The final component of this special-edition offering is the SLX Suppressor. The design of the SLX suppressor is optimized to reduce toxic backflow and features SIG's patented QD attach/detach system. The SLX suppressors have a monolithic core construction in Inconel, internal multi-flow path to exhaust gases at a higher rate resulting in lower toxic fume inhalation, sound-reducing baffle design and flash-reducing end cap.

“This is a rare opportunity for passionate consumers to own a piece of history. This first production run MCX-SPEAR, and all of the revolutionary technology behind its development, is being offered to the commercial market in a configuration that is a near match to our NGSW-R submission. Further, this is the only rifle submission to the program that is designed and engineered in the United States by a company with the manufacturing scale and proven adherence to military-grade quality requirements—which is a tremendous source of pride for everyone at SIG Sauer.”
