Barra 400E Electric Airgun BB Rifle – Black

In stock! Usually ships within 24 hours.

It's time to spend your time actually shooting rather than fumbling with CO2 cartridges. The 400e is the first and only production full auto .177 BB gun powered completely by electricity. One battery charge gets you over 1000 shots. Featuring patent pending technology, the 400e can maintain velocities ranging between 380 and 410 fps. The consistent velocity and engineering of the rifle allow for high levels of accuracy for a BB gun. With rates of fire between 500-600 RPM (depending on battery C rating), it's fast enough to be fun, but slow enough to engage all your targets before needing to reload. With the included 50 round magazine, this gets you over 5 seconds on full-auto before needing a mag change. That's over 4x longer shooting than comparable fully automatic CO2 rifles.

OPERATION The Barra 400E Electric airgun is powered by a widely available Lithium Polymer (LiPo) battery commonly used in high end airsoft guns or RC cars. With the ambidextrous AR-15 style selector switch, easily swap between full-auto, semi-auto, or safe modes. The battery is connected to a high RPM motor and gearbox. We made the 400e gearbox 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). 

MATERIALS The Barra 400E Electric airgun is built like a real rifle with a full CNC aluminum receiver and handguard. Includes M-LOK® compatible accessory slots on the handguard for modular flexibility. The polymer 6 position adjustable butt stock with sloping cheek weld balances support and user comfort. 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 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 sold separately.
