Features

Upgrade your FLUX setup with the FLUX Defense Raider 365 Long Side-Folding SBR Arm with Endplate, designed for users building a compact, legally registered short-barreled rifle configuration. The extended arm provides a longer length of pull than the short-arm option, while the side-folding design helps preserve the Raider 365’s compact profile for transport and storage. Built specifically for the FLUX Defense Raider 365, the spring-loaded arm deploys at the press of a button for fast, one-handed extension. This package includes the long SBR stock arm and endplate, providing the key components needed to configure a compatible Raider 365 chassis with a shoulder stock.
