Original Item. Only One Available. Federal Laboratories (often FedLabs or Federal Labs) was a US firearms manufacturer, established in Pittsburgh in the early part of the 20th century[date missing], that produced tear gas and less-lethal riot guns, including the Federal Riot Gun. The company was sold in 1994, eventually becoming part of BAE Systems, and has not operated as a separate brand since that time. Not Available for Export. 

This is an interesting tear gas CS grenade from the Vietnam War period. The grenade is very small, only measuring 4 ⅛” tall with a 1 ⅜” base diameter. The fuze is unmarked, and the grenade retains a torn up label:

No. …
