Description

The Barra 400e Polymer Full Auto BB Rifle is budget friendly brother to the 400e Gen 2. By replacing the upper, lower, handguard, and faux suppressor with polymer materials, Barra is able to offer a lighter and more affordable option to the original 400e Gen 2 without sacrificing performance.

This BB rifle receives all of its power from a Lithium Polymer (LiPo) battery. It reaches velocities up to 430 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 Polymer 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 Polymer 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 Polymer Full Auto BB Rifle from Pyramyd AIR today.

Split the gen1 and gen 2 barrels by taken apart the center pin and switching them. I now get over 500 fps from new one and 375 out of short one.

I can honestly say I am impressed with the quality of this pellet gun, the look and feel is really good, not to mention light weight, found the accuracy to be really good, nice design for selecting lock, single and full auto. I laughed when researching this gun, seeing others shooting in full auto seemed fun and entertaining, honestly it really is! I would agree others about the sight on this gun as the green viewer with large sight is a little distracting not to mention covers the object you are firing at. I didnt find the loader to be smoothest of quality but it does what it’s suppose to do. If wasn’t for these two things, I would have given 5 stars.

Am I the only the only person to the BEST use of this gun? Sure it's: - fun to plink with in either single or fully auto mode. - nice to not take the time/effort to change out CO2 cartridges. - good looking, well made, reasonably priced. But here's why I bought it. Outfit it with an under barrel M-lok green laser/strobe and keep it under the bed next to my Glock. If someone breaks into my home at night I can use the 400e on full-auto to distract them with a barrage of BBs to the face while I assess the true threat. If they keep coming I've got the Glock. If they turn and run, I haven't killed anyone, just ruined their day. Makes perfect sense to me. The ultimate 'non-lethal' weapon for home defense use.

I have shot about 3000 rounds out of this and just love it. The battery last a long time I easily get over 1300 shots per charge. It comes with a 100 round mag which if you're using a full auto with just 25 or 50 rounds per load it just doesn’t deliver the same smile factor as you get from a 100 round mag. IMHO 25-50 rounds in full auto is for kids under 5 yo. 100 rounds mags give bigger smiles. Barra doesn’t give much instruction as to how to keep battery charged. The battery has some limitation and caveats that’s allow me to fire so many rounds. I learned about these type of batteries after I got it and I use a volt meter to tend its charge. If you charge to early or too late your round count may drop. I think 3.7 v is the key and you must multitude it by three because there are 3 cells in it. So that means your max charge should be over about 11.1 v. Then you can’t let the charge drop below 3.0x3 =9v. Now if you let this battery drop to low it won’t ever charge back to a capacity of 1300-1500 round shot. This maybe why Barra is limiting shot count to 1000. My numbers maybe skewed as i in try to remember this all as I’m 3000 miles from my gun and notes but I remember you need to read up on that little battery. I wouldn’t store the battery in the gun for long also. This way when I plug it back into gun and if I left at 600rounds shot then I got about 700 left. But if I leave battery in for a couple weeks it would fall off to1000 and maybe less. Not sure. Barra should have added more instructions for battery. From what I can tell with some of these air gun manufacturing instructions is they usually are designed in USA but instructions are not written very good English. Therefore many of these air gun instructions get a stare from me like my dog makes at TV once she hears opera music, head cocked and eyes glassed over. But with all that said everyone who has shot it at my home always wants to shot it more from 8yo to 80yo. Trend to your battery for max shot count.
