The FLUX Defense Raider chassis adds a dual-rod, spring-loaded, quick-deploy brace actuated by a right-side release, offering fast deployment and a compact profile. The rear chassis block integrates a backup iron sight and a 1913/Picatinny rail segment, while the dustcover provides an accessory rail. The chassis shows molded identifiers including RAIDER, FLUX, a patent URL, and NOT A VFG, with the rear block labeled BACKUP IRONS.
The 5.5 inch barrel is threaded 1/2x28 and comes with a knurled thread protector installed. A thread-on compensator is included in the box for the buyer to install if desired. This setup supports straightforward use with common 9mm muzzle devices.
This P320 configuration is striker-fired with a polymer/composite foundation and an earth-tone frame finish. Capacity is 21+1 with the extended magazines, and the included 17-round magazine provides a standard-length option. The steel magazines are marked Made in Italy with witness holes for quick round-count checks.
Mounting options are flexible thanks to the top 1913 segment on the rear chassis block and the dustcover accessory rail. Illumination is handled by the installed VTIGER weapon light. The package also includes two Wilson Combat P320 grip modules, the original SIG P320 grip module, an F10 Top Charging Handle, and a single-point bungee sling with QD swivel, enabling multiple configuration paths using the supplied components.
