Flux Defense Raider X Chop Top El Camino FDE P320 Chassis

The Raider X Chop Top “El Camino” is a compact chassis system designed for the SIG Sauer P320, M17, and M18 family of pistols. By removing the non-reciprocating optic mount from the standard Raider X configuration, the Chop Top fits into a smaller space while allowing an optic to remain mounted directly to the slide.

The streamlined design also provides a lower optic height over bore and makes it easier to move a compatible slide and FCU between a pistol and chassis configuration. The reinforced Raider X frame incorporates an overtravel stop, upgraded molding, a molded-in ejection spring bolt insert, stronger magazine catch spring, and increased rail-lock spring force for improved durability and reliability.

Updated ergonomics include a redesigned grip top, reshaped front frame, smoother magwells, improved grip texture, and a matte finish designed to reduce glare. An enlarged suppressor cutout accommodates shorter barrels, compensators, or suppressors, while an additional slot on the bottom Picatinny rail provides more accessory options.
