The core of this build is a Sig Sauer P320 slide and stainless steel receiver installed into the Flux Defense Raider P320 chassis. The chassis is marked RAIDER, F.L.U.X, SPEED LOAD SYSTEM, and AMERICAN MADE, reflecting the purpose-built nature of the setup.
Controls and handling are enhanced by an ambidextrous, top-mounted T-style charging handle and a dual-mag release. The Raider dual-mag system features an integrated forward spare-magazine carrier clearly labeled "NOT A VFG" with molded "BOTH MAGS" instruction, enabling quick access to a second magazine.
The slide features lightening/vent windows along with front and rear cocking serrations for confident manipulation. The 5.5 inch barrel is marked 9mm 1/2x28 and is threaded 1/2x28 with a thread protector, ready for use with compatible muzzle devices.
Multiple mounting options are available via Picatinny rail sections: a short top rear rail, short left and right fore-end rails, and a full-length underside fore-end rail. The system is configured for a stated capacity of 30+1 and includes two 30-round SIG SAUER-branded extended magazines made in Italy.
