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.
Pro: I have heard about that the mosfit is bad but so far its working fine. With a 11.1 its like 30prs and 9.6 Nihm 20rps. It shoots crazy fast and its accurate asf
Con: The problem is that you will need good Mid-caps to fed well. The mag that it comes with works great and holds a lot of bbs.
Over all a great gun!

"I'd like to point out that if your intention is to run this outdoors at a target FPS of 400 , and you're not a confident tech, do not buy this rifle AND YOU WILL NEED AN AR TOOL!

I was very hesitant about purchasing this rifle due to reviews consisting of;
1. Microswitch malfunction
2. Poor airseal

I'm very happy with this purchase!

1. The metal work externally is precise and well manufactured
2. The QBS system is easy and fast to use and I believe that all manufactures should use this design
3. The microswitch trigger is snappy, responsive, and replacing the trigger is simple
4. I've never taken a gun apart so quickly in my life! It took me a half hour for all the work (listed below)
5. It was worth it!

1. Be careful when removing the castle nut because the threading can be damaged easily while using an AR tool.
2. Not so much a con, but I'd refrain from pulling the trigger at all unless ready to fire because the microswtich triggers are known to snap

I've installed the following and the parts are available at Evike;
- ASG m115 Spring
- Angel Custom 6.01mm w/ RHOP (250mm inner barrel)
- Angel Custom HDR Flat-Hop Nub
- Modify Baton Soft Bucking
- Lonex Stainless Steel Cylinder for inner barrels 240mm-510mm - NOT PORTED
- VFC air seal Nozzle
- G&G M4 trigger for G&G MOSFET 2.0 (Red) - I bummed this off a boneyard version
- Lonex High Torque motor (orange base) - yes, it works

*Currently I'm using the stock hop-up, but may upgrade to a Prowin and I'll chrono soon; I'll update as needed*
