The Umarex EBOS is one of the most exciting CO2 guns made. We've taken the basic gun and kicked it up a couple notches by making an adapter that attaches to a bulk-fill CO2 tank. The adapter is listed in the ACCESSORIES link for this gun. It's a simple process. As it comes from the factory, the EBOS CO2 submachine gun can use only 88-gram CO2 tanks. They will deliver a lot of shots. But, if you want to really economize, get our CO2 bulk-fill adapter (AV-00034) and pick up a 12-oz. CO2 bulk-fill tank (KM-JAA12T) and get ready to rock! You can use a 20-oz. CO2 bulk-fill tank, but it'll be pretty heavy to hold for extended periods and may not allow you to fully enjoy the experience.

Things I liked: The ability to shoot for a longer period before reloading is a plus. Having a choice of rate of fire is a bonus.

Things I would have changed: The hopper door needs a positive latch. This eats batteries if don't remember to turn it of. A timed disconnect or a trigger disconnect from the power source of some sort would be nice. a bulk air feature would be good, or accessories made available at the time of interest or at least some information for the quick adaption. The sights need improvement. You can do better walking the round on target than actually using the stock sights and to improve them you will need to purchase an after market one.

What others should know: This is a fun gun to shoot. Be prepared for some cost associated with using it.

Things I liked: 1. Highest velocity of all submachine bb guns. Tested with chronograph during 75F or warmer, I got reading 540fps. During cooler days 500-510fps. 2. This product is adapter friendly, I am using 12oz bottles / hundreds and hundreds of shoots! 3. Price and accuracy very reasonable.

Things I would have changed: Could be more quiet. Is sounds just like powerful construction stapler.

What others should know: Buy adapter and at least two 12oz bottles or larger ones. You will never regret that. I purchased also a compensator, but it was mistake. It silenced the gun only after using electrical tape but totally messed up the accuracy.

Things I liked: Great features and reasonably priced.

Things I would have changed: Seals could be better as after a year or so they start leaking the CO2 and this renders the gun useless.

What others should know: This is my second purchase of the EBOS BB gun and my 3rd purchase of an air rifle from this company. The problem with the first two was that in a little over a year they started leaking the CO2. I am not sure where to get them fixed or if the cost to repair plus shipping would be worth it as opposed to just buying a new one.

  • Mike from USA asked:

    Can "Sergey's Board" for the Blackbird be used with this? Seems like it should given similarities (6xAA, internal space, and electric solenoid, and Chinese copying of electronic fire control)

    • Joe from USA asked:

      How long will this gun last before it breaks down?

      • Omar from USA asked:

        Can you kill mice with this gun?

          No.
