The M320A1, which can be used alone or mounted on assault rifles, is available as a gas grenade launcher in the lineup. Eighteen BB bullets fired at the same time follow a mountainous trajectory (curved trajectory) just like the real thing, and spread over 2 square meters at a distance of 20 meters.
The grenade (cartridge) contains only 18 BB rounds, and the firing mechanism and gas tank are stored inside the main body of the M320A1. As a result, 18 BB bullets can be fired with a constant gas pressure, and it is possible to "reach the target point" with a stable trajectory.
