Operation

The 400e 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 Barra Airguns Zinc Coated Steel BBs. 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 Barra Airguns Zinc Coated Steel BBs.

Materials

The 400e Metal is built like a real rifle with a full CNC aluminum receiver and handguard. It includes M-LOK® compatible accessory slots on the handguard for modular flexibility. The polymer 6-position adjustable buttstock with sloping cheek weld balances support and user comfort. It also features a strengthened buffer tube for added durability and includes QD sling mount and slot for other straps.

Style

Designed as a modern sporting rifle with no frills and a clean frame, the 400e Metal looks great out of the box but is still highly adaptable for you to customize and make it your own.

Accessories

Includes 1x 50-round magazine, speed loader, and flip-up sights. Battery and charger are now included, so you're ready to shoot right away.

Additional Info

BATTERY REQUIREMENTS The 400e Metal includes a 3S (11.1V) LiPo battery with a 25-35C rating and Deans (T-Plug) connection. A balanced charger is also included for safe charging and battery maintenance. Using a battery that meets these standards is crucial for maintaining the performance and longevity of your rifle.

COST TO OPERATE The 400e Gen 2 Metal is extremely efficient to operate and more than *100 times cheaper per shot than a full auto CO2 rifle. A 40-count CO2 pack costs about $25 and gets approximately 2,000 shots with a full-auto CO2 BB rifle. The included LiPo battery and balanced charger provide 200,000-400,000 shots when properly maintained.

*Energy cost for battery usage was calculated based on The National Average Energy cost of 14.8 cents kWh, a 2200 mAh battery, and an 800 mA B3 charger. Energy cost for CO2 based on 60 cent cost per cylinder and 100 shots per two cylinders.

UPGRADED VELOCITY AND ACCURACY

With refined design and patent-pending technology, the 400e Gen 2 Metal delivers even higher velocities, up to 440 FPS. Coupled with a smoother feeding system, this upgraded model offers superior accuracy, making it perfect for high-speed target practice with rates of fire between 500-600 RPM.

RECHARGEABLE LiPo Battery

The 400e Gen 2 Metal comes equipped with a powerful 11.1V LiPo battery, delivering over 1,000 shots per charge. Swap between full-auto, semi-auto, and safe modes using the ambidextrous AR-15 style selector switch for uninterrupted shooting sessions. Now including a USB balanced charger, you're ready to shoot right out of the box.

LOW-COST, HIGH-EFFICIENCY SHOOTING

Operating costs of the 400e Gen 2 Metal are over 100 times cheaper per shot than comparable full-auto CO2 rifles. Thanks to its rechargeable battery, you can enjoy long-term savings and consistent performance without the hassle of CO2 cartridges.

DURABLE & ADAPTABLE BUILD

Built for extended use, the 400e Gen 2 Metal features a full CNC aluminum upper, lower, faux suppressor, and handguard. Its polymer 6-position adjustable buttstock provides customizable comfort, while the strengthened buffer tube and M-LOK® accessory compatibility offer added durability and adaptability.
