Flux Defense Raider 365

If you have been looking for a compact, versatile chassis system that transforms a standard pistol into a true PDW, the Flux Defense Raider 365 is the platform that has been generating serious interest among shooters who value portability and accuracy. This 9mm system is designed around the popular SIG Sauer P365 family of handguns, giving you a stable, shouldered platform that still fits into a backpack or range bag. Whether you are a competitive shooter, a dedicated enthusiast, or someone looking to bridge the gap between a handgun and a carbine, the Raider 365 offers a unique solution that feels both familiar and refreshingly different.

Overview

The Flux Defense Raider 365 is not a firearm itself; it is a complete chassis that houses your existing P365 or P365XL slide and fire control unit. Once installed, it provides a stabilizing brace, an integrated magazine well, and a full-length top rail for optics or accessories. The result is a compact, highly controllable shooting platform that retains the concealability of a pistol while delivering the stability of a shoulder-fired system. Many shooters describe the Raider 365 as the ultimate “truck gun” or “backpack PDW” because it folds down into a surprisingly small package. The chassis uses a folding brace design and includes a quick-detach sling mount, making it easy to carry and deploy. It is built from reinforced polymer and uses steel inserts in high-wear areas, so it holds up to regular use without adding unnecessary weight.

Features & Specs

When you get your hands on a Flux Defense Raider 365, the first thing you notice is how solid the lock-up feels. The chassis uses a patented locking system that secures the firearm in place, and the integrated brace deploys with a simple flick. Every Raider 365 ships with a standard Picatinny rail section on top, allowing you to mount a red dot sight directly over the bore axis. It also includes an integrated magazine well that speeds up reloads and works with standard P365 magazines. The overall length with the brace collapsed is under 11 inches, and it weighs just over 10 ounces without the firearm installed.

• Compatible with SIG Sauer P365, P365X, and P365XL slides and fire control units
• Folding brace with multiple length-of-pull adjustments
• Integrated flared magazine well for faster reloads
• Full-length top Picatinny rail for optics and accessories
• Steel reinforcement inserts at critical lock-up points
• Quick-detach sling mount included
• Caliber: 9mm

Who It’s For

The Flux Defense Raider 365 is built for shooters who want the versatility of a pistol-caliber carbine without the bulk of a traditional long gun. It is an excellent choice for anyone who carries a P365 for personal defense and wants a more stable platform for range training, home defense, or vehicle carry. Competition shooters who participate in pistol-caliber carbine matches will appreciate the compact form factor and the ability to use the same magazines and ammunition as their carry pistol. It is also a popular option for those who simply enjoy trying new shooting platforms and appreciate well-engineered gear. If you already own a P365 and want to expand its capabilities without buying a completely separate firearm, the Raider 365 is a natural upgrade. It is not a toy or a novelty; it is a purpose-built tool that serves a specific role for practical shooters.

• P365 owners looking to add a PDW-style platform to their collection
• Home defense users who want a compact, accurate option for tight spaces
• Range shooters who want a stable platform for running drills with their carry gun
• Travelers who need a packable firearm option that still offers rifle-like control

Shipping & FFL

Because the Flux Defense Raider 365 is a firearm chassis and not a complete firearm, it can ship directly to your door without an FFL transfer in most states. However, if you choose to purchase a version that includes a complete slide and fire control unit, or if you are bundling it with a firearm, that specific item must be shipped to a licensed Federal Firearms License (FFL) dealer for transfer. Please check your local and state laws before ordering. We ship all FFL items to your chosen dealer, and you will need to complete a standard Form 4473 and background check upon pickup. If you have any questions about what applies to your order, our team is happy to help clarify. You can always reach out before completing your purchase to ensure a smooth transaction.

• Chassis-only orders ship directly to your home address (no FFL needed in most states)
• Complete firearm bundles must ship to a licensed FFL dealer
• All customers must comply with federal, state, and local laws
• Contact us with any questions before ordering
