SIG Sauer has announced the official expansion of the MCX series of rifles with the new MCX-SPEAR chambered in 277 SIG FURY.

The company says: “The MCX-SPEAR was developed with direct input from U.S. warfighters to provide more power, distance and accuracy to replace the current M4 rifle platform. The MCX-SPEAR is now the most innovative and advanced AR platform in the world.”

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.

Here is what Ron Cohen, the president and CEO of SIG Sauer had to say about the new MCX-SPEAR:

“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.”
