DISCONTINUED ITEM

We're sorry to say that this item is no longer available for purchase at Airsoft Megastore.


NOTE: Buy your mystery box now! Only few left before we fully run out!

Our take:  The CYMA CM507 AEG is a perfect balance between affordability and performance, especially if you’re considering on picking up an airsoft rifle that won’t wear out your wallet.  This CYMA M4A1 RIS Airsoft Rifle, constructed of  lightweight ABS polymer receiver that significantly minimizes weight, features a FULL METAL Version 2 gearbox.  This makes it shoots hot up to 410 FPS (w/ 0.20g BBs), making it one of the most powerful polymer body AEGs that you can get for under $120.  For improved durability, the standard M4 barrel is made of full metal.  The railed handguard provides plenty of space for mounting your favorite accessories (tactical foregrips, laser units, flashlights).  And a retractable crane stock has an easy-to-remove buttpad that makes it easy to install nunchuck batteries.  The CYMA CM507 M4A1 RIS comes with everything you need to field it right out of the box, including an 8.4V nunchuck battery and standard wall charger.

Features:

- Full metal Version 2 gearbox
- Full metal outer barrel
- Lightweight polymer construction
- Quad railed handgaurd
- Retractable crane stock
- Removable carry handle
- Flat top receiver optics rail
- Adjustable front and rear sights
- Front and rear sling mounts
- Battery and charger included

Specifications:
Operation:  Electric Automatic
Build:  Polymer Receiver, Rail System, Buffer Tube, Stock, Motor Grip / Metal Outer Barrel
Firing Modes:  Semi-automatic, Full-automatic, w/ Functional Safety
Muzzle Velocity:  400 – 410 FPS (w/ 0.20g BBs)
Gearbox:  Full Metal Version 2
Magazine:  300rd High Capacity (w/ gear wind-up)
Battery:  8.4V Nunchuck (included)
Inner Barrel Length:  363 mm
Hop-Up:  Adjustable
Weight:  4.5 lbs
Overall Length:  31.5" in. / 34.5" in.

Ammo type:  Seamless 0.20g or heavier (0.23g, 0.25g, 0.26g, 0.28g, etc) BBs.  For maximum performance and accuracy, Airsoft Megastore recommends GoldenBall ProSlick BBs which carry perfect spherical consistency and density, available at Airsoft Megastore for the lowest price on the market, guaranteed.

Package includes:  Airsoft rifle, high capacity magazine, 8.4V nunchuck battery, standard wall charger, cleaning rod

Color:  BLACK

Battery Charger Recommendation: 
Although this fully automatic airsoft rifle comes with a standard wall charger to charge the battery, Airsoft Megastore recommends the use of a smart charger to avoid overcharging the battery(overcharged batteries may cause decreased airsoft gun performance and may shorten battery life significantly).  Smart chargers not only shorten charge time significantly (up to 800% faster charging), but more importantly, also automatically shut off once the battery is fully charged to avoid overcharged batteries.

Great little weapon

"Lots of plastic but man this thing feels SOLID and it performs great.mags fit snugly and don't wobble,it even takes mags from a sporting goods store perfectly!!! And it gets a good range and accuracy Pros. accurate.(like all CYMA's shoot HARD(smashes right through a box at around 10ft.) Full metal outer barrel. plastic seems durable. takes almost any mag! so cheap easily upgradable. cons. not a hot rate of fire(it's ok I was just aiming for higher.) like I said it shoots hard may not help you at a CQB field but I guess you can always brake it in (just run like 2,000 rounds through it on full auto see what happens) overall great buy for 110$ totally recommend it."

Well rounded gun

"I just got the gun and went out to the field it chronographed 400-415 FPS (with .20 g) The gun worked perfectly shot straight fast and far. It even competed with pneumatic airsoft guns. Small mag wobble. Great gun over all."

impressed

"I am very impressed. This gun came out of the box with only the slightest wiggle on my stock. I didnt see a single scratch on the gun. The gearbox in this gun is put together amazingly. The power in this gun is extremely impressive for the price. For being a polymer body it is very sturdy. This gun also kicks pretty hard for not being a blowback and all together feels really nice in your hands. I will be upgrading this gun as time goes on and repost on how it went so you are aware of its upgradability. I highly recommend this well put together gun. Get yours now!"

Great Gun

"I bought this gun to play airsoft a month or so ago it is an amazing gun with great fps. My only complaint is the latch that holds the top and bottom receivers together broke it honestly needs to be made out of metal because it is an important an fragile piece besides that it is an amazing starter gun"

Cheap

"I would like to say you get what you pay for, but that would be wrong. You don't receive what you should get, the only useful pieces of this product are the battery and the magazine. PROS: -Comes with battery CONS: -Cheap plastic -Very little is metal(and i mean little) -Terrible accuracy"

I love the pro gunbuilder by golden eagle!
The gunbuilder was very useful and made it easy for me to buy my first mid/high spec gun for just about $300. It gave me comfort in that i can get more parts to switch out at a later time if i wish to change anything about my rifle and that there will be compatible parts for any modifications i choose to do on it. The gun came in full working order and the hopup was even adjusted to be perfect right out of the box. I could easily hit targets over 150ft away constantly. Johnmstopka, USA
