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

Features that I likedAll metal construction. Consistent velocity and fpe across shot strings. Accuracy is as advertised. Comfortable platform. Very quiet. Multi-shot (50 round advertised magazine). Built-in M-Lock slots. Weaver rail for scope mount. LIPO Battery power. Automatic mode.Suggestions for the manufacturerIf I could, I would have allowed some other way to fill the magazine besides the auto-loader, which is cumbersome and I was not actually able to fill the magazine to 50 rounds. I managed 42 with multiple tries.My report on operation and testing:Data was gathered using FX Radar Crony. I could not believe my eyes when I ran the numbers showing up on my FX crony. I ran a 5 shot string and a 42 shot string and the fps averages were virtually identical!! I then ran a 5 shot string fpe and a 27 shot fpe and the numbers there were also too close with differences that were negligible. Using Umarex Steel 5.29 gr BBs and shooting a 5 shot string, High velocity was 398 fps. Low was 389 fps. Average velocity was 394 fps with an SD of 3.03 fps. My 42 shot string results were virtually identical but SD was 2.08 fps. Energy delivered over a 27 shot string was an average of 2.51 fpe with an SD of 0.0314!!!The consistency in velocity and energy were virtually flat across each shot string. No fall off with shots fired. This outstanding BB rifle exceeded the original 380 to 410 mfg spec with a consistent average of 394 fps flat out. Max velocity was 398 fps. The rifle is a little heavy, since it is all metal but it shot 1 inch groups at 28 feet consistently!!! In Auto mode, it was pretty close in accuracy. I installed a Rex compact 1.5x5.1x24 red dot scope. The magazine is advertised as 50 BB capacity but realistically max I could get into the magazine was 42 BBs. BBs were Umarex 5.29 gr Steel. The batteries were Zeee 2200 mhr 3S LIPO and they performed flawlessly. This is a 5 Star performer. It is quiet, and is the most accurate BB gun I own. I would rate this rifle 5 Star all the way.ADDITIONAL THINGS YOU SHOULD KNOW:Several; weeks after my purchase of the 400e I still think it is a great BB rifle. With a number of shooting sessions behind me I have learned a few things that I thought are worthwhile writing about and that others should know.First and foremost, I was totally unaware of what a LiPo battery was; only that it delivers a lot of power for the money and is used extensively by Airsoft and other hobbyist in their rifles, cars, drones, etc. Here are a few things that I have learned about the care and feeding of LiPo batteries that I did not know beforehand. (1) For safe and long-life health of a LiPo battery, you should make a point of checking the charge level, individual balance between each of the cells of your battery, and each cells internal resistance. Checking your battery requires a much more functional balace charger than the basic one (although the basic balance charger will do the job, it will not tell you how good or bad your batter is... only that the cells are charged). A good LiPo Balance Charger will give you more details in most cases. Alternatively, a LiPo Battery Checker will do the same but it will not charge your battery.(2) LiPo batteries should be charged in a fireproof safety bag. Although you do not need one, if the unexpected happens, you will wish you had used one when charging your battery.(3) Storing a LiPo battery fully charged on a shelf is OK if it is in a safe storage bag, but storing a 'fully charged' LiPo battery for extended periods of time will decrease it's overall life span. If you have several or many LiPo batteries for your 400e to use either through rotation or as 'on-the-shelf backups, you will need to store these batteries at a lower voltage by discharging them to the recommended storage level. A good LiPo Battery Checker can generally do this discharge safely for you.(4) when I purchased my 400e I knew none of the above! I do not regret my purchase. I love the rifle and took the necessary steps to add a better charger, testing equipment and safe charging/storage bags to insure that I could continue to use my 400e safely. Knowing that taking some extra time before and after shooting sessions to check my battery's health will insure longer battery life.While I am no LiPo battery expert, I think I would have made a more informed purchase had I researched a little more thoroughly beforehand. Hopefully, the above will help other potential buyers to understand the 'extra' care involved in using a LiPo battery. There are lots of excellent videos on YouTube on the care and use of LiPo batteries to get you up to speed on how to make the most of your purchase. Amazon and other suppliers do carry the additional items to check and maintain your LiPo batteries. Hope this helps. Hopefully, others might join in with their experiences and advice for novice potential buyers.

A most excellent choice for a fun, cool bb gunVery accurate with just the iron sights, Have not put my red dot on it yet may not need to !I saw a lot of reviews first and the quality being reported was great for the rifle.Also noted the fact people were saying the speed loader sucked and was cheesy...They were quite right.I am glad the loader is somewhat clear to see what is going on but I thought the people might have been trying to ham fist them in maybe, maybe not.I agree it is crappola but that did not make my decision figured I could work around it and with that for a while perhaps with a bit of wear it will loosen a bit. "however" I like this beautiful machine so much.No muzzle lift , no recoil ........why hit the bullseye when you can just carve it out.much love , much enjoyment , BARRA....Well done Amazon, thanks for the fast shipping.At 65 years of age That is how long I have waited for this. No Co2 ,no leaks full autoWTF LOLOLOLOLOLOLOLOL also as a veteran very familiar with the M16A1 rifle i used , this was a automatic fit right out of the box.. Yes you better send some towels with it so we can wipe the smiles off...maybeCheers all

Gun shoots great but magazine and loading stinks. Loader doesn't work well and BB's end up on the floor. Better loader and higher capacity mags are a must!!!! Get that updated and you have a great BB shooter!!!!!

Battery powered, no more filling up co2 or purchasing co2. A ton of affordable fun!

Motor stripped gears and gun is completely useless after less than 2 charges and maybe 2000 rounds. I contacted the company about the issue and they never responded. Do yourself a favor and buy from a more reputable company than barra. It did shoot good, until it completely took a crap. Now it's just an expensive paper weight.. barra, F U!

This rifle is a ton of fun to shoot as it is to add accessories to it. I already added a strap and red dot sight with attached laser. Although it does not include the battery, neither do airsoft guns. Anyone who has used airsoft will know exactly how to enjoy this rifle. RC guys probably already have the batteries laying around somewhere.The loader is a bit fidgety but if you know how to manipulate the movement, you can load it pretty easy. Its not a simple press, over and over. You have to lean and maneuver it before pressing the loader in small batches of BBs. Easy to learn once you get the hang of it. However, a loader re-design is in order.I don't recommend it for varmint control. Perhaps mice, but not much more than that. Its good for target practice or plinking. Its quite accurate at about 30 yards. In my experience, without a scope at that distance is more than sufficient to get some accurate shots in semi mode. Your mileage may vary in rock & roll mode, but its fun over accuracy.If you don't have the cash to spend on this rifle, save up and try again. Its more fun than you expect. Even if you don't shoot often, this rifle looks like it means business, even when not in use.

This is blast to shoot. Accurate to about 35 to 40 feet. Full auto is really fun to shoot. Glad they included a BB loader with the unit, which makes it easy to load mags. One should have a target box to catch all the BB's so they don't ruin your lawn mower. Should have a very large box of BB's available as this thing eats them up. Dang is it fun to shoot.

So far great and I mean great. Right out of the box nothing to do but charge battery and shoot. Boy can you go thru bbɓbbbs in hurry. But that is what I wanted. I am sure I will settle down. Now I have to hide it from my son 32 .if gets ahold of it. We'll you know. You can't even tell it's not metal. Great job done
