Flux Defense Raider X Chop Top “El Camino” – FDE (161-00041)

The Raider X Chop Top “El Camino” is Flux Defense’s open-top PDW chassis for the SIG Sauer P320 / M17 / M18 family — chassis only, not a firearm. Flux machines off the non-reciprocating optic mount and fits a redesigned back cap so you keep a slide-mounted optic, drop the optic height over bore, and shrink the package for jacket or bag carry. This listing is the FDE Chop Top only. Flux part 161-00041, UPC 850080943502.

Why Chop Top

• Smaller footprint — easier to conceal under a jacket or in a compact bag.
• Slide-mounted optic retained — swap the slide and FCU between pistol and chassis without fighting a chassis optic rail.
• Lower optic height over bore for faster holds up close.
• Compatible with optic-mounted slides and suppressor-height sights.

Chassis Features (Flux Factory Chop Top)

• Overtravel stop to prevent over-insertion of magazines.
• Reinforced frame with upgraded single-gate mold; molded-in insert for the ejection spring bolt.
• Stronger mag-catch spring; upgraded fencing around the dual mag release; increased rail-lock spring force.
• Redesigned grip top for mag release and safety access; smoother magwells; improved grip texture; matte finish to cut glare.
• Enlarged suppressor cutout; added slot on the bottom Picatinny rail.
• Front frame reshaped to accept extended rails for increased length of pull.

Compatibility

Compatible with SIG M17/M18 and P320 in 9mm, .40 S&W, and .357 SIG. Not compatible with P320 XTEN, .45 ACP variants, or 15-round magazines. M17/M18 manual safeties must be removed and replaced with an OEM pin. Safety may not work with all aftermarket or adjustable triggers — verify before use. For P320 carry, compact, or subcompact slides you must run a compensator, threaded barrel, or suppressor. Firearm, FCU, slide, holster, sling, lights, red dots, and pictured accessories are not included.
