Built on the modular P320 FCU architecture, this configuration drops the fire control unit into a Flux Defense Raider chassis. The brace is a dual-rod, spring-assisted, lever-deployed design with an endcap marked "PISTOL BRACE." Chassis markings include "FLUX," "RAIDER," "NP17," "NOT A VFG," and "AMERICAN MADE."
The chassis adds a non-reciprocating top rail and a front 1913 accessory rail. A forward spare-magazine well provides a dual-magwell layout. The included magazines are SIG Sauer steel units made in Italy, and the system supports a 21+1 capacity with the extended magazines.
The slide is a Norsso aftermarket P320 slide with weight-reducing window cuts and aggressive forward serrations. It houses a 4.7-inch barrel with a "9mm x 19" caliber marking on the hood. The action is striker-fired, semi-automatic.
The P320 platform combines a stainless steel receiver module with a polymer frame. This full-size configuration is rail-equipped and set up with the chassis-mounted top rail for direct accessory mounting. The Raider brace deploys via lever and telescopes on dual rods.
