3D Animation: How a M79 Grenade Launcher Works

Check out our Gun Apparel at: We ship worldwide. The M79 grenade launcher is a single-shot, break-open grenade launcher that fires a 40×46mm grenade, which uses the High-Low Propulsion System. The High-Low Propulsion System is a design using a smaller high-pressure chamber for storing the propellant. When the propellant is ignited, the higher pressure gases expand through ports to a larger low pressure chamber to push the projectile forward. The high-low system allows the weight of the weapon to be reduced. Different types of ammunition were produced for the M79 including explosive, anti-personnel, smoke, buckshot, flechette (pointed steel projectiles with a vaned tail) and illumination. The M79 grenade launcher resembles a break-open shotgun, having only five major parts: a receiver group, a fore-end assembly, a barrel group, a sight assembly, and a stock. The rear sight on the M79 is a folding ladder–style leaf sight. When unfolded, the leaf sight
