX Defense 1.5" SBR Stock for the Raider X P320. Designed as a factory-fit upgrade for the FLUX Raider X chassis, this stock extends 1.5 inches beyond the flush-fit model to provide a longer length of pull and a more comfortable shoulder position. The extended design gives shooters additional space without sacrificing the Raider X platform’s compact profile. Built for compatible P320-based Raider X configurations, this stock is a practical option for range use, training, or replacing an existing stock component on a properly registered short-barreled rifle.
