Flux Defense Raider 365 Long Folding Arm Features The Flux Defense Raider 365 Long Folding Arm with SBR Endplate is purpose-built for owners converting their Raider 365 system from a pistol brace configuration into a registered short barreled rifle setup. The long arm length provides an extended reach compared to the short arm variant giving shooters a different length of pull option for their build. The included SBR endplate secures the arm to the receiver forming the foundation for the final stock configuration. This component is designed to integrate directly with the existing Flux Defense Raider 365 folding mechanism. Note that the chassis itself is not included with this folding arm so it is intended for Raider 365 owners who already have the base system in place. The compact packaging makes this an easy addition to an existing parts inventory for builders assembling or upgrading their SBR. Flux Defense products are known for their folding brace and stock systems among AR pistol and SBR builders. For those finishing out a Raider 365 based SBR conversion the Flux Defense Raider 365 Long Folding Arm with SBR Endplate is available for sale at GrabAGun.
