Description
The Barra 400e Gen2 is a full auto BB rifle that delivers intense action and limitless enjoyment for plinking and fun target practice. A first in the market, it is a select-fire BB gun that receives all of its power from a Lithium Polymer (LiPo) battery and reaches velocities up to 440 FPS and a cyclic rate of approximately 550 rounds per minute (RPM).
The heart of this BB gun is the Lithium Polymer battery that provides consistent power and operation compared to the CO2 cartridges found in competing airguns, meaning it performs well over long shooting sessions and in a variety of temperatures. With the ambidextrous select-fire switch, this BB gun easily shifts from semi-auto to full-auto (and safe mode), allowing shooters to either get semi-auto shots for careful placement, or to empty the 50-round magazine in just over five seconds with exciting full-auto shots.
The Barra 400e Gen 2 Full Auto includes flip up front and rear sights that can be removed and repositioned. In addition, the rear peep sight is adjustable for windage, and the BB gun has a long Picatinny optics rail for adding a scope. To provide further options, the CNC-machined aluminum handguard has M-LOK slots on the bottom and both sides for accessories such as bipods, flashlights, and lasers.
This BB gun has an AR-style textured pistol grip and a custom 6-position adjustable butt stock for variable length of pull. For convenience, the butt stock includes a quick-disconnect sling mount, and the package comes with both a balanced battery charger and a speed loader to make filling the magazine simple.
To get a truly unique and exhilarating AEG BB gun shooting experience, buy the Barra 400e Gen 2 Full Auto BB Rifle from Pyramyd AIR today.

Very very well built, right out of the box the sights were dead on. I would suggest some type of red dot scope, it helps while on full auto.
Awesome job BARRA on the design and overall performance on the 400 e Gen 2
This gun is awesome. I’ve not had this much fun with a gun since I was a kid, I am 62 years old now. It could use more power, but perfect for walking around the farm and shooting nuts out if trees and plinking around. Now to the reason for 4 stars…the rear site is useless. I cannot get it to adjust for wind age as the screw heads are plastic and when I tried the heads just ripped apart and became useless. I ordered another rear site made from metal like the rest of the gun is and now I have a robust little gun to play with. I thought the entire functioning or adjustable part of the gun would be metal since I ordered the “metal” version of the gun. Don’t get me wrong, I would buy this gun again every time, just know you need to change the sights to make it the perfect little plinking gun.
Awesome fun . Heavy duty feels like a real AR-15 best fun ever.
The price is good, the quality is excellent, and it looks like the real thing.
I bought this airgun last September and im so happy about it. My first time to have a full auto airgun without the worry of paying a lot for Co2. And I dont have to worry about what is the weather. I use it in any weather.
I have had my rifle about a week and usually fire a hundred rounds a day. The 400e fires fast and accurate. It is very well engineered and all parts fit perfectly. Auto mode is just awesome.
I personally like it, it’s good for this kids to target shoot in the back yard
Bought this last week. Had a blast shooting it. It is pretty solid gun and worked great until I tried using different bbs. Seemed to jam frequently.
