FLUX Defense Launches Redux Glock Chassis at $349.99 and Sells Out First Run

FLUX Defense has launched the Redux, a two-piece brace and spare-magazine chassis for Gen 4 and Gen 5 Glock pistols, at $349.99 on its product page, which the company posted on October 30, 2026. By November 10 the page listed the first run as sold out with a waitlist, and FLUX quotes a one-to-three-week lead time on orders because of volume.

The Redux is a spring-loaded brace or stock attachment that pins to a factory Glock frame, paired with the Railmag, a spare-magazine carrier that mounts on the pistol’s accessory rail. FLUX lists it as compatible with nine Gen 4 and Gen 5 models: the 19X, 17, 17L, 45, 47, 34, 35, 22 and 31. Gun Digest, which covered the launch on November 9, lists the G46 and leaves out the 45 and 31, so FLUX’s own list governs here.

Against the original Glock FLUX brace, the company claims upgraded materials, improved ergonomics, a deeper and more secure interface with the pistol and a smoother magazine release on the Railmag. The headline change is an aluminum shroud for the magazine carrier that clears ported and compensated pistols, carries ambidextrous thumb ledges and comes off for suppressor use. Injection-molded polymer parts carry the structure, the magazine release uses FLUX’s patented button, and the housing leaves clearance for common pistol suppressors.

“Redux is about going back to the original idea with all that we have learned,” FLUX told Gun Digest. “We looked at every interface, every material, and every interaction with the platform and asked how we could make it better.” The company says it kept the two-piece layout, with the magazine carrier and the brace working on their own or together, to give buyers configuration options in states that restrict integrated systems.

Every Redux ships with the pistol brace. An SBR Stock Kit for the Redux, sold separately under the Redux accessories listing at $69.99 to $79.99, replaces the brace with a stock for a short-barreled rifle (SBR) build. The product page states that the Redux is not a firearm and includes no firearm or accessories.

The Redux sits below the rest of the FLUX personal defense weapon (PDW) line on the company’s site, where the Raider P365 Ultralight SBR lists at $409.99, the Raider X P320 at $419.99 and the Raider 365 Aluminum at $599.99. Gun Digest puts the original Glock chassis at eight years old.

FLUX lists the Redux under SKU 161-00043 and was taking waitlist sign-ups on the product page as of November 10, 2026, with no restock date posted.
