The Steel Force features 6 round bursts of automatic firing fun! Also has a semi automatic shooting mode that will appeal to your more conservative side but our guess is you won't use that much. Full auto is just too much fun.

Uses two 12-gram CO2 cartridges and has lots of tactical rails. Load up the 300rd BB reservoir, which feeds the 30rd BB magazine, for constant shooting fun. The stock adjusts to a wide range of shooters, making the Umarex Steel Force a best buy.

Loads of fun but has design flaws.
December 8, 2014
I'm on my third Steel Force within a year from constant breaking from design flaws. I read all over online that a lot of people are having the same issues non stop where it just stops firing from a few weeks to months. Umarex will not talk or discuss the issue with the reasons why. DO NOT DRY FIRE THE GUN. I believe this is what sets up the gear wheel for it to malfunction and break. When sending back under the 3 month warranty they do give you, it takes about 2 weeks to get a brand new gun back. Other then the design flaws the gun is so much fun and I noticed that I shoot this more then even my AR or Sr22. Just the noise it makes from the 6 shot burst is enough for what I paid for the make it worthwhile. To much plastic but has good weight with the metal externals. As of now with all the tactical attachments I have on it weighs 7 pounds. Added a Magpul CTR MILSPEC stock, Truglow multi recitcal/dual color open red dot, FAB Defense Line TAL4 forward grip, J5 300 lumen tactical light, Laserlyte laser, and Gemtech Halo mock suppressor. I see myself everyday shooting this non stop in the spring summer and fall. Just to much fun!
Good weight, solid construction, additional rails, 6 shot burst with selector switch to single, can be modified to full auto, good co2 usage, loads of fun, anything u can just add to a picitany rail.
Could use more another rail if they moved the loading spring, wished for a steel buffer tube, no real room for 3 point sling, to much plastic, sites cannot be removed and they are cheap plastic.

Lock And Load A Steel Force
October 3, 2014
I ordered a steel storm weeks ago and had to have a Steel Force model. I mounted one of the Green Dot Laser sights on the bottom rail and sighted the rifle in in only minutes, less than 30 rounds. There are no wild rounds even at full auto, every round on target and tightly grouped. The green dot is highly visible even in full daylight and you can get on target instantly. Other than plinkin' I don't know what I'll do with the weapons but at full auto I at least know what I can do if needed.

Get it while you can
August 9, 2014
I bought the Steel Force from AD a month ago and I'm very pleased with it so far. I live in Sweden so I had to import it because no dealers here carry this gun (for some reason). Obviously the burst mode is a major selling point and it's just as fun as it sounds! I have only fired a couple of hundred rounds because I have been busy modding it. Take a look at the attached pictures to see what I have done with it so far (full-size metal magazine, cut-out ejection port with a new metal ejection port, weights added internally etc.). I recommend this airgun to anyone in the mood for some great plinking and can-shredding sessions. And don't worry too much about the plastic - the Steel Force is still a riot to shoot, and the price is not bad at all. /Fredrik
Burst mode, the AR look, rails, trigger pull
A bit too much plastic, no adjustable sights, the flash hider was not fitted tightly enough (I corrected that myself).

Fun while they worked!
February 19, 2014
At first this gun really met my expectations. It%u2019s a blast to shoot and the single or 6 round bursts are great. If you feather the trigger in 6 round bursts it almost like full auto. My thumb gets in the way of the magazine follower as others have stated but I generally hold the front portion of the magazine. You can get 210 - 240 shots through it however, when the co2 pressure starts to get low the gun will fire multiple shots in single shot mode or only shoot 1 six round bust and stop firing. If you pull the charging handle it will fire again but then fail. This must just be the way the gun acts when the co2 pressure gets low. However, after a couple thousand rounds through the gun it would misfire even with fresh co2 and the charging handle would need to be pulled to get the gun to fire again. Sometimes it would fire 10 times and stop while other times it would fire 1 shot and stop firing. It eventually stopped firing altogether. I called Umarex and they had me send it to them as it was still under the 90 day warranty and they replaced the gun. I've got around 2000 rounds through the second Steel Force and the gun started misfiring again with fresh co2 carts just like the first one. I called Umarex and they had no explanation. They said there are no known issues with the gun. I followed the instructions meticulously so I%u2019m not sure what is going on. Luckily, I had one day left on the 90 day warranty so I sent the second Steel Force back to Umarex to be looked at and hopefully replaced. Maybe I just got two lemons. I%u2019m very disappointed, especially with such a fun gun. I would have given this gun 5 stars but since two of them stopped working after only a short firing time I can only give it 1 star. Hopefully Umarex will replace the second gun with one that will last tens of thousands of rounds.
Looks, good shot count per co2, accuracy, single and 6 round bursts with plenty of rail space for accessories.
The sights are not adjustable and cannot be removed. Stops firing after a couple thousands rounds.

great gun over all
December 30, 2013
i love shooting it because it has amazing accuracy and it fun to shot because it has a high power out put, and the best thing is you can get about 600 shots out before the CO2 runs low.
little flip up sights

Great Addition to any collection
December 19, 2013
Overall, this is a great addition to your collection. It is an affordable gun that not only provides a cool look for an assault rifle, but it is also provides great function at this price point. You can shoot one shot at a time or in six round bursts for full auto. It has a very realistic feel and weight to it - especially after you're done adding your attachments. I have a red dot scope, flashlight, grip and laser pointer on mine. I would recommend it to a friend.
You will have fun with attachments and can really make it look great!
If I have to list a con it would be that I would have preferred more metal parts (like the sights), but for the price, I won't complain.

