Not exactly a new product, but for those who prefer the M320A1 from Tokyo Marui as their 40mm launcher, here is Timerzanov Airsoft going over one... "Hello everyone! Today I'm reviewing a grenade launcher, and not just any grenade launcher. It's the one and only grenade launcher from Tokyo Marui! The gas-operated HK M320A1. It's a grenade launcher that fires only 18 pellets per shot, but it has the unique feature of storing the gas inside the body of the replica, making it more reliable and less fragile than conventional systems. So, sit back and enjoy!
Tokyo Marui offers us a replica of the M320A1, a gas-operated grenade launcher that can be used on its own or mounted on an assault rifle. 18 pellets are fired simultaneously, traveling in a curved trajectory like the real thing, and spreading over an area of 2 square meters at a distance of 20 meters.
The grenade contains only 18 pellets, and the firing mechanism and gas reservoir are stored inside the body of the M320A1. This allows 18 pellets to be fired at a constant gas pressure, allowing the pellets to "hit the intended target" with a stable trajectory. It also eliminates the need for regular maintenance on 40mm grenades while making them more reliable to use. The replica is made of high-quality aluminum and polymer.
