In this Field Test Shooting Video I test out the BARRA 400e Full Auto AEG 4.5mm BB Rifle to test out the velocity along with the accuracy and also get an idea on what the rate of fire is in Full Auto mode as on the box it claims 550 rounds per minute using what I would assume is a 7.4 volt battery. I wanted to test the BARRA 400e using an 11.1 volt battery but mine died on me. I will more than likely make a short video where I test out the 11.1 volt battery to see how this effects the rate of fire. If you want more information on specifications and details for the BARRA 400e then check my Table Table Video for it here.
Starting with testing out the Velocity for the BARRA 400e Full Auto AEG 4.5mm BB Rifle I shoot 6 rounds through my Chronograph to average out the fps and I was able to average 385 fps which is fairly close to the claimed 410 fps. Temperature does not effect an AEG as no CO2 is being used. Battery voltage also does not effect velocity as long as there is enough voltage to make the AEG motor pull the spring all the way back. Only trigger delay and rounds per minute are effected by battery voltage.
Moving on to my accuracy findings, I loaded up a full 50 round magazine and first unloaded 10 rounds fairly quickly into my paper target setup 30 feet down range shooting from a seated shooting position with the BARRA 400e resting on a sand bag up front. I was impressed to get close to a 1 inch 10 round grouping that placed just a little to the left and down from the bullseye right out of the box. I could easily center the sights as they are fully adjustable. I then switched the BARRA 400e Full Auto AEG 4.5mm BB Rifle to full auto and shot the remaining 40 or so rounds into the same paper target and even though the grouping opened up a little bit, it was not by much so accuracy in semi and full auto is very good with the BARRA 400e.
I have to say the rate of fire on the BARRA 400e Full Auto AEG 4.5mm BB Rifle using a 7.4 volt battery is rather slow even compared to other Airsoft AEG Full Auto Airguns but I still yet have to test it out using a brand new 11.1 volt Lithium battery so I do expect the rate of fire to improve a noticeable amount. Stay posted for that update video. Even with the slower rate of fire from the BARRA 400e this gun is awesome, it is really accurate and the velocity stays super consistent since CO2 cool down is not a factor. The mostly all metal construction and overall quality is very good and the fact that this is really the first commercial AEG 4.5mm Steel BB Rifle makes that alone a great reason to pick one up.
