FLUX Defense Updates Its Glock PDW Chassis With Redux

FLUX Defense has released an updated version of its Glock chassis system, the FLUX Redux, aimed at making the brace-equipped PDW setup more durable and easier to run.

Snapshot

FLUX Defense built its reputation on turning Glock pistols into compact PDWs, and the Redux is the company's first major rework of that chassis since the original launched eight years ago. The update focuses on materials, ergonomics, and how securely the chassis mates to the host pistol, while keeping the same modular two-piece design.

Key points

• Fit and feel: FLUX says the Redux uses upgraded materials, a tighter interface with the pistol, and a smoother magazine release compared to the original chassis.
• New shroud system: An aluminum shroud now accommodates ported or compensated pistols and adds ambidextrous thumb ledges, or it can be removed entirely for suppressor use.
• Brace to stock: Every Redux ships with a pistol brace, and a separately sold SBR Stock Kit allows conversion to a stock for owners who go the NFA route.
• Core function unchanged: The chassis retains its spring-loaded, quickly deployable brace/stock and a Railmag forend built to hold a spare magazine.
• Price and fit: MSRP is $349.99, and it's compatible with Gen 4 and Gen 5 Glock models including the G17, G17L, G19X, G22, G34, G35, G46, and G47.

Quick take

FLUX Defense describes the Redux as a return to its original concept after examining every interface and material on the platform. For Glock owners who already liked the idea of a brace-equipped PDW chassis, this looks like a refinement rather than a reinvention, with the suppressor-friendly shroud and SBR stock option standing out as the most practical additions.
