New Hampshire-based Sig Sauer this week announced it has completed the delivery of the company's Next Generation Squad Weapons system to the U.S. Army.

As previously reported by, Sig is one of three contractors who in 2019 got the nod from the Pentagon to continue with the NGSW program. The sweeping initiative aims to replace the Army's 5.56mm NATO small arms – such as the M4 Carbine and M249 Squad Automatic Weapon. Sig’s program consists of an in-house-designed lightweight high-performance 6.8mm (.277-caliber) hybrid ammunition, NGSW-AR lightweight machine guns, NGSW-R rifles, and suppressors.

Notably, the other two competitors vying for the NGSW contract are formed by consortiums, whereas Sig is going alone – with components of their system produced at their Arkansas and New Hampshire facilities.

"This historic moment is the culmination of an incredible collaboration between the U.S. Army and Sig," said Ron Cohen, the company's president and CEO. "We commend Army leadership for having the vision to undertake this monumental procurement process and for remaining vigilant in their mission to bring a modern, transformational weapon system to the battlefield."

Standard features include a fully collapsible and folding stock, rear and side charging handle, free-floating reinforced M-LOK handguard, fully ambidextrous controls, and a quick-detach Sig Next Generation suppressor.

Cohen said this week that, throughout the program, the company was given "unprecedented access" to the soldiers and Marines who will ultimately field these weapons.  

"These soldier touchpoint events have led to rapid advancements over the current weapons systems and resulted in our delivery of the most innovative Next Generation Squad Weapons system to the U.S. Army," he said. 

According to the Army Acquisition Support Center, down-selection and a decision on the winner of the NGSW program is set to take place this fiscal year, with the first unit equipped with production guns in 2022.
