Umarex EBOS CO2 BB Machine Gun Review
Type: CO2 BB Machine gun.
Manufacturer:UmarexUSA.
Model:EBOS. (Electronic Burst Of Steel)
Materials: Plastic (polymer) and some metal construction.
Weight: 2.95 pounds.
Barrel: 9.75 inches, metal non-rifled.
Propulsion: CO2 x 1 (88 gram).
Action: Semi/Full auto 1-4-8 shot burst, electronic trigger motor driven.
Ammunition Type: 4.5mm BB's
Ammunition Capacity: 360-400round hopper with 24 shot internal spring fed magazine.
FPS: 540 (single shot).
Trigger Pull: The trigger on the Umarex EBOS is electronic so it does not have any real distinct break point or resistance to it. It is essentially a switch that actives a motor and the motor operates the CO2 valve. It works very well and even in single fire mode you can fire very quickly, almost as fast as when shooting in 500 rounds per minute mode but with a lot more effort from the user!
Accuracy: I shot this CO2 BB Machine gun at a target from 30 feet away using my EOTech Styled Red-Green Dot Tactical Scope in a semi rested standing position, and it performed excellent getting a little over a 1 inch grouping fairly centered on target. I also performed my accuracy test in full auto 8 round burst mode and although the grouping did get a bit larger, the EBOS still stayed well on target. I decided to use a partially used 88 gram CO2 cartridge to see what the EBOS could do in a very real world Feet Per Second test and I was able to get a 481 fps average 8 shot result which was very good considering I was well into the CO2 tank at that point. On a brand new CO2 cartridge, attaining the maximum claimed fps rating is very achievable.
Build Quality: The EBOS is an almost all external polymer air gun with some metal components on the inside. For the most part it feels solid and has good weight especially when you load up the 88 gram CO2 tank and slap on a Red Dot and a couple other accessories. Everything seemed to operate as you would expect and I especially liked the easy access to the CO2 and well designed rear stock which conceals the CO2 cartridge very nicely. My only concern with the EBOS is the front barrel which protrudes out from the EBOS a bit and because it is made of plastic, it may be prone to breakage in the event of a drop directly onto the barrel.
Realism: The Umarex EBOS BB machine gun doesn't closely look like any specific Tactical rifle, but does have that very assault rifle look to it. It almost looks to me like something from a Science Fiction movie!

Pros:
Inexpensive full featured BB machine gun at just over $100.
Very good accuracy in all shooting modes.
Excellent power - right around the 500 fps mark even on a well used CO2.
Uses the 88 gram CO2 - you're going to need it!
Has two rails for accessories and comes with the fore-grip.
I liked the high 8 round full auto burst option.
Nice stock design and easy CO2 access.
10 out of 10 on the fun factor.

Cons:
The all plastic exterior may put off some people looking for a heavier more metal gun.
88 Gram CO2 can be a bit pricy, not as cost effective as 12 gram CO2.
The rear sight was way to wide - it is the first thing to replace or upgrade.
The plastic barrel worries me just a bit in the event of a fall?
Comments:
The Umarex EBOS is a really - really fun BB gun! That should almost be enough right there to buy it on the spot as it's not all that expensive all thing considered! The EBOS has a lot going for it, nice high up to 540 fps velocities, very good accuracy for a BB shooter even in full auto mode, a high capacity CO2 and BB feeding system, versatile shooting selection (1-4-8 shot burst) and (300-400-500 rounds per minute), the ability to add accessories top and bottom and a price tag that is very reasonable. Unfortunately this Umarex product is not that readily available here in Canada because the scary 540 FPS rating on the box, but for you non-Canadians, you're in luck so make sure to think about us Canucks when your spraying BB's with the Umarex EBOS.
