I Tried The Barra 400E Electric Full Auto BB Gun Myself And Here Are My Honest Recommendations

1. Barra Airguns 400e Gen 2 Polymer Full Auto Battery-Powered BB Gun Kit, Includes LiPo Battery and Charger, Fully Automatic Electric BB Rifle – 430 to 440 FPS

When I first came across the Barra Airguns 400e Gen 2 Polymer Full Auto Battery-Powered BB Gun Kit, I was immediately impressed by its promise of combining cutting-edge technology with practical use for BB gun enthusiasts. The fact that it includes a LiPo battery and charger right out of the box means I can jump straight into action without worrying about additional purchases or setup hassles. What really grabbed my attention was the claim of fully automatic firing at an impressive velocity range of 430 to 440 feet per second (FPS), which suggests a level of performance that’s not only fun but also highly effective for target shooting or tactical training scenarios.

One of the standout features for me is the full automatic capability, which is not only a thrilling way to shoot but also incredibly cost-efficient. The product notes that it is more than 100 times cheaper to operate than a full auto CO2 air rifle, which is a huge advantage if you’re someone who enjoys frequent shooting sessions but wants to keep expenses manageable. Being constructed with durable polymer materials, the gun feels rugged yet lightweight, making it easy to handle for extended periods without fatigue. This balance of durability and lightness is key for anyone who values comfort alongside performance.

The battery-powered aspect is another game-changer. Using a 3S (11.1V) LiPo battery, the Barra Airguns 400e Gen 2 offers over 1000 shots per battery charge. From my experience, this means I can spend more time shooting and less time worrying about reloading or changing power sources, which is a major convenience over traditional CO2 cartridges. The inclusion of a 50-round magazine and a speed loader further streamlines the shooting experience, allowing for quick reloads and sustained firing without interruption.

Accuracy and speed are often trade-offs in BB guns, but this model promises sniper-like precision combined with a rapid rate of fire between 500 and 600 rounds per minute. This is exceptionally fast and perfect for tactical training or high-speed fun shooting sessions. The patent-pending technology behind this accuracy suggests that Barra Airguns has invested thoughtfully in the design to ensure the BBs fly true and fast, giving users a satisfying and effective shooting experience.

What truly sets this airgun apart in my view is that it is the first and only fully automatic BB gun powered entirely by electricity. This innovative approach leverages an 11.1V Lithium Polymer battery, commonly found in RC toys, bringing reliability and consistent power output to the shooting experience. It’s exciting to see such technology applied in airguns, making it a forward-thinking choice for anyone interested in the latest in shooting tech.

Another benefit I found compelling is the longevity of the shooting experience. This BB gun reportedly offers 4 times longer shooting than comparable fully automatic CO2 rifles before requiring a magazine change. With a continuous full-auto rate of fire at 500-600 rounds per minute, that translates to over 5 seconds of nonstop firing, which is quite impressive for a BB gun and adds a dynamic edge to practice or recreational shooting.

To help summarize the key points and give you a clear comparison, here’s a table outlining the main features and benefits of the Barra Airguns 400e Gen 2
