Flux Defense Raider 365 Ultralight PDW Chassis for SIG P365 XL - Black

The Flux Defense Raider 365 Ultralight is a polymer PDW chassis that converts your SIG Sauer P365 XL pistol into a stabilized, shoulder-fired personal-defense platform. At just 8.7 oz, it is the lightest chassis in the Flux lineup, adding rifle-style stability to your everyday-carry pistol without meaningful bulk.

Extended, the chassis measures 18.5" overall with a 13.5" length of pull; folded, it collapses to a palm-friendly 9.75" carry profile that disappears into a bag. The unit stands 4" tall and roughly 1.25" to 1.375" wide depending on orientation, so it tracks like a familiar handgun while shouldering like a carbine.

Built around a molded textured polymer grip module in a black finish, the Ultralight mates with SIG P365 17-, 21-, and 25-round magazines for serious firepower. 12 to 15-round magazines are not supported, and the chassis is engineered for P365 XL slides; standard 3.1" P365 slides do not fit.

From a discreet truck gun to a stowable home-defense package or a stabilized training platform, the Flux Raider 365 Ultralight brings compact-PDW handling to one of the most popular concealed-carry pistols on the market.
