Umarex Legends MP40 BB Submachine Gun

Pros
if using the suggested bbs the jamming stop but the power is weak.i dont beleive its 450fps,the bbs bounce off a basketball,no penetration.looks very good and has a realistic feel.

Cons
weak

Pros
People with magazines/co2 problem: Put your CO2 in the magazine, then when you go to puncture, hold the magazine up to your ear so you can hear the sound of the CO2 puncture it's very quiet, then very gently unscrew until you hear air leaking, once you have confirmed that the co2s are punctured by hearing the CO2 leak gently tighten until the leak stops and you'll be good to go

Won't feed in semi or full auto, even with pulling back charging handle each time-----WHY???????

Pros
Great reproduction

Cons
my response see below

Pros
Came sooner then expected

Cons
I think 3 co2's would make a big difference

Nothing

Pros
I have owned the M40 and the M1A1 Thompson BB guns for about two years now and they are fun to shoot! I do not have any problems with the Crossman C02 cartages. But I do like the silver BBs they seem to work better especially with the M1A1 Thompson. I did have a problem, I kept having to reload the darn things so I bought three extra clops for each BB gun. It was a big pain the reload 4 clips all of the time BBs everywhere especially trying to hold the spring-loaded BB nub catch to stay open while loading. So, I designed a way to load the clips very fast, it only takes a few seconds (about 3sec each clip) with no spilled BBs. I also bought a longer Allen wrench because it was difficult to judge when the C02 cartridges were punctured. I friend and war game with Plaster of Paris WWII tanks (look on YouTube “mrdstony” to see those tanks 1/35 scale), anyway we needed a close in weapon for out game and the legends guns are prefect.

Cons
Sometimes the guns seem to jam after about several hundred rounds or after the silicon oil builds up after repeated C02 a little spray of WD40 seems to clear it up, just remember to use the silicon oil after shooting on the seals of the gum.

Get extra mags, alot of Co2 if you get jams just fix it and keep going no big deal. test your item upon receipt for functionality so you may exchange it before warranty expires. then you can go ahead and display it like i have.

Pros
great replica! would purchase again. weight and feel is awesome. functions as it should and what you would expect from a bb gun. recommend.

Cons
jams do happen, but its just a bb gun so correct and move on. eats Co2 but yeah it blowback ofcourse.

Dont buy until they fix the magazine. They know it doesnt work and sell it to you anyway instead of fixing it. A sign of a bad company.

Pros
Gun part is good but magazine still has issues. Im on my second mag and uts worse that the original. They both horrible and dont feed most of the time. It doesnt matter if you stagger the bbs or not

Cons
doesnt work. Steel storm is only good umarex. Not steel force .Steel storm

I followed the included directions to a "t"! After loading the CO2 cartridges and installing the piercing screw with the hex wench I attempted to dry fire before loading to "ensure the cartridges were seated and pierced", as per the directions. It specifically read "do not load BBs until a dry fire produces a popping sound". Wouldn't work, so I tightened more. Gave up, removed screw allowing drainage of CO2 and found the O ring busted from overtightening. Called Umarex, they told me the manual was wrong, IT WON'T FIRE WITHOUT A BB! If the manual was correct this wouldn't have occurred!The O rings, piercing screw are back ordered, no ETA. I was told to try back in a couple of weeks to check again. I offered to prepay and have it shipped when it arrived."We don't do that, you'll have to call back" was the response. So, disregard the dry shot part and load the magazine, consider the crappy customer service when considering this item. My friend's worked great, he didn't read the directions

Pros
Shooting my friend's exact duplicate.

Cons
Not being able to shoot mine and having to purchase a new magazine so I could.

I have read almost everything I can find on this BB gun and watched YouTube videos. Biggest concern I see in the reviews are loading the magazines. A YouTube video cleared this up for me. Get an old rag or towel to place your magazine on; this keeps the BB's from getting away to the floor. Notice the spring has a "Locking" position (had to go back and read the owner's manual to figure this out). Lock the spring in place and feed the magazine; simple. Can use a small funnel if you choose but I load by hand; takes less than couple minutes. My biggest challenge is the correct amount of tension to tighten the CO2 tension screw on the bottom of the magazine. Beware of this very important process if you are a beginner. It is easy to leave gas in the cylinders and loose some shooting time and you DO NOT want to over tighten. No matter your experience level, read the owner's manual. Love this BB gun!!!

Pros
All metal as far as I can tell, sturdy, made to last a lifetime. Fun, Fun, Fun to shoot and is much more accurate than one would expect for a full auto. Full auto is amazing. Magazines are easy to load once you get the hang of it. Easy to clean up after an afternoon of shooting. Curb appeal of this BB gun is off the charts! Love the retractable stock (it is all metal too!).

Cons
Nothing except my wife refuses to let me purchase another!
