Barra Battery-Powered .177 BB Gun Only

Sold & shipped by Pyramyd AIR

Barra 400E Price


Caliber.177 (4.5mm)
Max Velocity410 fps
Muzzle Energy2 ft/lbs

The Barra 400e 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 410 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 50-round magazine in just over five seconds with exciting full-auto shots.

The Barra 400e 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 Full Auto BB Rifle from Pyramyd AIR today.

3 star and here's why. 1. I love the weapon. 2. I don't love the fact that a) batteries are not included, b) a charger is not included, c) BB's (even a small bottle) are not included. I can't give you a better rating till I actually fire it. Once I received my firearm, I should have been able to put it together, take it outside and USE IT - SAME DAY not a month later waiting on this piece and that piece to wend its way across the PACIFIC OCEAN to get to me. Just my thoughts! Vr/ Phil

  • Dave from USA asked:

    I am considering the Barra 400E. My question is at Barras website it states copper plated bbs should not be used. Elsware I have read that zinc platted bbs should not be used. Why the prohibition on these ammo types, what happens if they are used? Why so much conflicting information. It seems Barra makes copper plated bbs.

    • Rum Runner from USA asked:

      So.. save $10 by ordering it separately? 399.99 +19.99+19.99= 439.99 or 449.99 combo? Come guys?

      • John from USA asked:

        $449.99 is a lot of cash for a new to the market gun, that you don't even show being shot in a marketing video.

        • John from USA answered:
