4UAD Smart Airsoft got a bunch of the new Acetech Hive and Spawner Package, which is the 40mm gas shell that can be loaded up quickly putting the airsoft grenadier back in the game quicker than others. This is a highly efficient system that reloads in just one second. It can fire 80 BBs in a single shot and is compatible with all 40mm grenade launchers. The cartridge tube’s status can be quickly identified, enhancing its usability.
