The Umbrella Corporation Weapons Research Group has been making expertly crafted weapons and weapons accessories since 2007. The design philosophy behind Umbrella Corporation is to offer practical, functional, and well thought out weapons systems that far exceed the expectations of the consumer to provide a definitive advantage.

The Helios Umbrella Corporation WRG M4 faithfully recreates the details of the real rifle. This AEG features high-detail Umbrella Corporation trademarks stamped deep on both side of the receiver, giving it an authentic appearance. The rifle features a light weight, ultra-slim machined aluminum MLOK free-float handguard, prefect for mounting all kinds of MLOK accessories. On top of the rifle you'll find a full-length 20mm Picatinny rail for optics as well as a set of folding front and rear iron sights. The functional bolt stop holds the mock bolt open to give easy access to the hopup adjustment dial.
Internally the Helios Umbrella Corporation M4 features a Tokyo Marui compatible Ver2 metal gearbox featuring heat treated reinforced high speed steel gears (13:1), 8mm steel bearings, full steel toothed piston, and high compression piston head & cylinder. The gearbox was meant to be incredibly high performance right out of the box, while at the same time offering an excellent platform for further tuning and specialty builds.
The Helios Umbrella Corporation M4 borrows a unique feature from CYMA that is the Quick Buffer System (QBS) which allows for rapid spring changes that can be done by hand. This efficient new system only requires the removal of your buffer tube castle nut to gain access to the captured guide rod and spring. No longer is it necessary to break open your receiver or even remove your stock from the buffer tube to change a spring.

"So far so good about 1k rounds and still working perfectly will update at a problem.

"First and foremost, I have the carbine length barrel.
Man I gotta say, moving from a 200 dollar cyma m4 that I slightly modified, to this is a huge jump. My last gun had a prommy 6.03 and a flat hop bucking with a prowin hopup. This gun stock shoots just as good if not better in terms of accuracy, im so impressed, its literally a laser with .28's. Second the gearbox. all I had done to my last gun gearbox wise was a shim, and it shot good, but man this thing is miles better, i mean its already shooting faster than my old gun and the battery isn't even fully charged. And the build quality, both guns had excellent build quality, however this gun has a lovely matte finish, only thing that isnt so solid was the crane stock and it was just the plastic part, the buffer tube was solid as a rock. My last gun was pretty similar in terms of build quality, but this gun id say is slightly better. Only thing im worried about is the microswitch trigger going out. it hasnt yet but im hoping they fixed it. i noticed that it came with a rotary metal hop up which shoots incredibly. Gun chrono was at an average of the mid 370's for me, perfectly within the range I want, though it would be nice if it was in the 390's. Overall, this gun is absolutely fantastic, only thing I'd watch for is the microswitch, I'm not sure if they fixed it or not.

Excellent build quality except for crane stock
Gearbox performs incredibly, super snappy and insane rof
Accuracy is actually amazing, i was surprised. the range was also very good. at least 180 feet it seemed like
looks really nice, the orange tip was also easily removable, but the pin was not
its actually pretty light, i thought it would be a bit heavier, but nope! at least for the carbine length and under, younger players should be fine

not really much, but i the microswitch trigger wasn't fixed then that would be a problem
crane stock feels cheap and it wobbles.
Iron sights arent really my style, the peep hole was so small i cant see anything.

All in all, amazing. Amazing value for what you get.
