An arms manufacturer based in the city of Grand Junction agreed to pay one million dollars in compensation for the low-quality M320 grenade launchers delivered by the US Army. 

Weapons that did not meet technical standards were supplied to the arsenals from July 2016 to March 2018, RG reported.

According to the Denver Post, US Attorney for the Colorado County Jason Dunn said the company’s officials knew that the trunks were made of cheaper and less durable type of steel, but did not tell the army about this.

About low-quality grenade launchers became known thanks to engineer James Cole. He informed the management about the defective parts, but his statement was ignored. Five months later, the engineer was fired, and Cole reported the facts in November 2017 he revealed to the federal prosecutor's office. The investigation lasted about two years.

The M320 grenade launcher was officially adopted by the US army in 2009.
