Description

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 400e 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 400e 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. 

BATTERY REQUIREMENTS Using a 3S (11.1V) LiPo battery with a 25-35C rating and Deans (T-Plug) connection is required. A XT60 or XT30 male to female deans connector is acceptable as long as it is a battery that meets the standards stated above. DO NOT use a battery that is below or exceeds these standards as it may damage your motor and gearbox. Using a balanced charger is recommended to safely charge and balance your battery. Please follow the instructions for charging and use found with the battery and charger that you use.

COST TO OPERATE The 400e 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. A LiPo battery and balanced charger are about $30 and should get 200,000-400,000 shots with the 400e when the battery is 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.

Awesome Fun

I've only had my 400E for a brief moment and have nothing but fun. The packaging was perfect and the rifle has done as advertised. With no CO2 being a bonus. I highly recommend buying the Barra 400e.

No CO2

Great for target practice. Constant fps. Wish loading could be simpler. No need to keep changing cartridges. Recommend this product.

Digital Camera of Airguns

This thing is hilariously fun & highly recommended. Quality built, pretty darn accurate for a BB gun, electric, and full auto! The only danger... it is addictive. I put at least 1,500 rounds through it in my first week - still on the first battery charge with no signs of degradation. It is kind of like moving from film to a digital camera - I am probably now generating more quantity than quality. Just like my pictures.

Only constructive criticism: a) it looks so much like a real AR15, might scare the neighbors ;-) b) has a feel of quality but is heavy. Probably as heavy as a real AR15. c) speed loader can be a little finicky. Barra addressed this immediately by sending a new speed loader which helped. Thank you.

Would love to see different magazine designs in the future as though the current magazine looks just like a real AR, a lot of wasted space? And, 50 rounds is just not enough anymore now that I am addicted. Especially not on full auto.

I have a feeling these might sell out fast as word gets around.

Good gun ,Bad magazine & Speed loader

I would give the gun a 10 star rating , But the magazine needs some work, The BBs jam up in the speed loader, You shake bang the loader and then load a few more and you just got to keep repeating the shake and banging and load a few more, It works a lot better if you put a drop of BALLISTOL on the plunger in speed loader not sure if this is good on the gun?
