When I bought this gun it was on sale for $99. With the fps & all the features I knew it was a steal. What really blew it out of the water was it's nice weight & the option to put a refillable Co2 tank off a paintball gun, saving you BIG $ & giving you an average of 1200 between refills using a standard 20 oz. tank. 5 stars easy. BUY IT!

We rigged ours with a remote coil and 68CI HPA tank in a belt pack, laser on the picatinny and rechargable LiFePO4 batteries. Works OK for suppressing rodents up to about 30 feet. Reloads are MUCH easier if the hopper is only fillled half way. Hopper slide door can easily open and spill BBs accidentally Batteries only last for about 200 - 300 shots per charge; so glad we're not buying new batteries everytime. Right in the middle between a toy and a real air rifle; but still kinda fun

This was the 4th bb gun I have purchased. This was the one that turned out to be just what I was looking for. Important to keep charged batteries in it. I added open sight with target (cross hair) display. That made for quick target acquisition.

Pros
Works as advertised.

Cons
none

By JohnUSAJanuary 23, 2017

This think is a blast to shoot. The auto fire modes are great, and the limit to 2, 4 or 8 rounds is more sparing on the Co2. I have other full auto guns, and I usually shoot in limited bursts anyway. The need for batteries is a bit of a drag, but not a big deal. Pretty darn accurate too.

Pros
FULL AUTO!!! large bb capacity. Accuracy.

Cons
A lot of plastic. Batteries.

The Umarex EBOS is more accurate than I expected it to be, even with the crude sights. It is LOUD, though. One would think that Umarex would include a compensator/suppressor with this gun to make it quieter, but they don't. The only EBOS compatible compensator I found at Airgun Depot costs $37.99, which is way more than I want to spend. The little sliding door on the BB reservoir is loose and will come open and dump your BBs if you aren't careful. It's a shame to have to secure it with a piece of tape. It can also be a bit of a chore to shake the BBs from the reservoir into the loading tube. To make up for the crude sights, I tried a Hawke Red Dot sight but couldn't get enough elevation adjustment (returning the sight). An airgun in this price range should have better sights. Another issue is really a design flaw. The BB reservoir sticks up high enough that you need to be careful when ordering an optical sight to insure there is enough clearance for the sight to work.

Pros
Accurate Powerful for a CO2 BB gun Controls easy to use

Cons
LOUD Crude sights (if you want to use the EBOS for pest control you will need an optical sight) Loose cover on BB reservoir comes open too easily BB reservoir has a high profile and can block some optical sights

a lot of fun. A lot easier to load than the steel storm. The 88g co2 last a decent amount of time but are expensive. everyone likes auto fire mode.

By CarolynUSAOctober 19, 2015

The idea of the automatic machine gun is exciting. IT would be better in a pellet version and also the bb's jam quite a bit. CO2 is expensive.

the CO2 cartridge leaks out once it is screwed into the Gun. Seem that there is an internal leak. Any thoughts?

asked John from USA

If you leave the co2 connected for a long period of time it will swell the seals and O rings causing a leak. Get yourself an inline co2 / hpa on/off adapter and you will be able to shut off the flow of co2 when not in use. BTW you will also need a co2 to paintball adapter.

Robert

try putting lube on the seal before install this will stio the leaking , if it is leaking in side send it back it means it has bad seals thanks .

chad

Mine did the same thing, at first it wasnt very loud but it got worse, not long after it started doing it the electronics shorted out, I'm thinking the leaking co2 got cold and condensed on the electrical board and the whole gun went dead. Now it's in a garbage dump somewhere. I really liked it until it died, I'm thinking of getting another one.

William D from USA

Take a look at the pin and "O" Ring where the CO2 cartridge is installed. If there is a GREEN O-ring set in the seat that seals the CO2 cartridge it may be compressed to the point where it's too thin to seal the cartridge. I believe it's a plastic O-Ring that can lose it's elasticity and doesn't rebound to it's original shape. In other words, the O-ring has lost some "FAT" and flattened out. My personal experience is with a Umarex Morph, the 3 piece gun that is a pistol and "morphs" into a carbine with a barrel extention . It a good gun until I made the mistake of leaving a CO2 cartridge installed in the gun for a few months. As soon as I inserted a fresh cartridge the gas would leak out of the cartridge. After wasting 5 cartridges I called the vendor and found out that Umarex doesn't repair this gun. They have NO parts to even send to a customer so they can attempt to repair it. Fortunately, even after a year of using the gun the vendor volunteered to send me a brand new unit. They didn't even want the old unit back to look at. THAT'S GREAT Cust. Service. BTW, I spoke to Umarex U.S.A . They are located in one of the Southeastern states, maybe Alabama. Aftr hearing my story they boldly told me that they can't help me at all. So I asked if they considered the gun to be a throwaway They had NO response, TERRIBLE Cust. Service.

