Sig Sauer Launches Commercial Variant Of NGSW MCX-Spear

Sig’s entry into the U.S. Army’s Next Generation Squad Weapon Program, the MCX-Spear, is now available on the commercial market.

The U.S. Army’s search for a replacement for the M4 is not over, but Sig Sauer’s entry has made it into the final stages of the Next Generation Squad Weapon Program. Sig’s rifle, the MCX-Spear, now has a semi-auto variant available on the U.S. commercial market. Sig claims that it is currently the most innovative and advanced AR variant in existence.

The MCX-Spear is not the only NGSW Program entry to receive a commercial variant with this news, as a commercial variant of the 6.8x51mm hybrid military cartridge is launching alongside it. Called 277 SIG FURY, this new cartridge will serve as the original chambering for the commercial MCX-Spear, although caliber conversions are possible as well. For those interested in the new rifle but don’t want to stockpile a brand-new cartridge, swapping the barrel on the new MCX will allow it to fire 7.62 NATO and 6.5 Creedmoor too. Sig has claimed that their new cartridge provides “magnum performance” without added weight, however, so it may be worth considering.


Sig’s new rifle will feature a 6-position adjustable folding stock, ambidextrous controls, match-grade trigger and an adjustable gas system. The MCX-Spear will also include a free-float, MLOK handguard that features a full-length Picatinny rail for mounting optics. Sig’s NGSW suppressor entry, the SLX, is available now as well.

Sig Sauer President and CEO Ron Cohen said this about the new commercial Spear variant:

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.

The commercial MCX-Spear will ship with two 20-round magazines and has an MSRP of $7,999. Each purchase will include two boxes of the new 277 SIG FURY ammunition as well.
