Once a year, after the SHOT Show, airgun manufacturers will frequently send me their latest catalog as part of their press kit announcing what’s new and interesting. These catalogs prove invaluable because, as the year wears on and I am looking for something to write about, I’ll pull out a catalog or two to see what might be a fun subject for a blog.
So that was the scene a few weeks ago as I paged though the catalog from UmarexUSA. When I got to page 35, I noticed something called the E.B.O.S. It is a BB gun that boasts 540 fps and “8 shot burst!” Could be interesting, I thought, so I called the nice people at www.umarexusa.com and asked them to send me an E.B.O.S.
One arrived a few days later in a deceptively small box. When I first pulled it out, it looked like a two-handed air pistol, but I soon realized that there is a buttstock that attaches to the main receiver. E.B.O.S. is an acronym that stands for Electronic Burst Of Steel. The EBOS is 24.75 inches long and weighs 3 pounds. It shoots .177 steel BBs and is powered by an electronic action and an 88 gr. CO2 cartridge (not included).
The entire EBOS appears to be made of matte black engineering polymer. Under the pistol grip there is a slide-off hatch into which you insert 6 AA batteries (not included) that provide power for the electronic trigger and firing mechanisms. Forward of the pistol grip, the engineering polymer forms a guard around a black polymer trigger. Forward of that is an additional grip that can be moved fore and aft along a rail under the receiver.
Above the rail on the left side of the receiver are two selector switches. One allows the shooter to SAFE the action so that it won’t fire, and the other allows the shooter to select 1, 4, or 8 shots to go down range when you pull the trigger. Above the two switches on the left side is a 24-shot BB magazine and a bb follower that pushes the BBs into the breech as they are needed.
At the extreme front end of the EBOS is the plastic muzzle which has threads that could possibly be used for mounting a barrel extension or faux silencer. On top of the receiver at the front end is a large capacity reservoir that can hold 360 BBs and the back edge of which incorporate the front sight.
Below the reservoir on the right side of the EBOS is another switch that can be used for selecting 300, 400, or 500 shots per minute. Moving back along the top of the receiver, you’ll find a Weaver/Picatinny type rail that can be used for mounting a red dot or scope. At the aft end of the rail is the notch-type rear sight which can be adjusted for windage.
To ready the EBOS for shooting, open the hatch under the pistol grip and insert 6 AA batteries in correct orientation. Next, screw an 88 gr CO2 cartridge into the back of the receiver. Slide the buttstock over the CO2 cartridge until it latches. Finally, having made sure the EBOS is on SAFE, slide the hatch back on the BB reservoir and pour in a generous supply. Pull the BB follower toward the muzzle and lock it in place. Shake the EBOS until 24 BBs load into the BB magazine and gently release the BB follower. The EBOS is now good to go.
Take aim at your target, slide the safety off, and squeeze the trigger. In single shot mode, I found the EBOS would launch steel BBs at around 525 fps. If you begin to shoot quickly, the velocity drops to around 449 fps average (on a 70 degree day). If you change the selector switch, you will indeed get 4 or 8 shots bursts.
I discovered the purpose of the EBOS while collecting my pellet trap from the garage. One of the empty soup cans that I keep for penetration tests made a smart remark to me, and I decided then and there to teach it a lesson. I tossed it into the driveway, flipped the selector to single shot and cut loose. The first couple of shots blew cleanly through the sides of the can.
Then I put the selector on 4-shot burst: pow-pow-pow-pow! The can fell over and began rolling around in an effort to escape. I flipped into 8-shot mode: pow-pow-pow-pow-pow-pow-pow-pow. I walked over to inspect the shredded can. “I’m sorry,” it said. “You should know better,” I said as I consigned it to the trash.
The EBOS is simply excellent for bouncing cans around, and I imagine it would be great fun with whiffle golf balls or a bag full of dollar store dinosaurs. If you decide to indulge yourself, make sure everyone on the firing line is wearing eye protection because BBs will ricochet, and, as always, be sure that you are firing in a safe direction where no people, pets, or property will be damaged.
Til next time, aim true and shoot straight.
