Flux Defense Raider 365 Aluminum – Black PDW Chassis (161-00012)

The Raider 365 Aluminum is Flux Defense’s personal defense weapon chassis for the SIG Sauer P365 — a chassis upgrade, not a firearm. Drop your P365 fire control unit into a duty-grade 7075 aluminum and S7 steel frame with a Type III hard-anodized finish, a spring-loaded brace, and Flux’s patented Speedload System. This listing is the Black configuration. Flux part 161-00012, UPC 850080943724.

World’s Smallest PDW Footprint

Flux built this chassis to deliver subgun-level control without carbine bulk. Collapsed it measures 9.75" × 4" × 1.375"; extended it goes to 18.5" × 4" × 1.25" at a 13.5" length of pull. Chassis weight is 12.6 oz without the firearm. You get three to four points of contact for steadier shooting, and the package stays compact enough for on-body or bag carry.

Speedload, Shroud, and Controls

• Patented Speedload System — spare magazine on the chassis with a dual-mag release for faster reloads; up to 50 rounds on the gun with optional mag extensions.
• Built-in shroud for a secure C-clamp grip and flatter follow-ups.
• Spring-loaded brace that deploys and collapses for carry or shooting.
• Uses factory P365 safety levers.
• Optional fixed red-dot mount and optional 6" barrel for more velocity.
• Suppressor clearance up to 1.55" diameter.
