Flux Defense Raider X – P320 / M17 Chassis, Flat Dark Earth (FDE) (161-00006)

The Raider X is Flux Defense's premium personal defense weapon chassis for the SIG Sauer® P320, M17, and M18 family — not a firearm, and no firearm is included. Flux describes it as stronger, lighter, and faster than the prior Raider, with more than a dozen updates drawn from special-operations feedback and high round-count use. This listing is the Flat Dark Earth (FDE) right-hand brace Raider X only. Flux part number 161-00006, UPC 850080943700.

What the Chassis Does

Flux builds the Raider X as the option between a handgun and a rifle: handgun-level speed and concealability with carbine-level capacity and stability when a full-size rifle is too much to keep with you. Published use cases include home defense, personal protection, executive protection, close quarters, vehicles, bag carry, and similar tight-space work. Collapsed dimensions Flux publishes for the Raider X platform are 11 × 1.7 × 6 inches; chassis weight is 18 oz.

Key Improvements on the Raider X

• Overtravel stop so magazines cannot be over-inserted.
• Reinforced frame with an upgraded single-gate mold — fewer knit-line weak points.
• Molded-in insert for the ejection spring bolt.
• Stronger mag catch spring and upgraded fencing around the dual mag release.
• Increased rail-lock spring force.
• Redesigned grip top for better access to mag release and safety; improved grip texture; matte finish to cut glare.
• Smoother magwells for faster reloads.
• Front frame reshaped to accept extended rails for increased length of pull.
• Enlarged suppressor cutout for shorter barrels, comps, or cans.
• Added slot on the bottom Picatinny rail; optic rail adjusted and slotted; slide channel under the optic rail raised for better clearance with adjustable iron sights.

Compatibility

Compatible with SIG M17/M18 and P320 in 9mm, .40 S&W, and .357 SIG. Flux states it is not compatible with P320 XTEN, .45 ACP variants, suppressor-height iron sights, or 15-round magazines. M17/M18 manual safeties must be removed and replaced with an OEM pin. To use P320 carry, compact, or subcompact slides, Flux requires a comp, threaded barrel, or suppressor — failure to do so may cause injury. The brace version is neither designed nor intended to be shouldered.

Not a firearm. Chassis only — no fire control group, slide, holster, sling, light, or optic included.
