Trigger Pull: The trigger pull on the BARRA 400e AEG Full Auto BB Rifle like other AEG Rifles is not mechanical per say as it is essentially electrical driven so basically it is an on off switch that is closest in feel to a single action only trigger since it is light and short. You will notice a slight delay between pressing the trigger and the actual round being fired since the trigger activates a motor which first pulls the air spring back, once the spring is fully drawn back it releases and compresses the air which then propelled the 4.5mm steel BB. The higher voltage battery you use will shorten the delay as the motor will spin faster and pull back the spring quicker allowing for less noticeable delay and also a higher rate of full auto fire.

Accuracy: Starting with testing out the Velocity for the BARRA 400e Full Auto AEG 4.5mm BB Rifle we shoot 6 rounds through our Chronograph to average out the fps and we were 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, we 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. We were 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. We could easily center the sights as they are fully adjustable. We 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.

Build Quality: The BARRA 400e AEG Full Auto BB Rifle is almost all metal in design with an actual CNC machined aluminum hand guard and reciever! It feels very solid when holding it and it's fit and finishes are really good. The only plastic we noticed on this AEG styled BB Rifle are the rear stock, pistol grip, and pop-up sights, everything else as far as we can tell are made out of metals.

Realism: The BARRA 400e AEG Full Auto BB Rifle is based on the AR platform in terms of its overall design and looks like a sub variant for sure. It is missing the default forward assist but in all the Airgun versions of AR typo rifles the forward assist is just for show since there is nothing to assist with an Airgun. Most mechanical parts work as you would expect like the charging handle, magazine release, sectors switch, dust cover and of course the trigger.

Pros:

• No CO2 required so cost to shoot is less.
• Very consistent velocity as there is no cool down effect from CO2 cooling the gun.
• Have the option to shoot in semi or full auto modes.
• Almost all metal construction, very solid feeling gun.
• Lots of rail option for mounting accessories (Picatinny on the top and M-LOK on sides and bottom).
• Flip up sights use a dual mode, when not flipped up you have finer optic lower profile sights, when up there is a post in the front and peep in the back.
• 6 position adjustable rear stock.
• Nice high capacity 50 round magazine, will need more mags for sure since you get 1000 shots per battery charge.
• Comes with a speed loader too.
• Lots of working parts including the charging handle, dust cover, magazine release, selector switch.
• Selector switch is ambidextrous.

Cons:

• No blowback operation as with some other Full Auto BB Rifle like the Crosman AR Series.
• Does not come with a battery or charger, will need ones that fit and use a Deans connectors.
• No red dot included with this version but the iron sights are well thought out.

Comments: The BARRA 400e AEG Full Auto BB Rifle is something new to the Airgun industry and we always like it when a company doesn’t just make their own version of something we already have in the market and basically just put their branding and licensing on all the same guns. BARRA has made what we believe to be the first AEG 4.5mm Steel BB rifle at least one that has come to market and I always wondered why nobody has tried this before? Well here it is and now we get to see how well an AEG performs with 4.5mm Steel BB’s! Maybe this will start a new market of AEG type 4.5mm Steel BB Guns? I say if it works, well then go for it.