Fun and accurate.
November 25, 2013
This is my first semi-auto/ full auto BB gun; I have about six. Pumps, pistols, Co2's, and lever action. I was hesitant to try it because I wasn't a big fan of Co2's. I'm glad I did. I poured respectable amount of bb's in the reservoir, tightened the screws on the magazine, releasing the gas and rock & rolled. It's not that loud which is a plus. I'd say more quiet than a nail gun. I like the unique magazine which holds the Co2's. It's much like an actual magazine for an m-4. I shot with the fixed sights from about 20 feet. Single shot and six rd.burst. It shot about about 2 inches beneath the bull's eye. Its not too bad; the Co'2s lasted better than I expected. With the picatinny rail you can upgrade with a scope or red dot hardware. It's a fun bang for the buck.
A fun plinker and target shooter.
It would be a nice feature if you could purchase spare magazines for it. Not that you burn through it that quick but, it would be nice to have the option.

Steel force
October 16, 2013
Rushed home knowing my delivery was waiting . Opened the box and started shooting right away . Right off loved it , how cool is six shot burst from an air gun for under 120 ? I did notice when the co2 was low my single shot mode went to 6 shot . Replace co2 and back to Normal . Sights not so hot , but just slapped on a red dot .
O2 powered . Single or 6 shot burst . Adjustable stock . Affordable . Lots of rail space for mounting what ever you would like.
Low co2 creates fire rate control issues , still doesn't bother meas I love the gun . Sights not so cool . Bb mag driver hits my thumb when firing.

Perfect, shoots like a nail gun. It works great on moving squirrels since so many BB's are flying at them you are sure to make the squirrels go elsewhere.
All well thought out.
None at this time.

Very cool looking gun
August 7, 2013
Grand kids loved the ease of shooting in regards to the trigger pull and the telescoping stock. Sights aren't the best but I installed a halo sight from one of my AR15s and it is a tack driver on the zombie targets. Full auto 6rd burst is a nice feature.
Looks very close to my SBR in size also. 6rd burst Nice shooting gun for the price.
Stock sights aren't the best but then for the price who cares, you can always put something else on it.

Couldn't wait to get my hands on one of these
June 20, 2013
This gun met my high hopes. A blast to shoot. It will cut a soda can in two with a 30-rd magazine (five 6-rd bursts). Since my thumb gets in the way of the magazine follower, I will probably add a pistol grip to the forehand (or else have to find a new way to grip it). I feel like I have to get my head really low with the flip up sights, so I will probably add an optical sight to it which is a little higher. That would make it more comfortable to shoot so I don't get a kink in my neck. I wish they would have a 30 or 40 rd (or more) drop out magazine (that I could get extras of) to make reloading easier and faster. The first day I shot it I put quite a few 30-shot mags through it (I lost count). Then after I would fire a 6-rd burst, I was unable to fire again. So I pulled the charging handle back and fired another burst. Same thing happened. I had to pull the charging handle back each time I fired a burst. I thought maybe the CO2 was running low, so switched to single shot mode. However, it continued firing 6-shot bursts. I switched to safe, then back to single shot and it still happened. I emailed Umarex about it and they promptly replied. Told me to send it back and they would take a look at it. I decided to put a pair of fresh CO2 carts in and test it out again. This time I kept track of how many 30-shot mags I could get out of a pair of CO2 carts. It worked flawlessly through eight 30-rd mags (240 rds). I reloaded and halfway through the 9th mag full on 6-rd burst mode, the same thing started happening as the day before. Switched to single shot and it fired it twice with one round per shot, then it started firing bursts again in single shot mode. Apparently the "malfunction" is related to CO2 pressure. I am going to hang on to it for a while to see if anyone else encounters these phenomena when CO2 runs low. If so, then I guess it is "normal". If not, then I will return it.
looks got 240 shots out of a pair of CO2 carts good accuracy and on target right out of box good fps drop out "magazine" holds a pair of CO2 carts, also stores the CO2 wrenches (one extra - nice touch) 6-shot burst on auto collapsible stock rails for accessories
flip up sights sometimes flip down filling the 30 rd magazine from the 300 rd hopper is slow and requires tilting the rifle up and down repeatedly the magazine follower is right where I normally put my left thumb, so my thumb gets in the way flip up sights are a little low for me
