NEWINGTON, N.H., (January 13, 2022) – SIG SAUER is proud to announce the official expansion of the MCX series of rifles with the new MCX-SPEAR chambered in 277 SIG FURY. 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.
“This is a rare opportunity for passionate consumers to own a piece of history,” began Ron Cohen, President & CEO, SIG SAUER, Inc. “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.”
The MCX-SPEAR is an adaptable multi-caliber rifle (277 SIG FURY, 6.5 Creedmoor, 7.62 NATO, with barrel change) featuring rear and side non-reciprocating charging handles, 6-position folding stock, ambidextrous fire control, bolt-catch, and mag release, 2-stage match trigger, 2-position adjustable gas piston, a lightened free-float M-LOK™ handguard, a full-length picatinny rail, and ships with (2) 20-round magazines.
“The revolutionary SIG FURY ammunition is the most technically advanced leap in smalls arms ammunition in over 150 years, this turns your intermediate rifle platform into magnum performance without the added weight or length while still using 20-round magazines,” added Cohen.
The 277 SIG FURY ammunition is the commercial variant of the 6.8 x 51 hybrid military round available in the hybrid case technology submitted to the U.S. Army NGSW program. Also available is a 277 SIG FURY FMJ traditional cartridge round.
“The final component of this special-edition offering includes the SLX Suppressor. The design of the SLX suppressor is optimized to dramatically reduce harmful toxic backflow and features our patented QD attach/detach system making installation of the suppressor a game-changing level of ease,” said Cohen.
The SIG SAUER SLX Series of suppressors are designed to drastically reduce toxic fume inhalation by the end-user and sound reduction and are available commercially for 5.56, 7.62 NATO, and SIG FURY 277 calibers. The SLX suppressors feature a monolithic core construction in Inconel, an internal multi-flow path to exhaust gases at a higher rate resulting in lower toxic fume inhalation, a sound reducing baffle design, a flash reducing end cap, and are available with either the new Clutch-LOK QD mounting system for easy install and removal that offers an intuitive tactile locking ring with infinite radial locking positions, or direct thread.
