“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.”
