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.

*Battery and charger are sold separately.

*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.

Fun shooting gun not real accurate

I enjoy shooting the 400e it's great fun. The 400e is well engineered and built too shoot and last for a long time. I may be a little critical but the accuracy of my gun is a bit disappointing. Tried sighting in at 70" from a bench rest and sand bags and got a 6' group, tried again at 50" and got a 4' group. This was done at an indoor range with no wind.

Good times with the 400E! A fun and satisfying shooting experience.

I fired 1000 rounds through my 400E this weekend and I had a blast doing so. I like Barra's honest and up front approach to marketing this gun: it's a really fun plinking gun with full auto capabilities (it is not meant for pest control). This gun is purpose built to put a smile on your face while target shooting/plinking. With the gun being electric, I was worried that the sound would annoy me but I got used to it. It is relatively quiet and does not draw attention from neighbors. My CO2 air guns and even my spring-loaded Beeman rifle are louder than the 400E. I do think air guns sound better when fired but I can load multiple magazines and hundreds of BB's and never have to change out CO2. So, that is worth the sacrifice of a more “mechanical” sounding shot. I can live with the electric noise in lieu of spending $$$ on CO2 and the time it takes to change it out.

The 400E was pretty accurate with the provided sites right out of the box. My targets were all placed between 10 – 30 yards away. I shot both cans and targets and I prefer setting up cans and blasting them in full auto. ☺ I will be upgrading to a scope for better accuracy but it’s still a solid aiming gun.

I recommend purchasing at least two batteries and lots of BB’s.

Verdict: Lots of fun. Worth the price of admission specifically because of the $$$ saved on CO2. Recommend!

Pros:
Lots of fun
Shoots straight / accurate
Full auto capability (buy lots of BB’s!)
Nice weight / balance
Adjustable stock

Cons:
Provided BB speed loader: if it breaks, you can’t load the magazine. I tried to order an extra but the site says they are out of stock.

Tons of fun

I’ve only run a few clips through it, maybe 10 total but it’s a lot of fun. Puts a smile on everyone face who shot it. Loading the clips with the plunger takes some getting used to. I used steel bb’s. Maybe copper would load easier. I suggest buying the battery, charger and extra clip, or two. Like anything that empties clips quickly, keeping a supply of full clips is the hard part.
