  • Handle and firing mechanism assembly
    Patent number: 10830549
    Abstract: A Handle and Firing Mechanism Assembly (H&FMA) provides a robust and streamlined H&FMA for a mortar weapon system. The H&FMA is easier to assemble and eliminates jamming issues, and firing pin protrusion adjustment procedures. It also incorporates a lighter trigger squeeze in Trigger fire mode and locks the firing pin in Drop fire mode. The handle is easier and more cost effective to produce. The H&FMA can be used with, for example, a 60 mm mortar weapon system.
