Description
The Barra 400e Gen 2 Full Auto BB Rifle is a first in the market. It is a select-fire BB gun that receives all of its power from a Lithium Polymer (LiPo) battery. It reaches velocities up to 440 FPS and a cyclic rate of approximately 550 rounds per minute (RPM) to deliver intense action and limitless enjoyment for plinking and fun target practice.
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 100-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.

I bought this fine air rifle . First time shooting it I was totally surprised at the response that it I capable of . It really a great addition to my air gun collection.

Outstanding rifle all the way around. Gen2 has made all of the big changes making this a more stable platform to have in your arsenal

What a fun pinker! Full auto is kinda cool too! Solid build, hefty and feels correct in the hands. No issues whatsoever! Recommended!

The Barra 400E is the most accurate BB gun I ever shot! Also the feel, and weight of the BB Gun is very nice! I love that you can shoot 1,000 rounds Per Battery charge, instead of replacing C02's after a 100 or so shots with most BB Gun Platforms. Excellent Product Barra! Very Impressive. AL

wow what a difference in power and accuracy ! I have a gen 1 so i can compare them side by side and yes the claimed upgrade in power is noticeable, and the accuracy is better too !

Just received in mail. Appears excellent quality. shoots strong and straight. Would recommend at this point. Looking forward to alot of shooting

When I received the weapon I was shocked at the quality ! The look and feel is exceptional and its an absolute joy to shoot. I highly recommend.

Every time I touch this BB, gun I giggle and laugh, it is really cool sixty years old, and it's my version of the red rider.I feel like a kid every time I pulled the trigger, it's awesome.

The bb rifle is well made and very accurate. I dont need to waste money on CO2 anymore.
