The 400e Gen 2 Metal is powered by an included 11.1V Lithium Polymer (LiPo) battery and USB Balanced Charger, eliminating the need to purchase them separately. With the ambidextrous AR-15 style selector switch, you can easily swap between full-auto, semi-auto, or safe modes. The battery is connected to a high RPM motor and gearbox, designed to withstand extreme force and extended firing sessions. Unlike many airguns, the 400e performs great in all types of weather, with virtually no performance decline in temperatures between 32F (0C) and 90F (32C).

Our upgraded feeding system is engineered for optimal performance when using our recommended ammunition. Using low-quality or non-recommended ammo will likely result in jams, and while the new system helps prevent gearbox damage, improper ammo use can still cause operational issues. To ensure your airgun operates smoothly and avoids potential damage, always stick to our recommended BBs.