Stephen Kenyon

Add some oil to the cartridge before putting it in this helps keep the seal

Rabbit

Seems like a manufacturer's defect. I had my EBOS for about a year now without any leanks.

Zane from South Africa

I've had no problem with CO2 cartridges sealing properly in my Ebos. I use Pellgun oil on the tip of each new cartridge and I check periodically to make sure the cartridge hasn't worked itself loose because of the vibration. If you're not using Pellgun oil, try it and your problem will likely be solved. Good luck!

HB from USA

I have had this gun for almost 6 months and no problems whatsoever ...awesome rifle! you must have got a faulty gun

Brian from USA

Is your Umarex EBOS Brand New?!....If it is, I would contact the MFGr, but It seems that mine did the Same exact thing, and I Have Owned (2) Of these...Mine are just sitting there in a box right now, and Would like to have mine repaired Too..Probably some kind of inner check-valve...

Richard from USA

I use the red oil to the tank and body connection

Paul

Will laser sight fit if so which ones

asked Quentin

I purchased - NC Star Red Dot 4, D4RGB, Reticles Red & Green Illumination. I am very pleased with the sight.

Carl

Any Of the Laser Sights on the Market, with a Picatinny/Weaver rail Mount Should Work, as This BB Pistol has A Weaver Mount right on Top, and One on the Lower front part, which the Forward Grip is Already Attached To...

You may order from our website, which will calculate shipping as well as inform you of any possible restriction issues. Please let me know if you have any questions.

Scott from USA

Is the barrel rifled or smooth bore?

asked Eric from USA

Smooth it's bb so would destroy a rifled barrel but still extremely accurate

dennis from USA

Smooth

Frank from USA

can you put the blackbird mod chip in this gun

asked jake

No, the Blackbird chip is desidned specifically for the Drozd.

JimC Innovations from USA

Can we adjust the velocity of this gun under 500 because it's not legal in Canada

asked Anthony

Sure...try shooting paper spit wads out of this and I'm sure that'll take the speed down a tad!!!

Steve Lewis

I have not found a way to lower the fps but I believe it to be lower than 500 anyways.

derrick from USA

Does this BB Rifle come with Full auto? and can you ship to New Zealand , How much for rifle and shipping? do you have in stock? thanks

asked Tony Hartley

Tony, Please contact our International Shipping Department at [email protected] They can answer any questions you might have. Sincerely, The Airgun Depot Customer Care Team

Scott from USA

good morning, My name is Dan Bell. I own AMERICAN SHOOTING SYSTEMS.com.... we specifically target air rifles for our target systems. Would you think this is a good gun for our targets? I think fantastic, but is 540 fps enough uummph to get good can response?

asked americanshootingsystems.com

540 fps is good for shooting cans but only until the co2 container gets cold or starts to get low. This gun has a high rate of fire and tends to freeze quick. So to answer your question yes it is enough uummph for the first 125-150 rounds.

derrick from USA

how is this rifle

asked alvin lewis

This rifle works fine. There are no leaks or other problems. Very good rifle for this price. I will recommend it for everyone who is going to get bb rifle.

Reino from Finland

Hello, I want buy this gun I'm new in guns . I want to know where I can buy co2 ammo and bullets of this gun ammo , but I need the best and stronger ammo , I will be happy to link,thanks

asked Michael

Michael, We sell the CO2 and BB's here at Airgundepot.com. There is really no difference between the Co2 cartridges and brands. however when it comes to the BB's make sure you get the zinc or gold coated. They will be stronger then the copper. Hopefully this helps answer your question. Sincerely, Airgun Depot Customer Care Team

Scott from USA

Is it loud

asked Joseph

Not at all. For a gun with this power it is surprisingly quiet. It can be made even quieter by installing a compensator which is available at the Airgun Depot. By adding tape to cover the holes on the compensator, it becomes as quiet as gun with a silencer.

