This "From the Vault" video from Brownells Gun Tech features Keith Ford and Joel Colander of Rock Island Auction Co. exploring the unique Manville Gas Gun. Designed by Charles Manville in 1935, this tear gas dispensing firearm was intended for law enforcement and military use but failed to gain traction during the Great Depression. Despite its obscurity, the Manville Gas Gun achieved a cult following after appearing in the film "The Dogs of War" as the "XM-18 Grenade Launcher." A scaled-up version was also famously used in "Terminator 2." The video highlights its distinctive rotating cylinder, which allowed for multiple shots, a significant innovation for tear gas launchers of its era. Keith Ford explains the surprisingly simple mechanics of this historical oddity.
