Features

The FLUX Defense Raider 365 Ultralight is a lightweight PDW-style chassis system built for the SIG Sauer P365 platform, delivering enhanced control, rapid deployment capability, and compact portability in an ultra-streamlined package. Constructed from advanced polymer composite materials with reinforced steel components, the Raider 365 Ultralight is engineered for shooters who want the stability and performance advantages of a personal defense weapon without the weight of a traditional PCC. The sleek black finish provides a clean tactical appearance while maintaining the durability needed for defensive, range, and training applications. Designed around compatible P365 XL, TACOPS, and FUSE slide assemblies, the Raider 365 Ultralight features FLUX Defense’s patented Speedload System, integrated spare magazine storage, and a spring-loaded brace system for fast deployment and improved handling. The chassis supports 17, 21, and 25-round P365 magazines while maintaining a highly compact footprint measuring just 9.75 inches collapsed and weighing only 8.7 ounces. Suppressor-ready clearance, included holster compatibility, and modular accessory support make this an ideal platform for concealed carry setups, modern PDW builds, and compact defensive use.