Charles from USA

Will a scope or red dot sight attach to this? If so which one?

asked wayne

Yes it has the standard Picatinny rail , so most dot scopes will work, and you need one because the factor sights are total garbage. They do have to have enough elevation to get over the front BB storage area. I'm using a Leapers Red/Green dot. It requires no additional height.

William Hughes

can you shoot this gun with out the co2 tank

asked joe

Joe, Unfortunately, this particular gun only works with Co2. It uses a 88g CO2 tank. Hopefully that answers your question. Sincerely, Airgun Depot Customer Care Team

Scott from USA

Hi, how long does the batteries and gas last for? Also how many shots do you get out of the co2? Does it come with co2 and BB bullets?

asked Jacob

I have run about 10,000 rounds through the gun and the 6 Duracell AA batteries show no sign of weakening. I get about 350 shots per 88 gram CO2 cartridge on single shot. Probably a lot less on the burst settings. It does not come with CO2 or BB's. Hope this helps!

christopher from USA

Stupid question, I know probably not, but to double check could you use this for air-soft matches? and can you use plastic BB's in it?

asked Jordan from USA

Jordan, No, this bb gun fires steel bbs only and could seriously injure another person. This particular bb gun is not an airsoft rifle and, therefore, cannot fire plastic bbs. Please let us know if you have any further questions. Sincerely, The Airgun Depot Customer Care Team

Scott from USA

Is the exterior of this rifle metal?

asked jane

good afternoon friend I wonder if you send to Brazil? and what value? thank you

asked Lucas

Try checking out at the sight and if there is a restriction you will get a warning before you purchase the product. There are a lot of different regulations for all different countries and they are always changing, so we have set up an automatic warring if there is a product, based on your location, that is forbidden. Shipping price always changes, but you should be able to see the final price before you complete your purchase.

Scott from USA

Hello where do I purchase the barrel suppressor that's in the video, or does the gun come with it/ thanks in advance

asked mitchell

Look on Umarex's site or pyramydair's accessories page, they have them there

Jake from USA

do i need a liscense for this gun and can it drop crows and coons from a little bit of a distance

asked ihatecrows

Orders placed from the following areas will be refused due to the laws, restrictions and conditions of sale in your state or city: New York City and its boroughs, (ZIP Codes 100xx-104xx, 111xx, 112xx-114xx & 116xx), New Jersey (FFL required), Chicago, Michigan and Philadelphia PA and Washington, D.C. We cannot ship Co2 to Alaska, Hawaii Puerto Rico or any foreign country. Some restrictions may apply on sling shots and blank guns in some cities. It is your responsibility to know the laws in your area.

Scott from USA

I noticed they said the front sight was adjustable, but it is not. What is a weaver mount and an optic compatible tactical rail?

asked CRYSTAL

A weaver mount is used primarily on military and tactical weaponry in order to quickly and securely attach scopes, lasers, ANPQ and so forth. An optic compatible tactical rail is exactly what it sounds like, a Mounted railing on the top of the upper receiver (flat top of the gun) that makes it possible for scopes, Red dots, ACOG sights ect to be mounted.

Jake from USA

Where do you find the chamber lube for Co2? Also is there a laser sight with red dot that can be added?

asked CRYSTAL

do you ship to uk ?

Scott from USA

Seeing as how the velocity sits at 540, do you need a PAL gun licence to own this gun?

asked sean

It depends on your local laws. In Michigan, its a toy untill 700fps

Rick H.

Yes you do. Also it very closely resembles a real fully automatic firearm, so once you obtain a PAL, keep it in a case until your ready to shoot it safely and within regulations.

Jake from USA

Scott from USA

Can it kill a duck from 66 feet?

asked big john

Im sure your kidding bud. Because it would be illegal to shoot a duck with a rifle of any kind. And any offense involving a migratory game bird ie ducks,geese is a federal offense

William

No. Assuming your in season, I would honestly suggest skipping airguns entirely and using an actual Shotgun. Only high powered PCP's and break barrels posess the necessary power to kill a duck, and trying to hit a moving target in the air with a 17 -22 cal pellet (taking into account windbags and range constantly is changing for a midair target) is almost impossible. I have nothing but respect for airguns and they are very useful for many hunting scenarios, but at this point in time you are best to go with a hunting shotgun.

Jake from USA

Does it jam or have any problems like that?

asked solomon

As with any Automatic firearm, there is definitely the potential for a jam, but seeing as it uses roundball ammo, it's not likely.

