This entry details the Airtronic modernized China Lake 40mm grenade launcher, a prototype developed for US Marine Corps trials following the Battle of Fallujah. It highlights the design modifications, including Picatinny rails and an AR-15 buffer tube interface, intended to integrate modern optics and stocks. The project faced challenges due to legal disputes and the potential danger of adapting the design for high-pressure 40mm ammunition, ultimately leading the USMC to adopt the Milkor M32A1 instead. The analysis draws from the expertise of firearms historian Ian McCollum.