Jake from USA

hello do you ship in france and for how mutch. thank you.

asked vincent

Vincent, Yes, we do ship to France if the right permits are obtained. The cost of shipping depends on what is being shipped. You can calculate it on our website. Sincerely, The Airgun Depot Customer Care Team

Steve from USA

Can compressed air be used with the EBOS instead of co2 if using the adapter? I am thinking about purchasing one and it would be great if I could just run a remote line with my 65 ci tank.

asked Daniel from USA

The answer to your question is YES, not some opinion of whats best in others eyes. If you find the working pressure and adjust the output of your hpa tank accordingly. HPA can work on ANY co2 gun provided you make or obtain all proper connections and adjust pressure to the running pressure of the marker/gun. It may not be best or most economical but it can work.

jeremy

It's best to simply use the co2 cartridges. Using a tank is overkill for a BB gun.

Jake from USA

Where would you buy the adapter that people are referring to? If its possible, I would like to upgrade to a 12 ounce paint ball co2 canister as well. If you have any info regarding to this mod please put it in your answer.

asked Tyler

can a 90 gram cartridge be used in this rifle

asked jim

this cartridge uses 88 gram CO2 canisters.

Steve from USA

can you put sights on this

asked demetrios

You can put different types of scopes and lasres on this gun but not iron sights.

Scott from USA

Hi, wonder if this gun is able to mount a scope on to it ?

asked kenneth

this gun can have optics mounted to it. It would be more for looks than function though. The range on this gun would not require a scope.

Scott from USA

is there a seal between co2 tank and gun that can be replaced ? screwed tank to gun and it leaks past seal

asked ralph noble

often the seal needs to be lubed, Use pelgun oil on the end of your Co2 tank should solve the problem.

Steve from USA

Would this Umarex 540fps kill small game like Rats

asked Allan

This gun will kill small mammals.

Steve from USA

Can a scope be mounted on the EBOS? If so, any reccomendations?

asked Russ

Yes, you would need something to clear the hopper on the front of the gun. High profile rings should do the trick.

Steve from USA

Can it be exported to India.

asked Ashish

Thank you for you interest. For questions about international ordering/shipping please email us at [email protected] This so we can better help you.

Steve from USA

I purchased a Umarex EBOS BB rifle, and would like to know maximum operating pressure. I'm looking into purchasing an adapter and 12oz Co2 paintball tank, but not sure of operating pressure. Any info would be appreciated.

asked Ray

Not sure of the operating pressure however I would highly recomend the adapter and Co2 tank. The normal tanks we went through in about 10min. Gun is a great toy and It's alot of fun but the disposable tanks go to fast. Upgrade to the paintball tank if you plan on purchasing it!

michelle from USA

i had a similar idea that way i dont need to put the stock handle on but opted out on getting the 90 gram co2 tank..there cheap and it fits nicely in the stock...wallmart has em for about 12 bucks for 2...hope that helps you

oleg from USA

I do not use Co2 I only use green gas or propane which have the advantage of not freezing up so much when you shoot at a high rpm .

Roberto from USA

Do you need to purchase the adaptor? What is it for?

asked Sheri Doback

The bulk fill adapter is so you can use bigger refillable Co2 canisters. This is not a necessary attachment as you can use 88 gram tanks.

Steve from USA

Can a 90gram CO2 cylinder be used in the Umarex EBOS or does it have to be 88? A 90 will fit, but the gun make electronic noise only - without firing a shot.

asked jake

Don't know about the 90g.....just use the 88g.

Conor

The external sizes of 88g and 90g CO2 cartridges are almost identical. The thread size is the same. The length of the dog point is the same. If everything is in working condition, there is no reason a 90g will not work in your Umarex EBOS. Trouble Shooting: I would check that your batteries are fresh. Then, if it still isn't firing, I would check if the cartridge was punctured. After that, I would check if your puncture pin is damaged or blocked. Checking your warranty would be the next step. Personally, I only use 90g CO2 cartridges now. I really like using JT 90 Gram Prefilled CO2 Tank, because they are very economical compared to 88g Crossman AirSource by 40% and 88g Walther by more than 50%. As far as getting more bang out of a 90g vs. 88g I would venture that you get a whole clip load more, but I haven't tested this. Feels exactly the same in every aspect except my wallet.
